DAR (Dielectric Absorption Ratio)
The dielectric Absorption Ratio is the ratio of the Insulation Resistance measured at 1 min divided per the Insulation Resistance measured at 30 seconds. 30 Seconds after starting a test (with Ener-Save disabled), the tester will beep, indicating the operator that the resistance value measured at 30 seconds now hasbeen saved internally. 1 minute after starting a test (with Ener-Save disabled), the tester will beep again, indicating the user that the DAR result is now computed and change the display format to now display the DAR result.
PI (Polarization Index)
The Polarization Index or PI is the ratio of the Insulation Resistance measured at 10 Minutes divided per the Insulation Resistance measured at 1 minute. 10 minutes after starting a test (with Ener-Save disabled), the tester will beep again, indicating the user that the PI result is now computed and change the display format to now display the PI result. The tester will Auto-Stop at 10 minutes.
Digital Display
The digital Liquid Crystal Display is large. It measures 98 mm. (W) x 24 mm. (D) and has a 2 Lines of 16 characters.
Automatic Battery Test
When the tester starts, it test its batteries by drawing a heavy current from the batteries. During that heavy current, it measures the battery voltage and displays it for a few seconds on the display. During normal use, the tester monitors the battery voltage, but without drawing a battery test current. It just measures the battery while in normal use.
Automatic Discharge of Capacitive and Inductive Circuits
This tester will discharge automatically all circuits charged by the tester, after a test is done, again, this will only be activated if the test leads make contact at any time before, during and after the test. It’s your responsibility to ensure proper contact of the leads at all Times. Once a test is finished, the testers will automatically discharge capacitive or inductive circuit of their charge. The discharge can be observed on the display, in the form of a bar-graph. Again, do not disconnect the leads while discharging. Wait until completion of the discharge before removing any lead. During discharge, the Buzzer will beep and the bar-graph will show some voltage. With some high charges, this may take some time. Be patient and let the instrument discharge completely before proceeding to removing the leads.
