i) Frequency Measuring
• Turn the DMM on and select measuring function
“Hz”.
• Plug the red measuring lead into the V measuring
socket (9) and the black measuring lead into the
COM measuring socket (8).
• Now connect the two measuring prods to the ob-
ject to be measured (generator, signal, etc.).
• The currently measured value is indicated on the
display
• After measuring, remove the measuring lines
from the measured object and turn the DMM off.
j) Pulse Width Measurement
Pulse width measurement enables measuring of the positive hal-wave of a measuring signal.
The ratio of the positive half-wave to the total signal is displayed. For symmetrical signals (e.g.
sinus), the positive and negative half-waves are the same length. The display shows approx.
50%.
• Turn the DMM on and select measuring function
“Hz”.
• Plug the red measuring lead into the V measuring
socket (9) and the black measuring lead into the
COM measuring socket (8).
• Press “MODE” button to switch measurement
functions. The symbol “%” appears in the display.
Pressing this button again takes you to the first
measuring function etc.
• Now connect the two measuring prods to the ob-
ject to be measured (generator, signal, etc.).
• The currently measured value is indicated on the
display
• After measuring, remove the measuring lines
from the measured object and turn the DMM off.
