Insert the new battery into the battery compartment and close it carefully.
Make sure that the lead (red/black) of the terminal clip is not kinked.
Warning!
Never operate the measuring instrument when it is open.
!Danger to life!
Do not leave used batteries in the instrument since even
leakage-protected batteries can corrode releasing chemical
agents that might harm your health or destroy the battery
compartment.
Batteries should be considered to be special waste and,
therefore, should not be disposed of in an environmentally
compatible way (collecting boxes).
Replacing the fuse
As soon as the built-in fine-wire fuse (5 x 20mm) has reacted, any further mea-
suring becomes impossible.
Instead of a measured value, only "FUSE” will be displayed and you will hear
an acoustic signal (for about 2 sec.). The fuse must be replaced.
Proceed as follows:
When replacing the fuse you should absolutely observe the safety instruc-
tions! You must make sure that you use only fuses of the indicated type
and nominal value. Using repaired fuses or bridging the fuse holder is inad-
missible. For replacing the fuse, disconnect the measuring device from the
measuring circuit and switch if off. Remove any leads, adapters and test
pivots. Take a suitable screwdriver and open the housing carefully.
Remove the holster and battery compartment first, then remove the two
remaining recessed-head screws. Then lever out the lower housing half-
shell: the fuse is free. Remove the defective fuse and replace it by one of
the same type and nominal value. (See overload protection, max. input val-
ues)
Warning!
Carefully close the housing and screw it home in the oppo-
site order. Only take the measuring instrument into opera-
tion when the housing is closed correctly and the screws
are securely tightened.

- For your own safety you should absolutely avoid that the measuring instru-
ment or the leads get humid or wet.
- Only use the enclosed measuring leads for measuring. Only these are
admissible.
- To avoid an electric shock, please make sure not to touch (not even indi-
rectly) the measuring pivots and the measuring connections (measuring
points) during the measurement.
- If there is cause to believe that a safe operation has become impossible,
put the instrument out of operation and secure it against any unintended
operation. Safe operation must be presumed to be no longer possible, if
- the instrument exhibits visible damage
- the instrument does not operate any longer
- the instrument was stored under unfavourable conditions for a long peri-
od of time.or
- the instrument was exposed to extraordinary stress caused by transport
- Never turn on the instrument immediately after it has been brought from a
cold into a warm room. Condensation water that forms might destroy your
instrument or lead to false measurements. Leave the device switched off
and wait until it has reached room temperature.
Presentation
With this L C R measuring instrument, you are able to carry out extensive
measurements on voltage-free components such as resistors in the range of
0 to 10 MOhm, capacitors in the range of a few pF up to 20000 µF and induc-
tors in the range of a few mH up to 20000 H. The multi-function display with a
large and a smaller display, each with 4
1
/
2
digits, allows very easy readings.
The internally generated measuring frequency for measuring capacitors and
inductors is approximately 120 Hz / 1 kHz (reversible). With a serial infrared
interface (bi-directional) you can communicate with your PC after having con-
nected the interface lead and having installed the software.
The measuring instrument is universally applicable in school, hobby and pro-
fessional workshops etc.
