3.3 Audio continuity test (

1. Connect the measuring leads to the instrument's terminals.
2. Set the selector switch to the "
3. Connect the instrument to the circuit to be tested. The
buzzer is permanently active as soon as contact is
established (circuit closed) and if the value of the resistance
measured is less than the value of the threshold chosen
by programming (can be set from 1 to 40 Ω, see § 3.8.11)
Above 400 Ω, the display indicates " OL ".
Offset of measurement lead resistance (zero Ω Ω Ω Ω Ω )
To measure low-value resistance, first measure the
resistance of the leads.
- Short-circuit the leads.
- Press on the HOLD key and hold down until zero is
displayed. The value of the resistance of the leads will
then be saved and deducted from the value of the
resistance subsequently measured.
Note: If the value measured is over 2 Ω , this correction is
inhibited and the value of the correction saved is
reset to zero.
