5.3 Non-contact voltage measurements
Risk of electrocution. Before use you should always test the voltage detector on a known
live circuit to verify proper operation of the meter
1. Hold the probe against the hot conductor or against the hot side of the electrical outlet..
2. The two detector LEDs light up red if an AC voltage is detected.
Notes
The conductors in an electrical cord are often twisted. Rub the probe tip along a length of cord to be sure
•
the tip passes in close proximity to the live conductor.
The detector is a sensitive device. Static electricity or a different energy source may randomly trigger the
•
sensor at random. This is simply part of the normal operation of this device, it is not a malfunction.
Frequency measurements
1. Put the function switch in the Hz-position.
2. Close the jaws completely around the conductor to be measured.
3. Read the frequency value on the LCD.
Flashlight
Hold the top button to turn on the flashlight.
Data hold
1. Press the "Hold backlight" button to freeze the current reading on the LCD.
The word "HOLD" will appear on the LCD when the data hold mode is activated.
2. Press the "Hold backlight" button again to return to the normal display mode.
The word "HOLD" is erased from the display.
Backlight
