3-4 Ω RESISTANCE MEASUREMENT
Zero adjustment on the ohmmeter is carried out using the calibration button (front) by
short-circuiting the inputs.

(1) Buzzer for R ≤ 100, no buzzer for R ≥ 250Ω
(2) of the mid-scale value
(3) for 5 seconds (protection by Resistances and CTP)
(4) for battery voltage of 1.45V ± 0.1V
3-4-1 AUDIBLE CONTINUITY TEST - SEMI-CONDUCTOR TEST
NB : In Ω x 1: "buzzer" threshold ≤ 250Ω, control of diode on or blocked (
in "COM" for on). Do not carry out live measurements.
On the ohmmeter, calibre Ω x 1, if voltage of V
issues a modulated sound until the error has been corrected.
