How are the various quantities measured? (continued)
Press the F3 key to access this function.
So as not to damage the circuit
tested, note that the multimeter
provides a current of approximately
10mA max. at an open-circuit voltage
of 28 volts max.
For low resistance measurements,
<100 Ohm, this single range provides
good resolution.
Measurement of a resistance up to
1000 , with continuous 4kHz audible
indication.
Power the circuit down before making
any measurement.
The continuity test monitors the
circulation of the current in a complete
resistive circuit. The continuity function
detects open-circuits and intermittent
short-circuits lasting as little as one
millisecond.
If a short-circuit is detected, an audible
beep sounds. If the circuit is open, OL
is displayed.
Detection threshold in continuity mode:
20 (response time <10ms)
“Active” protection by PTC thermistor
Max. open-circuit voltage: 3.5V.
