5 Troubleshooting
If it is suspected the device is presenting inaccurate results,
the
following tests should be performed:
5.1 Measurement Accuracy Check
If it is suspected that the device is presenting inaccurate results, the accuracy check described below
should be performed:
1. Connect the RMO-H
instrument with the test shunt 100 μΩ, as it is shown in the Figure 5.1.
2. Turn ON the RMO-H instrument.
3. Perform tests with 100 A, 150 A and 200 A test currents.
4.
Repeat the same procedure with the test shunt 1 mΩ.
5. If it is suspected that the instrument is measuring inaccurately, please send e-mail to DV Power
support team (
) with the following information:
-
Declared test shunt resistance value,
-
Declared accuracy of the test shunt
-
Result measured with the instrument (resistance, voltage drop and generated current).
5.2 Battery check
If it is suspected that the device is having battery issue or if it is not possible to turn ON the RMO-H
instrument, procedure described below should be performed:
1. Turn ON the RMO-H instrument.
2. Connect the RMO-H instrument to the charger.
3. Check if the battery is charging (charging is illustrated in the battery symbol
– upper right part of
the display)
4. If it is not possible to turn ON the RMO-H, connect it to the charger and again try to turn ON the
instrument.
5. If the instrument is able to turn ON when it is connected to the charger, wait until the battery is
fully charged.
6. Disconnect the charger and again try to turn ON the instrument.
7. If the instrument is able to turn ON, the battery is working properly.
