2. Operation
Note:
This meter is an insulation resistance tester with broad range of measurement, which can be applied for various situations
from low-voltage to high-voltage measurements.
The operation range of temperatures for this meter is 0 to 40 ºC (32 to 104 ºF).
During handling, transportation and operation, mechanical vibrations, especially vibrations during accident of falling off,
shall be prevented, so that meter damages are avoided.
In case the protecting function of the meter fails to work, please contact the supplier for service, or make distinct marking
to prevent it being used by other persons.
Only professional service technicians are authorized to calibrate and repair the meter.
The meter shall not be altered in any respect, and it can only be taken apart and repaired by the service engineers of our
company. Otherwise, it might cause fire, electrical shock and physical injuries.
When the meter is not in use, please close the cover.
Please turn off power after use.
To avoid damaging the meter, please do not insert other devices into the USB socket or the temperature sensor terminal.
Tips:
The standby status referred to in this manual is: the situation under which no measurement is being performed and no
parameter adjustment is going on. It includes the status when HOLD symbol is displayed.
In case ambient temperature changes abruptly in great number of degrees, it might result in condensation, which will
cause incorrect measurements.
Before starting the measurement, please first place the meter under the new test environment for a period of time.
