LIST OF CODED ERRORS

If an anomaly is detected when the instrument is started up or in operation, the display unit indicates an
error code. The format of this error code is a 1- or 2-digit number. This number identifies the anomaly and
the action to be taken.
Possible errors :
q
The codes from 0 to 9 identify fatal errors in the hardware. The instrument must then b returned.
q
The codes from 20 to 25 identify semi-fatal errors, except for codes 21 and 25. The instrument must
be returned.
Error 20 Communication failed
Error 21 Check of options failed
Error 22 Check of contants failed
Error 23 Check of calibration values failed
Error 24 Check of instrument identification number failed
Error 25 Check of print file failed
For non-fatal errors 21 and 25, it is not necessary to return the instrument : simply use SET-UP to restore
the default parameters (Set Default Parameter).
Other possible error :
q
If it is impossible to store data, the entire content of memory must be erased using SET-UP (Clear
Memory)

5.1. COURSE OF MEASUREMENTS

§
Start up the instrument by setting the switch to the position corresponding to the measurement to be
made.
The instrument can measure insulation values from 10 kΩ to 10 TΩ, depending on the test voltage selected-
from 40V to 5100V DC.
The screen is as follows :
§
Connect the cables of the + and - terminals to the measurement points..

5. PROCEDURE

It displays :
- the battery symbol and battery charge condition,
- the test voltage selected,
- the voltage, frequency and residual current on the input
terminals,
- the date and time.
