Thresholds
The Thresholds tab allows you to set threshold values for the auto tests.
Each parameter is described below:
³
Max AC Voltage (V) defines the
maximum AC voltage, ranging
from 1 to 20. Default value is 6.
³
Max DC Voltage (V) defines the
maximum DC voltage ranging from
1 to 20. Default value is 9.
³
Min Resistance (MOhm) defines
the minimum resistance ranging from 0.5 to 100. Default value is 3.6.
³
Max Cap. Balance (%) defines the percentage maximum capacitance
balance ranging from 0 to 20. Default value is 6.
³
Min Long Balance (dB) defines the minimum longitudinal balance
level ranging from 50 to 70. Default value is 59.
To set a threshold value:
1. Press the up/down arrow keys to highlight the desired parameter.
2. Press to select the value.
3. Press the left arrow key to erase the existing value, and then use the
alphanumeric keypad to enter a value. To cancel the entry, press .
4. Press to accept the value.
