PRECAUTIONS FOR USE
This device complies with safety standards IEC/EN 61010-1 or BS EN 61010-1 and IEC/EN 61010-2-032 or BS EN 61010-2-032
for voltages of 1 000 V in category IV and 1 500 V in category III, less than 2 000 m, indoors, with a degree of pollution not
exceeding 2.
These safety instructions are intended to ensure the safety of persons and proper operation of the device. If the tester is used
other than as specied in this data sheet, the protection provided by the device may be impaired.
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 specied, the protection it provides may be compromised, thereby endangering you.
Do not use the instrument in an explosive atmosphere or in the presence of ammable 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 and currents between terminals or with respect to earth.
Do not use the instrument if it appears to be damaged, incomplete, or not properly closed.
Before each use, check the condition of the insulation on the leads, housing, and accessories. Any element of which the
insulation is deteriorated (even partially) must be set aside for repair or scrapped.
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 lowers the category of the combined Clamp + accessory to that of the accessory.
Observe the environmental conditions of use.
Do not modify the instrument and do not replace components with "equivalents". Repairs and adjustments must be done by
approved qualied personnel.
Replace the batteries as soon as the symbol appears on the display unit. Disconnect all cords before opening the
battery compartment cover.
Use personal protective equipment when conditions require.
Keep your hands away from the unused terminals of the instrument.
When handling the test probes, crocodile clips, and clamp ammeters, keep your ngers behind the physical guard.
As a safety measure, and to avoid repeated overloads on the inputs of the device, we recommend performing conguration
operations only when the device is disconnected from all dangerous voltages.

3. THE KEYS
The keys of the keypad respond di󰀨erently to short, long, and sustained presses.
The
MAX/MIN
, Hz and ∆REL keys provide new functions and allow the detection and acquisition of parameters complementary
to the usual elementary measurements.
Each of these keys can be used independently of the others or in perfect complementarity with them: this makes
navigation simple and intuitive for looking up all measurement results.
It is possible, for example, to look up in turn the MAX, MIN, etc. values of the RMS voltage only, then display relative
values in parallel.
In this section, the icon represents the possible positions of the switch for which the key concerned has some action.
3.1. HOLD KEY
This key is used to:
store and look up the last values acquired specic to each function (V, A, Ω, T°, Adp) according to the specic modes previously
activated (MAX/MIN, Hz, ΔREL); the present display is then maintained while the detection and acquisition of new values
continues;
perform automatic compensation of the resistance of the leads (see also § 4.6.1);
perform an automatic zero correction in ADC (see also § 4.9.2).
Successive presses on HOLD ... serve
short
1. to stored the results of the present measurements,
2. to hold the display of the last value displayed,
3. to return to normal display mode (the value of each new
measurement is displayed)
long (> 2 sec) ADC
to perform automatic compensation of the zero (see § 4.9.2)
Remark: this mode operates if the MAX/MIN or HOLD modes
(short press) are rst desactivated.
sustained to perform automatic compensation of the resistance of the
leads (see § 4.6.1)
See also § 3.4.2 and § 3.5.2 for the action HOLD key with the action of the
MAX/MIN
key and with the action of the Hz key.
