‐
The device should not be used if the housing or the test leads are
damaged, if one or more functions are not working, if functions are
not displayed, or if you suspect that something is wrong.
‐
If the safety of the user cannot be guaranteed, the device should not
be operated and secured against use.
‐
While using this device, hold the test leads only behind the finger
guards ‐ do not touch the probes.
‐
Never ground yourself while making electrical measurements. Do not
touch any exposed metal pipes, fittings etc., which could have a
ground potential. Ensure that your body is isolated by using dry
clothes, rubber shoes, rubber mats or other approved insulation
materials.
‐
Set‐up the device in such a way that it is not difficult to operate the
network separators.
‐
Always adjust the rotary switch to the desired measuring range
before starting the measurement and engage the switch in the
proper measuring range.
‐
If the magnitude of the signal to be measured is not known, always
start with the highest measuring range on the rotary switch and then
reduce step‐by‐step.
‐
If the measuring range needs to be changed during the
measurement, remove the probes from the circuit first.
‐
Never turn the rotary switch during measurement, but always in the
disconnected condition.
‐
Never connect the device to voltage or current sources that exceed
the maximum values specified on the device.
‐
Switch off the power supply to the circuit being measured before
cutting or desoldering. Even small currents can be dangerous.
‐
Disconnect the power supply and discharge the filter capacitors in
the power supply before measuring resistance or testing diodes.
