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.
