Stand: 29.8.19 GB
•
Measurement principle: The instrument detects the phase rising order regarding the user as
earth.
Function of this test may not be fully achieved if the insulation condition/ grounding
conditions of user or of the equipment under test is not good enough.
7.5.
Continuity test
Make sure the object under test isn’t live.
•
Connect both test probes to the object under test.
•
Continuity is shown by light up of the LED and a sound if resistance is below 500kOhm
•
If a lower threshold for continuity is preferred, low continuity mode can be selected
o
Press Torchlight/Function button repeated until LCD shows
LRx
symbol is shown
on LCD
o
Continuity is shown by light up of LED and sound if resistance is below 20Ohm
Continuity test performed automatically in all modes except in Low Voltage and
Resistance mode.
Tester switch to voltage measurement if voltage is detected during continuity testing
>6V
7.6.
Diode test
Make sure the object under test isn’t live.
•
Switch into diode testing mode by short pressing
On/off
/Function button repeated until
symbol is shown on LCD. Connect both test probes to the diode under test.
Continuity LED lights up, buzzer sounds continuously and
Con
symbol on LCD is on
if L1 tip is connected on Anode of diode and L2 tip on Cathode.
Continuity indication will be off if L1 tip is connected on Cathode of diode and L2 tip
on Anode.
Tester switch to voltage measurement if voltage >6V or Single pole is detected
during diode testing
7.7. Resistance test
Make sure the object under test isn’t live.
•
Switch into resistance measurement by pressing
On/off
/Function button repeate k
Ω
symbol is shown on LCD. Connect both test probes to the object under test. Resistance up
to 100k
Ω
can be shown on LCD. For resistance less than ~20
Ω
buzzer sounds
continuously to indicate low continuity.
Tester switch to voltage measurement if voltage >15V or Single Pole is detected.
7.8. Frequency test
•
Switch into frequency measurement by short pressing
On/off
/Function button repeated
until
Hz
symbol is shown on LCD. Connect both test probes to the AC voltage under test.
Frequency from 1Hz to 800Hz can be shown on LCD.
Frequency measurement is possible for voltages >10V AC.
The level of voltage will be shown only on bar graph for voltages >120V. ELV diode will
indicate voltages >50VAC and >120VDC.
7.9. Cable break detection by NCV
•
Switch into frequency measurement by pressing
On/off
/Function button repeated. LCD will
show
NCV
symbol.
•
The NCV function is used to find e.g. after a cable breaks
