Operation
Voltage test
• Connect both test probes with power source.
• As from a voltage of >12V the voltage tester switches on automatically.
• The voltage is displayed via LEDs
• For AC voltages the “+” and “-“ LEDs are illuminated.
• For negative voltages “-“ LED are illuminated
• The instruments are equipped with a LED row comprising ± 12, 24, 36, 50, 120,
230, 400V AC/DC. For DC voltage the polarity of the voltage displayed refers to the
instrument test probe “+”.
• The instrument cannot effectuate an automatic switch on for voltages within the
range of approximately 0V to ±12 V.
Maintenance
When using voltage testers in compliance with the instruction manual, no particular
maintenance is required. If functional errors occur during normal operation, you should
send the instrument to Elma Instruments.
Cleaning
Prior to cleaning, remove voltage test from all measurement circuits. If the instrument are
dirty after daily use, it is advisable to clean them by using a damp cloth and a mild
household detergent. Never use acid detergents or dissolvent for cleaning.
