Using an AC Adapter

If you are using an optional AC adapter:

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 proper-sized barrel plug into the

adapter’s wire jack so it reads TIP +.

3. Insert the barrel plug into the ProbeScope’s

power jack.

4. Connect the AC adapter’s power module to a

standard AC outlet.

Caution

: Use only an AC adapter that supplies 9–

13 volts DC, delivers at least 100 milliamps, and

has a barrel plug that correctly fits the Probe-

Scope’s power jack with its center tip set to posi-

tive. The recommended AC adapter meets these

specifications. Using an adapter that does not

meet these specifications could damage the

ProbeScope or the adapter.
