- 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 device and disconnect the test leads before opening
the device to replace batteries or fuses.
- Never use the device with the rear cover removed or with the battery and
fuse compartment open!
- Do not use the device near strong magnetic fields (for e.g. welding
transformer), as this can distort the display.
- Do not use the device outdoors, in humid surroundings or in
environments that are subjected to extreme temperature fluctuations.
- Do not store the device in places which are exposed to direct sunlight.
