Page 7: 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. - Page 8 Getting Started 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.

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. - Page 10 Jaws From source Figure 2: Connecting the A622 current probe 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.
