A622 Instructions 1
Getting Started
The A622 current probe (Figure 1) enables a general purpose
oscilloscope to display AC and DC current signals up to 100 amps
Peak (70 A RMS). The A622 current probe can also make AC and
DC measurements with a multimeter by using the BNC-to-banana
plug adapter that is available as a recommended accessory. See
page 17 for ordering information.

Table 1 highlights the controls and indicators on the A622 current
probe.
Table 1: A622 controls and indicators
Control/Indicator Description
Current flow symbol. The arrow show the probe’s polarity
convention for measuring current flowing from positive to
negative.
ZERO Zero adjustment. Rotate to adjust the probe output to zero when
there is no current present. It may also be used to offset a DC
signal component. Zeroing is not needed for AC measurements
unless your instrument cannot isolate a DC component (if
present).
OFF/Range switch. Slide the switch from OFF to either the
10 mV/A or 100 mV/A range. When either range is selected, the
probe is turned on, and the green battery indicator lights. If the
indicator does not light, see Battery Notes and Battery Installation
on page 7.
Battery indicator. The green battery indicator lights when the
probe is turned on. For more information, see Battery Notes and
Battery Installation on page 7.
Overload indicator. The red overload indicator lights if the
measured signal is greater that the selected range capacity.
Switch the probe to 10 mV/A if possible, or remove the probe from
the circuit.
A622 Instructions 3
Operating Basics
Before using the probe, the batteries must be installed. See the
battery installation instructions on page 7.
WARNING. Do not clamp the probe onto circuits with voltages greater
than 600 VAC. Personal injury or damage to the probe may result.
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,
the vertical deflection to 0.1 V/div.
2. Move the OFF/Range switchtothe10 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.
4. Connect the probe to the circuit by opening the jaws and
clamping around the conductor. See Figure 2.
NOTE. Clamping around both the “hot” and neutral wires may give
you a zero reading.
(Remember to unclamp the probe from the conductor before
disconnecting it from your meter or instrument.)

5. Adjust the probe and channel as necessary to get a clear view of
the signal. Set the channel to DC volts to see both the AC and DC
currents; set the channel to AC to see the AC current only.
The current drawn by some devices looks much different than that of
others. While the RMS current may be low, the momentary peaks
may be quite high. Figure 3 shows the difference between the line
current drawn by a resistive load and a motor controller.
