General

What is the main difference between MT-1/NT and MT-1/WT models?

The main difference is that the MT-1/NT testers are controlled from a handheld remote connected to the devise with a coiled cable. The MT-1/WT model has Wi-Fi capabilities so it can be controlled from any mobile device such as phones, tablets and laptops (iOs, Android and Windows). This enables much more features (cameras and GPS are put to good use!) and a very intuitive user interface. It also allows us to add more features over time. As app and firmware upgrades can be done in house at no cost, users will benefit from Probewell Connect’s evolution.

Does MT-1/NT models come with a handheld?

Yes, all MT-1/NT models are delivered in a carrying case with a handheld and coiled cable included, along with a user’s guide and calibration report.

Does MT-1/WT models come with a handheld?

No, the MT-1/WT does not come with a handheld included. It is made primarily to be controlled from a mobile device. The handheld is optional and can be purchase separately at any time.

Please note that the remote has a special programing to work with this model. The only handheld models that can be retrofitted to work with MT-1/WT models are the NTU series (this is specified at the back of the handheld). If you have an NTU remote, you can send it for programing to work with the MT-1/WT testers.

Does any of the meter tester come with accessories?

No, the accessories are optional, and you will be able to determine which ones you need depending on your meter type population. Each test requires a specific sensor depending on the type of meter. An electromechanical meter will require a Metercam to determine disk rotations while solid-state meters require a pulse pickup. Two different types of pulse pickups and two additional adapters may be needed depending on the meters to be tested. Please take a look at our Product/Accessories page for more details.

How can I retrieve and download results? Is it the same fore MT-1/NT models vs. MT-1/WT models?

On MT-1/NT models, the results are stored on the handheld remote. You can store up to 100 tests. In order to download results into a PC, you will need to use a USB device and our NTDataOne software. These accessories can be purchased separately at any time. If you are manually inserting results into another operational system, you can see the stored results on the handheld accessing the record viewer. Instructions are in the manual. Data on MT-1/WT models can be retrieved either via NTDataOne or our Windows App.

Do I need to calibrate the testers? If yes, how often?

The units are calibrated at the factory before delivery to your facilities. We suggest calibrating the testers at least once a year or as per local PUC or company regulations to ensure that your measuring instruments always perform according to expected specifications and standards. Calibration can be performed in house using a calibration kit and a NIST traceable standard. If you would like to verify if your standard is compatible, please contact us at support@probewell.com.

We also offer calibration services at our lab, please send us an email to info@probewell.com for an RMA estimate and return instructions.

Are all accessories compatible with all tester models?

Most accessories are compatible with all models. You can use older accessories with new tester models. If you own 20-25 years old accessories, some might not be compatible with the new generation models (i.e. pulse pickup PW-9071), but all new accessories can be used with old generation testers.

If you have a Metercam with a MT-1/NT unit and you would like to use it with a MT-1/WT model, you will require a different coiled cable. Please let us know if you would like more information about this to info@probewell.com

Troubleshooting

At power on the socket does not start

The socket is not powering up and no display on the handheld controller

  • Check if the fan inside the socket is running.
  • Make sure the form selector is set according to the meter base being used.
  • Verify the voltage of the meter base between 100 and 480VAC.
  • The meter base must be able to provide at least 150VA
  • Do not install tester in a testboard.

At power on the remote control does not work

If the fan inside the socket is running but the remote control’s display is blank

  • Check the coiled cables for damaged connector
  • Check the contacts of the coiled cable at both ends
  • Check the RJ12 connector on the handheld and the socket
  • Try another coiled cable

Meter under test does not work

If the meter is not powering up after selection of the form.

  • Make sure the selected Form matches with the one indicated on the meter nameplate.
  • Turn the tester off and on and try again.
  • Check meter insertion.
  • The meter could be defective. Try another meter.

No pulse found (Solid-State meters)

If the remote control displays | Waiting..... | and nothing happens.

  • “Make sure the sensor is positioned over the IR pulse emitter of the meter.
  • Some meters need to be set in Test Mode to emit a proper pulse for testing.
  • See the meter user manual”

Metercam is not synchronized with the disk

The metercam is not detecting correctly the black flag on the disk

  • Make sure the Kh of the remote control does correspond to the one indicated on the nameplate of the meter.
  • Reposition metercam and start test over again.

Metercam keeps on scanning without finding the disk

The metercam is not detecting the black flag on the disk of the meter being tested.

  • Check if the disk is turning.
  • Check the disk of the meter is in the metercam disk zone.
  • Check that the suction cups are adhering properly on the meter face. If needed, lightly wet the suction cups.

High Error or Over% result

After completion of test you have results with high value or OVER%.

  • Make sure the Kh of the remote control does correspond to the one indicated on the nameplate of the meter.
  • Without pickup, this indicates a bad synchronization at the beginning and the end of a test. Start the test again with a higher number of revolutions. The meter might be defective.
  • If the Metercam is used, make sure that the 4 suction cups stick perfectly on the meter cover during the entire test.
  • Some meter requires to be put in TEST MODE to stop the pulses from the communication module. Check meter user manual for details.
  • With a communication module, restart the test but remove the head of the Optical Pickup from the meter and select your meter form on the remote, then wait about 15 to 20 seconds before putting the head back on meter. This will let the test pulse from the AMI module pass and you will get a proper Kh evaluation.

Problem connecting to the MT-1/WT device with Probewell Connect

The Probewell Connect application is having trouble connecting to the MT-1/WT device or it is stuck in the initialization sequence.

  • If your phone or tablet has cellular data, enable the use of data for Probewell Connect in the Cellular settings of iOS or Android.

Tips & Meter Work Arounds

GE KV2 Meters

Not able to get the right KH value at start up

Description of the problem :

The GE KV2 meters at startup has false pulses from the meter self-test and will falsify the reading of the initial KH evaluation at startup of your unit.

Solution :

Before the selection of the form on your handheld remove the optical head of your optical pickup from your meter and select the form, wait 15 to 20 seconds and re-install the head onto the meter, this should rectify the problem.

Elster A3 Alpha meters

When evaluating the Kh I get a value of 0.3 instead of the KH from the Meter face plate

Description of the problem :

The Elster Alpha series have false pulses causing a wrong Kh evaluation.

Solution :

Remove the cover and with a small screw driver turn and push the test-mode switch located to the left side of the meter, this will stop the communication module from emitting and will correct your problem of wrong Kh evaluation. Remember to put bac the switch to the normal position once finished otherwise the meter registration will not record anything.

GE I-210 metes

When testing a GE I-210 meter I get a busy on the meter and my reading are wrong at the end of test

Description of the problem :

The GE I-210 equipped with AMI modules will transmit every 60 seconds and will create false pulse during the test.

Solution :

In the configuration menu, go the General edition and shorten the duration of test to 10 seconds, this will allow you to test the meter in between the transition of those pulses. Start the test as soon as the Busy signal flashes on the meter.

Itron Centron meter

I cannot find the pulse output on the meter

Description of the problem :

The Centron meters have test pulse output separate from the communication port.

Solution :

On the top side of the meter you will locate a LED pipe that is transmitting the pulse output, place the optical head there and you will be able to test the meter.

Landis & Gyr Focus AX model meters

I am not able to get a good result on LL.

Description of the problem :

The Landis & Gyr Focus AX model equipped with communication module can send false pulses during the test sequence.

Solution :

Under the cover the Landis & Gyr Focus meter have a lever that puts the meter into test mode and disable any pulse from the communication module. It is a black lever located in the center left of the from of the meter.

Electromechanical meter with TWAX or DCSI module

Not able to read the disk with the metercam

Description of the problem :

Meter equipped with TWAX modules covers the disk area and the normal metercam cannot read the disk.

Solution :

Probewell makes a variant of the metercam. The metercam Sidemount. This metercam, like the name says, is attached to the side face of the meter and will read the disk there. It is harder to aligned and if you have obstacle in the field of view it might not see the disk properly. Make sure the field of view as no wires crossing the field of view.

Electronic meters with red LED

I cannot get the pulse to be read by the optical pickup

Description of the problem :

The optical PW-9073 is an optical pickup that read IR pulses and will not see red LED.

Solution :

To read pulses from the Red LED you require the variant of the optical pickup the PW-9073V, this optical pickup is made to read visible LED.

Sensus Icon A Meter Form 3S

I damaged my Sensus Meter with your equipment

Description of the problem :

Sensus installed a MOV rated at 175 Volts between the A Phase current element and the neutral for the voltage. Our unit puts line voltage on the top 2 jaws and put a neutral on the neutral that goes either at the 6 or 9 o’clock position, which put a potential difference of 240 Volts and damages the MOV.

Solution :

We make adapter that will test 3S Sensus meters without damaging them. It eliminates the voltage difference between the A Phase and the neutral.

Sensus Icon A Meter form 4S

I am using a MT-1/NT4 and I damaged the meter with my equipment

Description of the problem :

Sensus installed a MOV rated at 175 Volts between the A Phase current element and the neutral for the voltage. Our unit puts line voltage on the top 2 jaws and put a neutral on the neutral that goes either at the 6 or 9 o’clock position, which put a potential difference of 240 Volts and damages the MOV.

Solution :

There is no fix for using the MT-1/NT4 with that meter, but if you purchase the MT-1/NT5 or MT-1/NT9 this problem is eliminated.

Class 320 Meters with plastic cover in the meter base

I have a meter base form 2S class 320 and I cannot insert my MT-1/NT3 or MT-1/NT9.

Description of the problem :

Some covers in the class 320 Meter base have covers without the holes for the B phase of our 3 phase meter testers to be inserted.

Solution :

We can make adapters that can be inserted inside the meter base and you can connect the tester onto the adapter.

Landis & Gyr with Silver Spring meter

The current is unstable when I test my meter.

Description of the problem :

The Silver Spring module induces current when transmitting.

Solution :

We make adapters that will attenuate the current inducted in our current generation transformers.

Vision Meter Form 3S

Meter is not recognized by the Probewell tester

Description of the problem :

The Vision meters with form 3S have a by-pass connecting the voltage to the current element of the Probewell testers

Solution :

Put an isolation cap on the lower C phase tab (right side) to isolate the current element.
