7. SPECIAL FEATURES
7.1
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 EnerSave disabled), the tester will
beep, indicating the operator that the resistance value measured at 30
second now has been saved internally.
1 Minute after starting a test (with EnerSave disabled), the tester will beep
again, indicating the user that the DAR result is now computed, and
change the display formate to now display the DAR result.
7.2
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 Minute after starting a test (with EnerSave 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.
7.3
Digital Display.
The digital Liquid Crystal Display is large size.
It measures (W) 98mm X (H)24mm and has a 2 Lines of 16 Characters.
7.4
Automatic Battery Test.
When the tester starts, it test it’s 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.
