Measuring function
Frequency „Hz"
Diode test/continuity check
Currency measuring µA/mA/A
HOLD function
The HOLD button (9) allows you to hold the measuring value on the display. The symbol "H" appears on
the display. This facilitates reading, e.g. for documentation purposes. Another press will switch back to
measuring operation again. With the VC170, the HOLD function is not available in the frequency mea-
suring range "Hz".
Optional measuring adapter
An optional measuring adapter is available to ease the
performance of some measurements. This adapter
facilitates the connection of transistors (also SMD
types) and standard K-type thermal sensors with minia-
ture plugs. Attach the adapter to the three measuring
sockets COM (5) + V (8) + mA (7).
A Transistor test header for NPN types
B Plugin header for K-type sensors (observe the
polarity!)
C Transistor test header for PNP types
Function
Switching between functions
Each press switches the measuring function. Pressing 1x
duty cycle, another press frequency measuring, etc.
Switching between functions
Each press switches the measuring function. Pressing 1x
"continuity check", another press diode test, etc.
Function switching AC/DC
Each press switches the measuring function. Pressing 1x
"AC", another press "DC" etc.
