Do not use any carbon-containing cleaning agents or petrol, alcohol or the like to
clean the product. These could corrode the surface of the measuring instrument.
The fumes are furthermore a health hazard and are explosive. Moreover, you
should not use sharp-edged tools, screwdrivers or metal brushes or similar for
cleaning.
For cleaning the device or the display and the measuring lines, use a clean, fuzz-
free, antistatic slightly damp cloth.
Inserting/changing the batteries
Operation of the measuring device requires a 9V battery (e.g. 1604A). You need to
insert a new, charged battery prior to initial operation or when the battery change
symbol appears on the display.
To insert/replace the battery, proceed as follows:
- Separate the connected measuring leads from the measuring circuit and the
measuring device. Switch off the measuring device.
- Loosen the two screws on the rear of the battery compartment and remove the
battery compartment lid.
- Connect a new battery with the battery clip in the DMM observing the right polar-
ity.
- Now, close the cover carefully again.
Never operate the measurement device when it is open. !RISK
OF FATAL INJURY!
Do not leave flat batteries in the device. Even batteries protect-
ed against leaking can corrode and thus release chemicals
which may be detrimental to your health or destroy the battery
compartment.
Do not leave batteries lying around carelessly. They might be
swallowed by children or pets. If swallowed, consult a doctor
immediately.
Remove the batteries if the device is not used for longer periods
of time to prevent leaking.
