Page 2: Safety Warnings
SAFETY WARNINGS Safety Warning must be observed during use. The circuit under test must be switched off, de-energised, isolated and checked to be safe before insulation test connections are made. Make sure the circuit is not re-energised whilst the instrument is connected. Circuit connections must not be touched during an insulation test. -

If The instrument will only turn on if this button is pressed, held and then the test voltage is changed during a test, the new test voltage will be released when the display responds. - Page 8 details available when scrolling the secondary display will depend upon the test mode selected, whether timers T1 and T2 have been set, and the duration of the test. The digital display toggles between insulation resistance and current. In the ‘IR’, ‘PI’, and ‘DD’ modes the secondary display initially shows the PI (polarity index), DAR (dielectric absorption ratio), and, on completion Press Ω/I of the test, the TC (time constant) and capacitance measurements.
