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.

PRESENTATION

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.
