For cleaning the device or the display and the measuring lines, use a clean, fuzz-free, antistatic
slightly damp cloth.
c) Fuse replacement
Using mended fuses or bridging the fuse holder is not admissible for safety reasons.
Never operate the measurement device when it is open.
RISK OF FATAL INJURY!
The currency measuring ranges are protected against overload with ceramic fine-wire fuses. If
measuring in this range is no longer possible, you have to change the fuse.
Proceed as follows for replacement
1. Separate the connected measuring leads from the measuring circuit and the measuring device.
2. Switch the DMM off.
3. Unscrew the screws on the battery cover, carefully remove the battery cover and battery.
4. Unscrew the two screws on the back of the device and carefully pull the casing apart.
5. Replace the defective fuse with a new fuse of the same type and nominal voltage. The fuses have
the following values:
- F1 fine-wire fuse, quick-action, 0.5 A/600 V (6 x 32 mm), Item no.: 702632.
- F2 fine-wire fuse, quick-action, 10 A/600 V (6 x 25 mm), Item no.: 700161.
6. Now close the housing carefully again.
d) Inserting/replacing the battery
Do not leave flat batteries in the device. Even batteries protected 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.
If the device is not used for longer periods of time, remove the batteries in order
to prevent leaking.
Leaking or damaged batteries might cause acid burns when getting into contact
with skin. Therefore, use suitable protective gloves.
Make sure that the batteries are not short-circuited. Do not throw batteries into fire!
Batteries may not be recharged. Danger of explosion!
Operation of the measuring device requires a 9 V battery (e.g. 1604A). You need to insert a new, charged
battery prior to initial operation or when the battery change symbol
38
appears on the display.
