3. USE 3.1. CHECKING THE OPERATION OF THE INSTRUMENT Before making any use of the instrument, check that it is operating correctly. „ Make a voltage measurement on a known voltage. If the measurement is incorrect, do not use the instrument. „... - Page 11 10 V If the voltage is pure DC, the AC voltage reading is zero. Vdc = 10 V Vac = 0 V Vac+dc = 10 V 100 V If the voltage is mixed (AC plus DC), as in the example opposite, a DC voltage with a ripple, the AC+DC measurement gives the true value;...

Page 12: Insulation Resistance Measurement
3.3. INSULATION RESISTANCE MEASUREMENT 3.3.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE The device generates a DC test voltage between the + and COM terminals. This voltage depends on the resistance to be meas- ured: it is between U and 1.25 U when R ≥... - Page 13 3.3.4. OPERATION OF THE TEST BUTTON The TEST button is pressed to make an insulation measurement. The test voltage is generated for as long as the press is main- tained. When the button is released, the measurement stops. In the mode, simply long-press the TEST button to start the measurement, then long-press again to stop it;...
- Page 14 3.3.6. ERROR INDICATION „ If the measurement departs from the measurement range, the instrument so reports by displaying LO (if the insulation re- sistance is too low to allow generation of the voltage) or >4200MΩ (for a test voltage of 250 or 500V) or >11.00GΩ (for a test voltage of 1000V).

Page 15: Continuity Measurement
3.4. CONTINUITY MEASUREMENT 3.4.1. DESCRIPTION OF THE MEASUREMENT PRINCIPLE The instrument generates a 200mA direct current between the + and COM terminals. It then measures the voltage present between these two terminals and from it deduces the value of R = V/I. 3.4.2. - Page 16 3.4.3. COMPENSATION OF THE MEASUREMENT LEADS For best measurement accuracy, compensate the resistance of the measurement leads. To do this, short-circuit the measurement leads. The instrument displays the resistance of the leads. 250 V Ω 500 V Ω kΩ 1000 V MΩ...
- Page 17 3.4.5. ALARM The alarm is always active in continuity measurement. The instrument gives you a choice of two alarm thresholds: 1Ω or 2Ω. See §3.9. If the measurement is below the threshold, the symbol is displayed. If the measurement exceeds the threshold, the backlighting lights red and the symbol is displayed.
