PRECAUTIONS F OR USE

This device is compliant with safety standards IEC61010-1, 61010-2-032 and 61010-2-033 for
voltages up to 300V in category III at an altitude below 2,000m, indoors, with a degree of pollution
of not more than 2.
These safety instructions are intended to ensure the safety of persons and proper
operat ion of the dev ice. If t he device is used othe r than as spec ified in t his data s he et, the
protec tion provided by the de vice may be i mpaired.
 The opera tor and/o r the res po nsible aut ho rity must carefully read and c learly

underst and the va rious prec autions to be taken i n use.

 If you use this ins t rument othe r than as s pe cified, t he protec tion it prov ides may be

compromi s ed, ther eby endanger ing you.

 Do not use the instrument in an explosive atmosphere or in the presence o f

flammable gases or fumes.

 Do not use the instrument on networks of which the voltage or category exceeds

those mentioned.

 Do not exceed the rated maximum voltages between terminals or with respect to

earth.

 Do not us e the instrument if it seems to be damaged, incomplete, or poorly closed.
 Before eac h use, c hec k the co nditi on o f the ins ulatio n on t he le ads , hous ing, a nd

accesso ri es. Any ite m of whi ch t he i nsula ti on is dete rio rate d (e ven pa rti ally ) must
be set aside for repair or scrapping.

 Use leads and accessories rated for voltages and categories at least equal to

those of the instrument. If not, an accessory of a lower category reduces the
category of the combined multimeter + accessory to that of the accessory.

 Observe the environmental conditions of use.
 Do not modify the instrument and do not replace components with "equivalents".

Repair s and adjust me nt s must be done by appr o ved quali f ied pers onnel.

 Replace the battery as soon as the

symbo l appe ars on t he dis play unit .

Disconne ct all leads before opening the battery compartment cover.

 Use pers onal protec tive equipment when co nditions require .
 Keep your hands awa y from the unus ed test pr obes of the device.
 When handli ng the te st probes, crocodile clips, and c urrent sens or, keep yo ur

fingers behind the p hysica l gua rd.

 Disconnect the test probes from the measurement circuit to make current

measurements.

 Disconnect the test probes from the measurement circuit before changing

functio ns.

-"HOLD " key

In the "HOLD" mode, the device freezes the display of the last value measured.
 Pressi ng the "HOLD" ke y brief ly during a me a surement freezes the display: the

message

is the n di splayed.

 A second brief press on the "HOLD" key is used to return to the normal measured

value di s play refr esh mode: the messa ge

disappears from the di splay uni t .

-"MAX MIN" key

In the "MAX MI N" mode, the device records the maximum and minimum values of the
measurements made. In this mode , the auto matic range change does not c hange the
range when this mode is entered; if the maximum values exceed the display range
(indicated by the "OL" message), the appropriate hi ghe r r a nge must be c ho s e n manua l ly
before reactivating the "MAX MIN" mode.
Succes s i ve brief presses on t he "MAX MIN" ke y produce , in orde r , the follo w ing actio ns:
 1st press : the device re cords and displa ys the maximum va lue measured. The

"AUTO" message is replaced by "MANU" and the "MAX" message is displayed.

 2nd pres s : the de vi ce r ec o rds a nd di s pla y s the mini mum value mea s ure d; the " M AX "

message is replace d by "MIN".

 3rd press: the device records the maximum and minimum values measured

simultaneously; it is the va lue curr ently meas ured tha t is displa yed; the "MAX" and
"MIN" mes s ages blink s imultane ously on the display unit.

 Additio nal press es serve to display the values rec orded one by one by re producing t he

actions of the prev ious succ essive pres ses.
Press the "MAX MIN" key for two seconds to exit from the mode: the "MANU", "MAX",
and "MIN" messages are replaced by "AUTO", indicating that the device once again
changes range auto matically.

-"Hz" ( Hertz ) key

Press the "Hz" key briefly and repeatedly to obta in t he fo llow ing func ti ons acco rdi ng to

not reactivated, the backlighting switches itself off automatically after approximately 60
seconds .

"REL (ZERO)" key

The "REL (ZERO)" key is used to subtract the value displayed when the key is pressed
from all su bsequent measureme nt values a nd display the res ult of the subt raction.
This mode can be activated by a brief press on the key for all functions except the
frequenc y and duty c ycle meas urements.
When dis play in re lative mode is activate d, the auto matic range cha nge leav es the range
unchanged when the mode is entered: the device changes to manual range change

mode and the "MANU" and "

" messa ges are displa yed.
For DC current measurements, this mode is used to set the display to zero before the
current senso r is pla ced on t he conduc tor in whic h the c urrent is to be measur ed; the
message displaye d for this function, i n this mode, i s "ZERO".
Another brief press on the key effects the return to the normal displa y mode ; the dev ic e

returns to t he a uto mat i c ra nge c ha nge mo de and t he "MAN U" a nd "

1.4 The leads and t est pr ob es

The multimeter is equipped with two leads (red and black), each terminated by a test
probe of the same colour.
The leads and test probes are not detachable (they are permanently connected) and,
when not i n us e, c a n be s to we d i n the c o mpar tme nts pr o v i ded f o r t he m on t he ri g ht s ide
of the dev ice.
The tips of the test probes (once taken out of their compartments by pressing on them
with a finger), allow volta ge, resi stance, continuit y, diode test, and c apacita nce
measurements.
The test probes have physical guards that show the operator where the hand grip part
ends, bey ond which t he fingers must not be placed.

1.5 The current sensor

The multimeter has a current sensor that makes it possible to measure a current without
having to open the ci rcuit.

2. US E

2.1 Commissioning

Place t he batterie s supplied wi th the dev ice as follo ws:

1. Using a cross-headed screwdriver, unscrew the screw of the compartment cover
on the bac k of the hous ing and open t he cover;

2. Place the 2 batteries in their compartment, with the correct polarities;

3. Clo se the cov er and scre w it back t o t he housi ng.

2.2 Starting up and check of operation

We reco mmend perfo rming this procedure at the t ime of commi s sioni ng and, if the devic e
is used only occasio nally, e ac h time it is used.
 Hold the " HOLD" key down and s w itch the instrument o n by turni ng the switch fro m

"OFF" to "Ω".

 Release the "Hold" key and check that the various symbols and segments are

correc tly display ed.

 A brief press on the "HOLD" key restores the normal display of the selected

functio n;

 If the device is set to the resistance measurement function ("Ω"), che ck tha t the

display indicates "A.P.O" (for auto power off), "AUTO" (for automatic range
change), "O.L" (for OverLoad), and "MΩ" (for Megohm);

 Withdraw the two leads from their compartment and establish a good contact

between the metallic parts of the two test probes; the value measured and
displayed must cha nge from "O.LMΩ" to "0.0Ω": (the va lue display ed may not
be exactly zero, but must remain very close to zero).

 The instrument is operational when the various states described above have been

checke d and are co rre c t. The r ot a ry s witc h c a n t hen be s et t o the de si r ed f unc t i on
or to "OFF" to switch the instrument off.
