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

TO ORDER
DMM 121 ................................................... P06231421Z
POWER SUPPLY
Battery: 2x1.5V AA/LR6
Mean battery life: ~400 hours
Auto power off delay: After 30 minutes without action on
the keys and/or on the switch.
COMPLIANCE WITH INTERNATIONAL STANDARDS
Compliant with standards IEC 61010-1 and IEC 61010-
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.
