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 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!
- 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.
- Remove the battery if the device is not used for a long time.
- If changes or modifications are made to the device, the operational safety
is no longer guaranteed and the warranty becomes void.
