Frequency Measurement (Hz); Low Resistance Indication (L Rx); Diode Test ( ); Data Hold (Hold) - Beha-Amprobe 2100-Delta Manuel De L'utilisateur

Frequency Measurement (Hz)

• Switch into frequency measurement by pressing On/
Off-Function button repeatedly until Hz symbol is shown
on LCD.
• Connect both test probes to the AC voltage under test.
Frequency from 1 Hz to 800 Hz 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 >120 V. ELV diode will indicate voltages >50 V AC
and >120 V DC.

Low Resistance Indication (L Rx)


The test circuit/object shall be de-energized
before measurement.
• Check for the absence of voltage by conducting a two
pole voltage test on the test object.
• Press ON/OFF/Function button repeatedly until LCD
shows "L Rx" symbol.
• Connect both test probes to the test object. At
resistances lower than 20 Ohm LED Rx is ON, the LCD is
showing "Con" and the buzzer is active.
• Tester automatically switches OFF after approx. 30
seconds if no continuity is detected. If continuity is
detected the tester switch automatically ON again.
• Tester switches to voltage measurement if voltage more
than 6V is detected.
This feature is very helpful to check wiring in contactor
and relay application without influence of the coils.
Diode Test (

The test circuit/object shall be de-energized
before measurement.
• Check for the absence of voltage by conducting a two
pole voltage test on the test object.
• Switch into diode testing mode by pressing ON/OFF/
Function button repeatedly until diode symbol is shown
on LCD. Connect both test probes to the diode under
test.
The continuity LED lights and the buzzer sounds when L2+ is
connected to the anode and L1- is connected to the cathode.
Indication will be OFF if L2+ tip is connected on Cathode of
diode and L1- tip on Anode.
Tester will switch to voltage measurement if voltage >6 V or
single pole is detected during diode testing.

Data Hold (HOLD)

After pressing the "Flashlight/HOLD" button ≥ 2 seconds ,
the data hold function is activated and replies with a short
sound. The LCD screen shows "the last measured value" and
symbol "HOLD". The hold function can be deleted manually
by pressing the "Flashlight/HOLD" button again for > 2 sec.
The data hold function is now deactivated and replies with a
short sound.

Under data hold mode, the LCD screen will only show the
last saved measured value. No auto refresh of LCD screen
reading under Data Hold mode whether the voltage tester is
connected to energized or non-energized circuit. The LED
voltage indicators will always show the actual voltage level of
the circuit under measurement.

Measurement Area Illumination / Flashlight / LCD Backlight

The voltage tester features a measurement area illumination
and a LCD backlight. This facilitates work under poor lighting
conditions (e.g. distribution/control cabinets). To activate the
Flashlight and LCD backlight press the Flashlight/Hold button
for measurement area illumination. After approx. 30 sec. it
will turn itself off.
