Measurement Time Setting Mode; Anomalous Cases Which May Occur During Mω Tests - Tenmars TM-507 User Manual

The message
eventual capacitors. During this phase never disconnect nor touch test leads.
9. At the end of the test the instrument
automatically discharge eventual capacitors and
parasite capacitances present among the
conductors involved in the measurement
10 At the end of the test a screen similar to this is
displayed
11 If the resistance value is higher than the full
scale, a screen similar to this is displayed.
Note! An insulation value higher than the full
scale is an
generally much higher than the minimum
requirements prescribed by standards

13 In lock mode the instrument emits an acoustic signal and the auto power off is disabled

4.6.1. Measurement time setting mode

Press LOCK more than one second, a screen similar
to this is displayed
Press the arrow keys to select the desired time value
Press GO to confirm the selected value
4.6.2. Anomalous cases which may occur during MΩ tests
If, during measurement, the input voltage
present at terminals is higher than 24V, the
instrument suspends the test.
A screen similar to this is displayed showing the
input voltage value
on the display means that the instrument is discharging
excellent insulation
Press LOCK and GO to perform the measurement in continuous
mode, the symbol LOCK is displayed. Press GO another time to
stop the continuous mode measurement
