- 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.
- Operate the device in 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
specified maximum values.
- Disconnect the power supply and discharge the filter capacitors in the
power supply before measuring resistance or testing diodes.
- Never connect the test leads of the device to a voltage source, if the
rotary switch is set to measure current, resistance or test diodes. This
can damage the device.
- If the battery symbol appears in the display, replace the battery
immediately.
- Always switch off the appliance and remove the test leads from all
voltage sources before opening the device to exchange the battery or
the fuse.
- Never use the device with the rear cover removed or with the battery
and fuse compartment open!
