The Amps Probe Kit contains a Low Amps
Probe, a High Amps probe, an interface
module, a BNC to Banana adapter, and a
storage pouch.
To Measure Low Amps with a DMM
1. Connect the Low Amps Probe to the
in ter face module.
2. Connect the interface module to the
multimeter’s banana jacks.
3. Select the millivolts range.
4. Close the Jaws on the Low Amps Probe
and zero the reading on the DMM by
adjusting the zero knob on the interface
module.
5. Clamp the Low Amps Probe around
the circuit you want to test. 1 Millivolt
equals 10 Milliamps. A reading on the
Mul ti m e ter of 34.4 Millivolts means you
are mea sur ing 344 Milliamps.
To Measure High Amps with a DMM
1. Connect the High Amps Probe to the
in ter face module.
2. Connect the interface module to the
multimeter’s banana jacks
3. Select the millivolts range.
4. Zero the reading on the DMM by
adjusting the zero knob on the interface
module.
5. Clamp the High Amps Probe around the
circuit you want to test. 1 Millivolt equals
1 Amp. A reading on the Mul ti m e ter of
123 Millivolts means you are mea sur ing
123 amps.

To View Waveforms on a Lab Scope
1. Connect the Low or High Amps Probe
to the in ter face module.
2. Connect the interface module to one
of the LabScope’s Channels. Use the
BNC or Banana Adapter as needed.
3. Select a volts per division and a time
base that will allow you to see the
waveform of the circuit under test.
4. Make sure the jaws are closed on the
Amp Probe and zero the trace on the
LabScope by adjusting the zero knob
on the interface module.
5. Clamp the Amps Probe around the
circuit you want to test and view the
waveform.
Other Instructions

options. The fi rst time you press the power
button the LED will fl ash indicating the unit
will stay on until the battery is dead.
The second time you press the power
button, the LED will stay on indicating
