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
It is a standalone, handheld professional measuring instrument, capable of measuring the
following quantities (accessed by the eleven-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,
∗ DC currents,
∗ resistance values,
∗ continuity (with beeper),
∗ capacitance,
∗ diode threshold voltage,
∗ frequencies,
∗ duty cycles
2.2.
Keypad
A six-key keypad lets you :
∗ select the autoranging mode (RANGE key),
∗ store a value (HOLD key),
∗ measure fast peaks (Pk +/- key),
∗ set the measurement relative to a reference value (REL key),
∗ select a function derived from the main function, or switch on the multimeter again
after it has been shut down automatically (SEL/ON key),
∗ activate sending data to a printer (PRINT key).
2.3.
Display
The display provides :
∗ 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
This multimeter is powered by a standard 9 V battery which provides approximately
500 hours of operation.
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 section 3.1.
