Using a Bench-Top Power Supply
If you are using a bench-top power supply or a 9-volt
battery:
1. Set the input coupling switch to
GND.
Important
: You must first set the input coupling
switch to
GND
to initialize the probe every time
you turn on the ProbeScope, even if you want to
measure a circuit’s signal using the same settings
previously used.
2. Insert the supplied power cable’s barrel plug into
the Probe-Scope’s power jack.
3. Connect the supplied power cable’s alligator clips
to the DC power source.
Cautions:
• Make sure the input power source is between
+9V DC and +13V DC.
• Make sure to observe the proper polarity by
connecting the red clip to + and the black clip
to –.
