E) Measuring Frequency And Pulse Duration - VOLTCRAFT VC-532 AC Bedienungsanleitung

Follow the steps below to measure DC (V
• Turn the multimeter on and select "LoZ V
pear on the display.
• Press the "MODE" button to switch to DC mode. "DC" will appear on the dis-
play.
• Plug the red lead into the V terminal (K) and the black lead into the COM
terminal (I).
• Connect both of the test prods to the measured object (battery, circuit etc.)
in parallel. Connect the red measuring probe to the positive terminal and the
black measuring probe to the negative terminal.
• The measured value is displayed together with the polarity.
If "-" appears in front of a direct voltage measurement, this indicates
that the measured voltage is negative (or that the measuring probes
have been connected in reverse).
The "LoZ" voltage range has an input resistance of <200 kOhm.
• After measuring, remove the test leads from the measured object and turn the
multimeter off.

e) Measuring frequency and pulse duration

The multimeter can be used to measure the frequency of a signal voltage (sup-
ports frequencies from 5 Hz to 10 kHz). Observe the input specifications in the
technical data.
Proceed as follows to take a frequency measurement:
• Switch on the DMM and select "Hz" mode. Frequency measurements can be
made with normal or low impedances (LoZ Hz). Only select the "LoZ Hz" func-
tion in special circumstances. "V
• Press the "Hz%" button once. "Hz" will appear on the display.
• Plug the red lead into the Hz terminal (K) and the black lead into the COM
terminal (I).
• Connect the two measuring probes to the object that you want to measure (e.g.
signal generator or circuit).
• The frequency will be displayed together with the corresponding unit..
• After measuring, remove the test leads from the measured object and turn the
multimeter off.
In DC mode, your cannot switch to frequency measurement or pulse duration mode.
