V1.06
10.3.
ERROR MESSAGES:
➢
"SAFETY LOOP OPEN"
: the safety loop circuit is not closed, there is no connection be-
tween points 1-9 or 2-10 of the socket C5 located on the rear panel of the device. Press
OK to clear the message
➢
"OVER RANGE":
the leakage current in the sample being tested is greater than
the measuring possibilities of the device (> 20 mA) or of the measuring range in
manual mode.
➢
"UNDER RANGE"
: the leakage current in the sample being tested is less than the
measuring possibilities of the device (< 0.5 pA) or of the measuring range in manual
mode.
➢
"CHARGING...
": the measurement voltage has not reached its final value. The voltage
generator charges the capacitor of the sample being tested. This message must appear
in a fleeting manner when switching to Measurement mode. If the message persists, this
means that the measurement voltage requested cannot be supplied to the resistance
measured.
Check with respect to the characteristics of the voltage generator.
➢
"VOLTAGE ERROR
": when a measurement time is defined, if during the test the mes-
sage
“CHARGING…”
is constantly displayed, at the end of the measurement time the
test will be declared as FAIL and the
"VOLTAGE ERROR"
message will indicate the
cause of it.
If needed see the information on the message
"CHARGING
…"
IMPORTANT
The device is equipped with a thermal protection system. In case of pro-
longed use of the High Voltage generator on a short circuit, the protection
system will be activated.
In this case the message "
OVERHEAT
" will be displayed constantly on the
LCD screen.
Turn off the device and allow it to cool down for 10 minutes before using it
again.
