3.10 Red/Green Polarity LED
The Red/Green Polarity LED lights up when the probe tip voltage matches the
battery voltage within ± 0.8 volts. It is added information that could be valuable to the
Technician.
If the circuit you are testing is not within a 0.8 volt (plus or minus) of supply voltage,
you will see the voltage reading on the LCD but you will not hear a tone or see a red
or green LED. This tells you either you have a voltage drop in excess of 0.8 volt from
battery voltage or you are probing a circuit that has an increase of a 0.8 volt or more
over battery voltage.
To determine battery voltage, simply remove the tip from the circuit and press the
power switch forward. Battery voltage will then be displayed on the LCD. The difference
between the battery voltage and what is read on the circuit is either voltage drop or
voltage increase. This allows you to determine a voltage drop without running back to
check the battery. It ’ s just another one of time saving feature the tool has.
