WARNING
During measurements of insulation resistance, dangerous voltage up to 600 V
occurs at the ends of test leads.
It is forbidden to disconnect test leads and to change the position of the func-
tion switch before completion of measurement. Failure to obey the above in-
struction will lead to high voltage electric shock and make it impossible to
discharge the tested object.
The meter emits a continuous audio signal until test voltage reaches 90% of the
preset value (and also when 110% of the preset value is exceeded).
During measurement, the meter generates a beep every 5 seconds - it facilitates
capturing time parameters.
When the measurement cycle is upheld by pressing ENTER it is indicated by:
o a short break in the beep, when the test voltage has not reached 90% or
exceeded 110% of set value,
