• • • • • • • Voltage measurement may only be performed with the selector switch set to the V= or the V~ position. Be prepared for the occurrence of unexpected voltages at devices under test (e.g. defective devices). For example, capacitors may be dangerously charged. Make certain that the measurement cables are in flawless condition, e.g. no damage to insulation, no interruptions in cables or plugs etc.
2 Initial Start-Up Battery Your instrument is supplied with two 1,5 V AA size batteries in accordance with IEC LR 6, and is ready for operation. Be sure to refer to chapter 15.1 “Battery”, before initial start-up, or after your device has been in storage for a lengthy period of time. Switching the Instrument On ➭ Press the ON / OFF key. Power-up is acknowledged with an acoustic signal. All of the segments at the liquid crystal display (LCD) are illuminated shortly.
3.4 Relative Measurement REL A reference value for relative measurements can be stored to memory with the keys MAN / AUTO and HOLD. The applicable reference or correction value is substracted individually for the respective measuring function as an offset from all subsequent measurements, and remains in memory until deleted, or until the multimeter is switched off. Reference value setting is only possible for the respective manually selected measuring range.
Voltage Measurement ➭ Depending upon the voltage to be measured, set the rotary selector switch to V or V . Connect the measurement cables as shown. The “” connector jack should be grounded. ➭ Note! The 600 mV measuring range can only be selected manually with the MAN / AUTO key. If the measured value exceeds 60 V DC or 40 V AC the symbol appears at the display. An intermittent acoustic signal warns the operator if the measured value exceeds the upper range limit value of 1000 V in the 1000 V range.
➭ ➭ ➭ ➭ Current Measurement First disconnect supply power from the measuring circuit or the consuming device, and discharge any included capacitors. Select the A range with the rotary selector switch for current greater than 600 mA, or the mA range for current less than 600 mA. Activate the highest measuring range first when measuring current of an unknown magnitude. Select the current type appropriate for the measured quantity by briefly pressing the FUNC key.

If a fuse blows, eliminate the cause of overload before placing the instrument back into service! Refer to chapter 15 “Maintenance”, regarding fuse replacement.
8.1 Measuring Alternating Current with (Clip-On) Current Transformers 8.1.1 Transformer Output mA / A ! Attention! If current transformers are operated without being connected at the secondary side (e.g. as a result of defective or missing cables, a blown device fuse or incorrect connection), dangerously high voltages may occur at the connector jacks.
10 ➭ ➭ ➭ Continuity and Diode Testing Make sure that the device under test is voltage-free. Interference voltages distort measurement results! Set the rotary selector switch to . Connect the device under test as shown. 0.000 FUNC brief 030.
11 ➭ ➭ ➭ Capacitance Measurement Make sure that the device under test is voltage-free. Interference voltages distort measurement results! Turn the rotary switch to the “F” position. Connect the (discharged!) device under test to the and V jacks with the measurement cables Note! The “–“ pole of polarized capacitors must be connected to the „“ jack. Resistors and semiconductor paths connected in parallel to the capacitor distort measurement results! F 00.
Temperature Measurement The multimeter provides for the measurement of temperatures within a range of – 50°C to + 800°C with the help of a type K temperature sensor. ➭ Set the rotary selector switch to „°C“. ➭ Connect the sensor to the two accessible jacks. The device indicates the measured temperature in C at the digital display. ➭ Briefly press the FUNC key to switch between C and F.

15 Maintenance ! Attention! Disconnect the instrument from the measuring circuit before opening to replace batteries or fuses! 15.1 Battery Make sure that no battery leakage has occurred before initial start-up, and after long periods of storage. Continue to inspect the batteries for leakage at short, regular intervals. If battery leakage has occurred, carefully and completely clean the electrolyte from the instrument with a damp cloth, and replace the batteries before using the instrument.
