OPERATION
Function/self test
• Test the voltage tester on a known source before use.
• Connect test probes to the voltage source.
• An alert tone should be audible and the LED Rx/Ω (9) should illuminate.
• The voltage indicator LED’s operate whether batteries are fitted or not but the work
light function and audible sounder requires batteries to function.
Voltage test
• Connect the test probes across the source under test.
• The voltage is indicated by the LED’s (4) and an audible tone is output.
• If the polarity is positive the “+” LED is lit and if the voltage is AC both “+” and “-”
are illuminated.
• The measured result is displayed by the LED voltage indicators which are
12V, 24V, 50V, 120V, 230V, 400V, and 690V. Voltages lower than 12V are not
displayed.
