Touching such objects is life endangering!

When a resistance measurement has been performed on a

capacitive object it is automatically discharged by the instrument
after measurement has been completed. Contact with the device
under test must be maintained to this end. The falling voltage
value can be observed at the U display.
START Do not disconnect the DUT until less than 10 V is displayed for U!

The instrument’s batteries are exposed to excessive
stress during insulation resistance measurement. Stop
