If you switch from one measuring range to another whilst measurement is in
progress, voltage peaks might occur and damage the instrument.
If the voltage exceeds 60 V three-phase or 25 V AC, it is important to take
particular care as there is a risk of electric shock. The test object should
therefore first be de-energised, then the measuring range selected and the
measuring instrument connected to the test object. Only then should voltage be
applied to the test object. Whilst measurement is in progress keep your fingers
behind the shielding on the insulated handle.
Do not use this multimeter for measuring voltage if voltages of above 600 volts
are likely to develop. Do not use this multimeter for measurements in domestic
distribution systems or three-phase networks (380/400 V). Measurements on a
230 V network (e.g. domestic power circuit) are permissible.
-
Current strength
up to 10 A can be measured. The 10 A range is not fused,
and therefore measurement in this range must only be carried out on circuits
equipped with their own fuses. No voltages of above 250 V are allowed. A
measurement of 10 amps should only continue for 10 s, and must be followed
by a 15 minute cool-down period.
- Never perform
resistance measurements
on live components.
Maintenance:
If the display is blank, possible causes are:
- the multimeter is not switched on
- the battery is flat ("Battery" indicator may appear on the display)
- the rotary switch may be positioned incorrectly (between two positive
positions)
- If it not possible to measure current, the fuse for the 200 mA range may be
faulty.
Before opening the unit to change the battery or fuse, always unplug the test
cable first and move the rotary switch to "Off". Now, using a suitable Philips
screwdriver, unscrew and remove the Philips screws from the rear side of the
housing and lift off the lower half of the housing.
- Using the wrong fuse can result in fire. You must therefore only ever use a
fuse with the following specification:
F 200 mA / 250 V ("flink")
