5. Test Tool Know-how
1) Is the Power Scan Probe Tester computer and air bag safe?
The tool LED and LCD pull no more than 1 milliamp of current, therefore when using it
as a test light or multimeter it is computer and airbag safe. However, pressing the power
switch is a different story. When you press the switch forward, you are
conducting full battery current to the tip of the probe. There is a nice safety feature
built into the tool. Simply connect the extra ground lead to the tool and press the
power switch forward until it trips the circuit breaker. This will prevent power from
going to the tip but still allow you to use the tool as a multimeter. When you are away
from computer components, simple press the reset button and you are ready to power
up again.
2) Why do I have no power at the tip when I am pressing the power switch forward
but the red LED is on?
The power switch goes through a lot. It is one of the few things that go wrong with the
tool. The switch is a consumable that needs to be replaced on occasion. We have
made it real simple to not only change it but also buy a new switch. The switch can
be snapped out and replaced in seconds.
You can buy switches from your authorized tool supplier.
The tool with the Rocker Switch slots makes it easy to replace a worn switch in the field
