Maintenance:
Use the information in this section to properly maintain the operation of
your PA-659 AC/DC Current Probe.
1. Notes on Battery and Power Converter:
The PA-659 current probe uses a single square 9 V battery. This machine
is a high power product. Please use the specified alkaline battery.
As the battery in the PA-659 current probe is drained, significant gain
errors may 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.
As an alternative, an AC power converter can be used to avoid gain error
due to poor battery durability. Switch to a square 9V battery only when
there is no AC power supply available outdoors.
When using an AC power converter for an extended time, we suggest you
remove the battery from the compartment. This is because heating will
result in battery leakage, and battery electrolyte will rust the circuit board,
thus creating major damage. Furthermore, batteries are high pollution
products and therefore by reducing their usage, we will in turn protect the
environment.
