4.2.6 Beeper continuity
Measuring range: 600 Ohm
Resolution: 0.1 Ohm
Description:
When the built-in beeper sounds and the accompanying green indicator is on, the measured Open-circuit
voltage resistance must not be over approx. 1 V 30 Ohm. The red indicator will be on when the resistance
is between 40 and 60 Ohm.
Testing conditions:
Open-circuit voltage: approximately 1 V
Overload protection: 600 V AC/DC

Overload protection: protective tube for mA measuring range (FF630 mA / 250 V); protective tube for 20 A measuring
range (FF 20 A / 250 V).
Maximum input voltage: mA position: 600 mA AC/DC (valid value); 20 A position: 20 A AC/DC (valid value)
If the measured current is over 5 A, the duration of the continuous measurement should not exceed 10 seconds.
The current measurement should be taken 1 minute after the completion of a previous measurement.
