Auto-discharge
This function releases the capacitance stored in a circuit after testing.
The LCD will flash "AUTO DISCHARGE" when the meter is in discharge
condition and the live voltage monitor will display "O V". This function
will be released by removing test leads 2 sec or more before discharge is
complete. Set the range switch to "OFF" position, and remove test leads
from the instrument.
Insulation Resistance Measurement Principle
Insulation tests should only be performed on de-energized circuits.
Continuous Insulation Resistance Measurement
Press and turn the "PRESS TO TEST" button clockwise to perform a con-
tinuous insulation resistance measurement. After testing, turn the button
counterclockwise to the initial position. A beep will sound and the reading
will hold on the LCD for 10 seconds.
Timer Insulation Resistance Measurement
This is a function to automatically conduct a test at a set time (from 1 min
to 15 min).
1. Press the Time-up and Time-down buttons to set the time from 1
min to 15 min.
2. To activate the timed insulation resistance measurement, press and
turn the "PRESS TO TEST" button clockwise till it locks.
3. After testing, turn the button counterclockwise to the initial posi-
tion. A beep will sound and the reading will hold in the LCD for 10
seconds.
Polarization Index and Dielectric Absorption Ratios
Polarization Index (PI) is the ratio of a 10-minute to 1-minute insula-
tion resistance. Polarization index = resistance value measured after 10
min (Time2)/resistance value measured after 1 min (Time1). Dielectric
