Operating Basics
Before using the probe, the batteries must be installed; see Battery
Installation on page 7.
WARNING. Personal injury or damage to the probe can result if you
clamp the probe onto circuits with voltages greater than 600 VAC. Do
not clamp the probe onto circuits with higher voltages. Always connect
the probe to the instrument before clamping onto the circuit under test.
1. Connect the probe BNC connector to the oscilloscope input. Start
by setting the oscilloscope channel vertical coupling to DC volts
and the vertical deflection to 0.1 V/div.
2. Move the OFF/Range switch to the 10 mV/A or 100 mV/A
position to power on the probe.
The A622 current probe has a green LED power/battery indicator.
If the LED does not light, replace the battery.
3. Use the ZERO adjustment to zero or offset the probe output.
