Maintenance
Use the information in this section to properly maintain the operation
of your A622 AC/DC Current Probe.
Cleaning
To clean the probe body, use a soft cloth dampened in a solution of
mild detergent and water. To clean the core, open the jaw and clean the
exposed core surfaces with a cotton swap dampened with isopropyl
alcohol (isopropanol). Lubricate the jaws mating surfaces with a light
oil.
Do not clean with solvents or abrasives. Do not immerse the probe.
Battery Notes
The A622 current probe uses a single 9 V battery. Refer to Table 2:
Electrical Characteristics on page 8.
As the battery in the A622 current probe is drained, significant gain
errors can occur. The green LED will continue to light until a low
battery voltage of 6.5 V is reached.
If probe gain errors are detected, replace the battery with a fresh one.
Battery Installation
1. Remove the probe from the circuit.
2. Open the battery compartment by loosening the captive screw and
sliding the cover off (see Figure 5: A622 battery compartment on
page 8).
3. While observing polarity, attach the battery to the battery
connector.
4. Replace the cover and lightly tighten the screw to hold the cover in
place.
