• In Insulation or Earth-bond resistance Test mode, when pressed before the Test Button, the test remains active until you press the lock or test button again to release the lock. J. Range/Test Voltage/Temperature Scale Button: • Press and hold to return to Auto Ranging mode • Press to select desired voltage source in Insulation Resistance mode. • Press to select °F or °C in Temperature mode.

Voltage: with 1kHz “low-pass” filter <1000V 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.

Measuring Polarization Index and Dielectric Absorption Ratios INSULATION TESTER IRT807 Polarization Index (PI) is the ratio of the 10-minute insulation resistance to the 1 minute insulation resistance. Dielectric Absorption Ratio (DAR) is the ratio of the 1-minute insulation resistance to the 30-second insulation resistance. PI/DAR Apo SMOOTH 50V Test Voltage LOCK • Default = • Press x1 = WARNING • Insulation tests should only be performed on TEST de-energized circuits.
Testing the Fuse • Turn the rotary selector dial to ZERO/Ω position. • Press and hold the TEST button. If the display shows “FUSE”, the fuse is bad and should be replaced. Please see Fuse Replacement section of this manual.
