RMO30T Error Messages
8.3 Error Messages "Polarity"
The Error messages "Polarity" is displayed if:
the Voltage sense cables are connected with opposite polarity either on the side of a device, or the side
of test object, and the signal is higher than 60mV.
In some cases discharge LED can light alternately.
This message is displayed only at the beginning of a test.
Note:
If the signal is lower than 60mV the display will show result with lower accuracy.
If some of the cables are disconnected after starting the test, error message will not show up and the
received results will be erroneous.
8.4 Error Message "Change Current"
This message is displayed if during the test the voltage at the test object is too high. In this case reduce
the test current and repeat the test.
In case when test voltage is not higher than 10V per channel but test current is still improperly high for
that resistance error message „Overcurrent“ is shown on the display. Red LED will light continuously.
8.5 Error Message "Overheat"
This message is displayed when RMO30T’s operating temperature rises too high.
In this case, wait for the test set to cool down and repeat the test.
8.6 Error Message "Mains Voltage < 90V"
This message is displayed when RMO30T’s mains voltage is below 90V.
In this case, to reset the status message you must restart RMO30T.
