This product detects absolute
values so that negative DC
voltages can be applied. The
above values for AC voltages
are those obtained with sine
wave signals of 50/60 Hz.
NOTE
Refer to the manual supplied with the 9321-01 LOGIC PROBE
for details.
9321-01 LOGIC PROBE
Use to determine whether power to a circuit is on or off.
Set the input selector according to the measured voltage.
LOW range: 100 V AC or 24 V DC
HIGH range: 200 V AC
The inputs are bipolar, so polarity may be disregarded.
As the inputs are isolated, each channel can be connected
to points with different potential.
