DESCRIPTION

This compact multimeter is a self-contained with an appropriate mechanical construction,
enables hand-held version, with a protective elastomer case.
It is designed for a high degree of user safety, maximum protection and unrivalled
performance.
2.1.

Selector switch

This multimeter is a standalone, hand-held professional measuring instrument, capable of
measuring the following quantities (accessed by the twelve-position rotary selector switch) :
∗ AC voltages with AC (or RMS) capacitive coupling (Input impedance : 500
∗ AC voltages with AC+DC (or TRMS) direct coupling
∗ DC voltages
∗ DC / AC+DC voltages, range 500 mV
∗ AC currents with AC+DC (or TRMS) direct coupling
∗ DC currents
∗ resistance values
∗ continuity (with beeper)
∗ capacitance
∗ diode threshold voltage
∗ frequencies
2.2.

Keypad

A four-key keypad lets you :
∗ select the autoranging mode (RANGE / AC+DC key)
∗ store a value (MEM key)
∗ activate the MIN-MAX-AVG detection mode (MIN/MAX key)
∗ select a function derived from the main function, or switch on the multimeter again
after it has been shut down automatically (RANGE / AC+DC key)
∗ activate back lighting of the display unit (
2.3.

Display

This multimeter display provides :
∗ perform 5 000-count measurements (50 000-count Hz-measurement),
∗ function indicator (V, A, AC+DC, F, Hz,
and multiplicator (n, µ, m, k, M),
∗ battery discharged indicator BAT : approximately 12 hours of operation,
∗ clearly legible figures (11 mm high),
∗ an analogue readout of the parameter being measured through a 34-segment
bargraph.
Display back light when required in poor lighting conditions. automatic switch-off.
2.4.

Power supply

This multimeter is powered by a standard 9 V battery (6LF22) which provides
approximately 500 hours of operation (on function V

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.
