Frequency
•
Connect the black plug to the COM input jack and the red plug to the V
ΩmA input jack.
•
Select “Hz“ with the rotary function switch.
•
Connect the meter to the signal source.
•
Press the SELECT key to switch between frequency and duty cycle.
Notes:
•
Only Auto Range mode is possible when making a frequency measurement.
•
If the input voltage is above 10 V (AC, RMS), choose AC voltage measurement and
select frequency or duty cycle.
•
When you are in frequency mode, do not measure any voltages above 250 V AC/DC.
Otherwise, the meter can be damaged.
5.8
Non-contact voltage detection (NCV)
Note:
This measurement can be affected by lots of different external interfering sources which
means that the meter will also react when it receives false signals. This function is only for
orientation and should not be the only way to detect voltage
•
Select
“NCV“ with the rotary function switch. When you come closer to a voltage or signal,
the meter will display the signal strength and emit an audible alarm.
5.9
Diode and continuity test
•
Connect the black plug to the COM input jack and the red plug to the V
ΩmA input jack.
•
Select the
„
“ position with the rotary function switch. Press the SELECT key to
choose diode or continuity.
•
Forward direction measurement: Connect the red test lead to the positive side and the
black test lead to the negative side of the diode. The display will show the dropping
forward voltage.
•
Backward direction measurement: Connect the red test lead to the negative side and the
black test lead to the positive side of the diode.
”OL“ will be displayed.
•
If you do not get the mentioned results, this means that the diode is defective.
•
Press the SELECT key to choose continuity test.
•
Touch two spots in the circuit with the measuring tips. When the resistance is below 50
Ω,
a buzzer can be heard.
•
Note
: Do not measure voltages when the rotary function switch is in
“
” position.
Make sure that no voltage is present in the circuit!
