You have just purchased a DMM121 digital multimeter

and p1-we thank you for your conﬁdence.

For best results from your instrument:

read these operating instructions carefully,

comply with the precautions for use.

PRECAUTIONS FOR USE

This instrument and accessories are compliant with

safety standards IEC 61010-1, IEC 61010-031 and

IEC 61010-2-033 for voltages up to 600V in category III.

Failure to observe the precautions for use and safety

instructions may cause an electric shock, ﬁre, explosion,

or destruction of the instrument and of the installations.

The operator and/or the responsible authority must

carefully read and clearly understand the various

precautions to be taken in use.

If you use this instrument other than as speciﬁed, the

protection it provides may be compromised, thereby

endangering you.

Do not use the instrument on networks of which the

voltage or category exceeds those mentioned.

Observe the environmental conditions of use.

Do not exceed the rated maximum voltages and

currents between terminals or with respect to earth.

Do not use the instrument if it seems to be damaged,

incomplete, or poorly closed.

Before each use, check the condition of the insulation

on the leads, housing, and accessories. Any item of

which the insulation is deteriorated (even partially) must

be set aside for repair or scrapping.

Use only the leads and accessories supplied. Using

leads (or accessories) of a lower voltage or category

reduces the voltage or category of the combined

instrument + leads (or accessories) to that of the leads

(or accessories).

Use personal protective equipment when conditions

require.

When handling the leads, test probes, and crocodile

clips, keep your ﬁngers behind the physical guard.

Keep your hands away from the terminals of the

instrument.

Replace the battery as soon as the symbol appears

on the display unit. Disconnect all leads before opening

the battery compartment cover.

HZ AND % FUNCTIONS

For AC voltage and current measurements, they are used

to display the frequency and the duty cycle of the signal

measured, respectively.

REL FUNCTIOND

The REL key is used to subtract the value displayed D

at the time the key is pressed from all subsequent

measurements values and to display the result of the

subtraction. This function is not available when “OL” is

displayed.



The automatic power down function of the device is

reactivated when the device is switched back on.

CHANGING MODES

Several modes may be available for a given function

(existence of additional modes indicated by a yellow

symbol). Press the SELECT key to change which mode

is active.

For safety reasons this fuse must always be

replaced by an identical model:

F1: 10x38, type FF, 10A/600V

F2: 6.3x32, type FF, 630mA/600V

When the current measured exceeds the rating of the

fuse, the fuse may blow.

REPAIR

Return the instrument to your distributor for any work to

be done, whether under the warranty or not.

If you have to ship the instrument, it is best to use its

original packaging and to state as clearly as possible,

in a note attached to the equipment, the reasons for the

transfer.

WARRANTY

The equipment is warranted against defects of materials

or workmanship, in accordance with the general terms

of sale.

During the warranty period (1 year), the instrument must

be repaired only by the manufacturer, who reserves

the right to choose between repairing it or replacing it,

entirely or partially.

If the equipment is sent back to the manufacturer,

carriage is paid by the customer.

The warranty does not apply in the following cases:

Inappropriate use of the equipment or use with

incompatible equipment;

Modiﬁcations made to the equipment without the

explicit permission of the manufacturer’s technical

staff;

Work done on the device by a person not approved

by the manufacturer;

Adaptation to a particular application not anticipated

in the deﬁnition of the equipment or not indicated in

the user’s manual;

Damage caused by shocks, falls, or ﬂoods.

2-033 for 600V CAT III installations.

Maximum input voltage: 600V between terminals.

ELECTROMAGNETIC COMPATIBILITY

Emissions and immunity in an industrial environment

per EN 61326-1.

MAINTENANCE

Except for the fuse and the batteries, the

instrument contains no parts that can be replaced by

personnel who have not been specially trained and

accredited. Any unauthorized repair or replacement of a

part by an “equivalent” may gravely impair safety.

CLEANING

Disconnect the unit completely and turn the rotary switch

to OFF.

Use a soft cloth, dampened with soapy water. Rinse with

a damp cloth and dry rapidly with a dry cloth or forced

air. Do not use alcohol, solvents, or hydrocarbons.

REPLACEMENT OF THE BATTERIES

The symbol indicates that the batteries are dead and

must be replaced.

To replace the batteries, proceed as follows:

Disconnect the unit completely and turn the rotary

switch to OFF;

Remove the jacket;

Unscrew and remove the 4 battery compartment

cover screws;

Remove the old batteries and insert the new ones,

with the polarities as indicated.

Spent batteries must not be treated as ordinary

household waste. Take them to the appropriate

recycling collection point.

REPLACING THE FUSE

When the measurement current exceeds the current

rating of the fuse, the protection fuse may blow.
