3.1 Voltage & Polarity Testing
While the tool is in DC Voltage mode, contact the probe tip to a
POSITIVE circuit. The red LED will light and the LCD displays the
voltage with a resolution of 0.1V. If the beep is turned on, a high
pitched tone will sound.
If contact the probe tip to a NEGATIVE circuit, the green LED will
light and the LCD displays the voltage with a resolution of 0.1V. If
the beep is turned on, a low pitched tone will sound.
If contact the probe tip to an OPEN circuit, neither of the LED will
light.(Figure 7)
