UEi Test Instruments IRT807 Mode D'emploi page 10

The IRT807 is equipped with an AC "low-pass" filter. When measuring AC voltage press the Select Button to activate the "low
pass" filter function. The meter continues to measure in the selected AC mode, but the signal passes through the filter that blocks any
unwanted frequencies above 1kHz. The "low-pass" filter can improve measurement performance on composite sine waves that are
typically generated by frequency motor drives and inverters.
WARNING
• Use CATIII rated Test leads or higher.
• Do not attempt to measure more than 1000V AC.
• Keep hands below finger guards when measuring high voltage levels.
