CONTINUITY TEST

Warning: Before performing the test, make sure that the circuit is off and all
capacitors have been discharged.
1. Set the switch to
2. Connect the black lead to the COM terminal and the red lead to the "+"
terminal.
3. Connect the test probes or the alligator clips to the circuit or component
to be measured.
An audible signal is emitted if there is continuity (resistance value is below the
maximum threshold, see § 3.4.1) and the measured value is displayed on the
screen.

Lead Resistance Compensation

Warning: Before the compensation is executed, the MAX/MIN and HOLD modes
must be de-activated.
To perform automatic compensation of the test lead resistance, proceed as
follows:
1. Short-circuit the leads connected to the meter.
2. Hold the
value. The device measures the resistance of the leads.
3. Release the

NOTE: The correction value is stored only if it is ≤ 2Ω.
Above 2Ω, the value displayed blinks and is not stored.
