• These could corrode the surface of the measuring instrument. Furthermore, the fumes are hazardous to your
health and 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, lint-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 with replacement:
• Separate the connected measuring leads from the measuring circuit and the
measuring device.
• Switch the digital multimeter off.
• Unscrew the screws on the battery cover, carefully remove the battery cover and
battery.
• Unscrew the two screws on the back of the device and carefully pull the casing apart.
• 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, fast-acting, 0.6 A/600 V (6 x 32 mm)
•
F2 fine-wire fuse, fast-acting, 10 A/600 V (6 x 25 mm)
• 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!
The operation of the digital multimeter requires a 9 V block battery. You need to insert a battery prior to initial operation
(included in the delivery). Exchange the battery if the battery change symbol
appears on the LC display (4). The
battery voltage is below <7.6 V in that case. If the battery voltage is insufficient, inaccurate/incorrect readings are
likely to occur!
