Resistance Measurement; Continuity Buzzer; Diode Testing - Monacor DMT-1020 Mode D'emploi

Overflow is again displayed with "1". With the measure-
ment or with the overflow indication the minus sign may
additionally be displayed.

4.3 Resistance measurement

Never measure a resistor when voltage is applied and
always measure it separately, otherwise the measure-
ment will be inaccurate. For this purpose, solder it out of
the circuit, if required.
Choose a suitable resistance range with the rotary switch.
With resistance measurements, test cables which are not
connected represent an infinitely high resistance. This is
displayed as overflow "1".

4.4 Continuity buzzer

However, never perform a continuity check when voltage
is applied, otherwise the measurement will be inaccurate.
The switch position buzzer
nuity and contact resistance. With values less than approx.
100 Ω the continuity buzzer will sound.

4.5 Diode testing

Never measure a diode when voltage is applied and
always measure it separately, otherwise the measure-
ment will be inaccurate. For this purpose, solder the
diode out of the circuit, if required.
Choose the position
the test tips at the diode in forward direction, the diode for-
ward voltage is shown. The positive pole of the measuring
voltage thereby is at the red measuring cable. The display will
show the forward voltage up to 2 V at a test current of 1 mA.
With 0 V displayed, the diode has a short circuit. With "1"
displayed, the diode has a forward voltage higher than 2 V
is used for checking conti-
at the rotary switch. When placing
