Frequently asked questions

The instrument may only be used in power installations if the electrical circuit is protected with a fuse or a circuit breaker with a rating of up to 20 A, and if nominal voltage at the system does not exceed 240 V~ (AC) or 50 V (DC).

The maximum allowable voltage between terminals (3), (4), (5), (6) and ground is equal to 300 V, category II. The current measuring range A is equipped with a magnetic circuit breaker. Max. allowable voltage at the meas. circuit (= miniature circuit breaker nominal voltage) is equal to 240 V~ (AC) and 50 V (DC) against earth in the “mA” and “A” ranges.

Connect the measurement cables to the instrument and connect the free ends to one another (short circuit the test probes). Briefly press the FUNC key. The instrument acknowledges zero balancing with an acoustic signal, and “00.00 ”, “000.00 ” or “0.0000 k”and the ZERO symbol appear at the LCD. Resistance measured at the moment the key is pressed is used as a reference value (max. 2000 digits). This value is automatically subtracted from all subsequently measured values.

The smallest measurable frequencies and maximum allowable voltages are listed in chapter 15, “Characteristic Values”. The pulse-period ratio can be ascertained for square-wave signals with the duty cycle measurement.
