VOLTCRAFT VC-530, Инструкция по эксплуатации

Страница: 40 / 104

Proceed as follows to measure frequencies or the duty cycle:
- Turn the device on at the rotary switch and select the „V/Hz“ measuring range.
- With the MODE key (7) select the alternating voltage measurement range (AC)
- Select with the Hz% key (6) whether you would like to measure frequencies „Hz“
or the duty cycle „%“ - the selected unit appears on the display.
- Connect the measuring lines with the measuring device as specified under volt-
age measurement
- Now connect the two measuring prods to the object to be measured (generator,
switching etc.).
- - The measuring value is indicated on the display
- After measuring, remove the measuring leads from the measuring object and
turn the measuring device off. Turn the rotary switch to „OFF“.
c) Resistance measurement

Make sure that all the circuit parts, switches and components
and other objects of measurement are disconnected from the
voltage at all times.
Proceed as follows to measure resistances:
- Turn the measuring device on at the rotary switch and select measuring range
„Ω “.
- Plug the red measuring lead into the Ω measuring socket (11), the black mea-
suring line into the COM measuring socket (10).
- Check the measuring leads for continuity by connecting both measuring prods to
one another. After that the resistance value must be approximately 0.5 Ohm
(inherent resistance of the measuring leads).
- Press the REL key (8) to not let the inherent resistance of the measuring leads
flow into the following resistance measuring. The display shows 0 Ohm
- Now connect the measuring prods to the object to be measured. As long as the
object to be measured is not high-resistive or interrupted, the measured value
will be indicated on the display. Wait until the display has stabilised. With resis-
tances of >1 MOhm, this may take a few seconds.
