2.11. AUTOMATIC STOP
After 5 minutes of operation with no sign of the user’s presence (key press or rotation of the switch), the instrument switches to
standby.
Simply press any key to exit from standby. The instrument returns to the state it was in, with no loss information: value of the last
measurement, compensation of the leads,
∆
Rel, timed mode, alarm, etc.
Automatic switching off is disabled during:
insulation measurements in
mode and in timed mode (
).
continuity measurements, for as long as measurements are made.
This automatic switching off can be disabled (see § 2.9).
2.12. ERRORS
While the instrument is in operation, errors may be reported. The causes of any errors must be eliminated before the instrument
can be used again.

If, during an insulation measurement, the value to be measured exceeds the
measurement range (which depends on the test voltage), the instrument so
reports.
With a 100-V test voltage, the screen is as shown opposite.
V
Before the insulation measurement, the instrument is in voltage measurement
mode. If there is a voltage on the terminals in excess of 25 V and you try even
so to make a measurement, the instrument reports the situation.
Eliminate the voltage and resume the measurement.
2.12.2. OVERSHOOT OF RANGE DURING AN INSULATION MEASUREMENT
2.12.3. PRESENCE OF A VOLTAGE DURING A CONTINUITY OR RESISTANCE
If, during a continuity or resistance measurement, the instrument detects an
external voltage in excess of 15 V (AC or DC), it interrupts the measurement
and displays the screen shown opposite.
You must eliminate the voltage to be able to resume the measurement.
