Ferm

stinking insulation.

8.  Use your multimeter, only if it is closed.

6. GUARANTEE CONDITIONS

1.  Ferm has thoroughly proved this product and vou-

ches for the good quality of manufacturing and
material. Ferm grants a 

12 MONTHS

guarantee,

from the date of purchase, covering every material
and production fault, that might occur. Any other
kind of claim on compensation, direct or indirect,
to persons and/or materials, will be rejected.

2.  First, consult your Ferm dealer. Usually, your

dealer will be able to eliminate the problem or the
failure.

3.  The term of guarantee cannot be extended, by

repairing or replacing parts within the guarantee
period.

4.  Normal wearing will not be covered by the guar-

antee; e.g. switches are not covered and also
damage due to out-of-range measurements. 

5. YOUR RIGHT ON GUARANTEE WILL

ONLY BE VALID IF:

- a proof of the date of purchase can be shown, in

the form of a 

PURCHASE RECEIPT

;

- the associated guarantee certificate has been

signed and filled in completely;

- neither third parties have carried out any

repair or modification on the device, nor any
non-original part has been assembled;

- the device has been treated, according to the

operation instructions;

- there are no circumstances beyond our control.

6.  The guarantee conditions will apply in conjunction

with our terms of delivery and conditions of sale.

7.  The transport costs of the device to be repaired

will come to the account of the buyer. Badly wrap-
ped articles will be rejected.

8.  The guarantee certificate is enclosed in the back of

this manual.

7. ENVIRONMENTAL PROTECTION

Regaining of resources is better than wasting them!
Your device must be delivered in a solid wrapping, to
avoid damage due to transport. This wrapping has
been made of recyclable material, such as paper, card-
board and wood. We recommend to recycle the
wrapping as much as possible. 

Your multimeter contains a battery.
Never waste this battery when it got
empty, but hand it in as "Small Che-
mical Waste". 

For replacement of the battery, refer to chapter 13
"Replacing the battery".

8. FERM AFTER-SALES SERVICE

Keep the original wrapping. Using this original wrap-
ping will minimize the probability of transport damage,
if your device still has to be transported. In case of a
guarantee claim, your device must be presented in the
strongest possible wrapping, preferably the original
one. Each Ferm product has been proved with utmost
accuracy, before leaving the factory. Consult your
Ferm dealer, if your device still gets out of order.

9. BEFORE USING YOUR DEVICE

1.  Set the turning knob to the highest range, if you do

not know the voltage and/or current to be meas-
ured. Adjust the turning knob one measuring-ran-
ge lower and so on, if the accuracy is not enough.

2.  Set the turning knob to OFF, if you do not use your

device.

3.  The difference between the measurement of vol-

tage and current is based on the circuit of your
multimeter: Parallel for voltage and in series for
current measurements. In the latter case, a con-
ductor will have to be interrupted.

4. Never connect a source or charge to your multi-

meter, with the FUNCTION-switch in 

or

position.

5.  Never connect a voltage over 1000 VDC or 700

VAC rms to your multimeter.

10. OPERATION 

SEE FIG. 1

A. LCD display. Large 3 1/2 digit display, with a read-

out upto 1999. Indications for decimal point, pola-
rity, overload and empty battery.

B.  Range switch. Rotary switch to set the range.
C. 20A. Positive connector for measuring currents

above 200 mA upto 20A.

D. mA. Positive connector for the measurement of

currents upto 200 mA.

E.  COM. Negative connector
F. V/

. Positive connector for voltage and resistance

measurements.

11. MEASURING

11.1 Measuring direct voltage (VDC)

1. Connect 

the 

BLACK

cord to the 

"COM"

-con-

nector and the 

RED

cord to the 

V/

-connector.

2. Set the 

FUNCTION

-switch to the desired

“V

position and put the cords over the

respective source or charge. Mind the correct
polarity (red is +, black is -), otherwise the display
will show a minus-sign before the value.

3.  Readout the value in Volt.
