2. DESCRIPTION
This multimeter is one of the ASYC II (Advanced SafetY Concept, second generation) range,
designed for a high degree of user safety, maximum protection and unrivalled performance.
2.1. Selector
switch
This standalone, handheld professional measuring instrument is capable of measuring the
following quantities (accessed by the eight-position rotary selector switch) :
AC voltages with AC (or RMS) capacitive coupling
AC voltages with AC+DC (or TRMS) direct coupling
DC
voltages
AC currents with AC (or RMS) capacitive coupling
AC currents with AC+DC (or TRMS) direct coupling

2.2. Keypad
An nine-key keypad lets you :
select the autoranging mode (RANGE)
store a value (HOLD)
measure fast peaks (PK+/-)
set
the
measurement
relative to a reference value (REL)
select a function derived from the main function, or switch on the multimeter again after it
has been shut down automatically (SEL/ON)
select time-domain measurements: frequency, duty cycle, stopwatch, pulse counter (Hz)
activate the MIN- MAX- AVG detection mode (SURV)
activate sending data to a printer or a computer (PRINT)
2.3. Display
The display shows :
clearly legible figures (14 mm high)
an analogue readout of the parameter being measured through a 34-segment bargraph
perform 50 000-point measurements (high resolution)
perform 5 000-point measurements (low resolution)
2.4. Power
supply
It is powered by a standard 9 V (6LF22, 6LR61) battery which provides approximately 300 hours
of operation (in VDC mode). It is prohibited to use batteries other than those specified (see §.
3.5.3. Replacing the battery or fuse).
2.5. Input
terminals
Measurements are performed using two measuring leads supplied with the instrument
connected to input terminals 1, 2, 3 and 4, as indicated in §. 3.1.
