Measuring Ac And Dc Voltage; Voltage Detection (Ncv) - Beha-Amprobe ACD-14-PRO Manuel De L'utilisateur

Measuring AC and DC Voltage

To measure AC or DC voltage:
1. Turn the rotary function switch to
2. Connect the black test lead to the COM terminal and the red test lead
to the V terminal. Measure the voltage by touching the probes to the
desired test points of the circuit.
3. View the reading on the lower display.
4. When measuring AC voltage, press SELECT button to view the
frequency reading on the lower display. (SELECT button: toggle among
, Hz, "EF-H" and "EF-L" modes).
AC current can be measured at the same time by using the jaws while the
V/COM terminals are measuring voltage. Upper display shows AC current
measurement. Also see Measuring AC Current and Precise Low Current
Measurement sections.
Note: AC V and Hz function are equipped with digital low pass filter, and
are capable of dealing with VFD (Variable Frequency Drive) signals. It also
improves AC V reading stability in noisy electrical environments.

Voltage Detection (NCV)

Non-Contact Voltage Detection:
Warning
W
To avoid electrical shock and injury:
• Do not hold the meter anywhere beyond the tactile barrier.
1. Turn the rotary switch to NCV(EF) and press SELECT button to toggle to
NCV(EF) mode. Two selectable sensitivity modes:
• "EF-H" indicating high sensitivity detection mode ("EF-H" is
displayed) for the application of better detecting circuit with low
electric field signals.
• "EF-L" indicating low sensitivity detection mode ("EF-L" is displayed)
for the application where the electric field is too strong from the
circuit under testing.
