2. Short-circuit the cable ends with each other as shown in Fig. 5 making sure that the

metallic parts of test probes and crocodiles are in good touch

Press GO to perform the measurement

MODE

PEAK

Press and hold ZERO key for 2s. The instrument resets the resistance of the

cables, the symbol ZERO is displayed

5. The measured value is stored by the instrument and used as offset (which means it’s

deducted from all continuity tests performed) until a new pressing of the ZERO key for

2s that voids the calibration

6. Each time the instrument is switched off or changing position of selector, the

calibrated value is lost

4.4.2. Anomalous cases which may occur during  measurement

1. The full scale of the instrument is

199.9. If the resistance value is higher

than this value, or in case of open or

interrupted probes, the instrument

displays the screen beside.

2. If the voltage present at the terminals is

higher than 24V the instrument does not

perform the test. The screen beside is

displayed
