DAR = Eielectric Absorption Ration. 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 EnerSave (tm) disabled), the tester will beep, indicating the operator that the resistance value measured at 30 seconds now has been saved internally. 1 Minute after starting a test (with EnerSave (tm) disabled), the tester will beep again, indicating the user that the DAR result is now computed, and change the dispaly format to now display the DAR result.
PI = Polarization index. The Polarizatin 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 EnerSave (tm) disabled), the tester will beep again, indicating the user that the PI resuit is now computed, and change the display format to now display the PI result. The tester will Auto-Stop at 10 minutes.
Digital Dispaly : The digital Liquid Crystal Dispaly is large. It measures 98mm(W) x 24mm(H) and has 2 Lines of 16 Characters. Language can be changed on demand, as an option. Dutch /French / German etc... (factory fitted at order)
Automatic Battery Test. When the tester starts, it test its batteries by drawing a heavy current from the batteries. During that heavy current, it measure the battery voltage and displays it for a few seconds on the display. Durig 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 is 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.
