6 Intended use

Measures and displays electrical parameters in measurement category CAT III
(up to 600 V).
Complies with the EN 61010-1 and EN 61010-2-033 standards and all lower
categories.
Measures direct and alternating voltages up to 600 V
Measures direct and alternating currents up to 10 A
Measures frequency from 10 Hz to 10 MHz (max. 20 Vrms)
Measures capacitance up to 40 mF
Measures resistances up to 40 MΩ
Continuity tests (<10 Ω acoustic)
Diode tests
The measuring mode can be selected using the control dial. The measurement
range is selected automatically in most modes (except continuity test, diode test
and current measuring mode).
Effective (True RMS) measurements are displayed when measuring AC voltages/
currents with a frequency of up to 400 Hz. This ensures that sinusoidal and non-
sinusoidal voltage/currents are measured accurately.
Negative polarity readings are indicated with the (-) sign.
The multimeter features a low-impedance function (LoZ) that enables you to meas-
ure the voltage with reduced internal resistance. This suppresses phantom voltages
that may appear in high-impedance measurements. The low-impedance function
must only be used to measure circuits of up to 250 V for a maximum of 3 seconds.
The two current measurement inputs are protected against overload. The voltage in
the measuring circuit must not exceed 600 V.
The 10 A current measuring input is equipped with a ceramic high-performance fuse.
The mA/µA measurement input is equipped with 2x maintenance-free self-resetting
PTC fuse and one ceramic tube fuse, which can be used in the case of conventional
overload misoperation of less than about 5A, the current is limited and the meter
is well protected. When the meter is being used for mA/µA measurement, but the
meter is mistakenly connected to a high-energy high-voltage power supply, then the
