For IR test, a reference value of tester can be 
automatically created via the GND OFFSET 
function. See page 68 for details. 
For GB and CONT tests, a reference value of test 
lead can be automatically created via the ZERO 
CHECK function. See page 71 for details. 
Setting an Initial Voltage 
 
In essence, the test voltage for both ACW and 
DCW will gradually and linearly rise up, from 
zero, to the target set voltage in accord with the 
set RAMP TIME ahead of the TEST TIME. 
Nevertheless, under certain circumstances, user 
may have preferences on the percentage of 
starting test voltage. Therefore, the INIT 
VOLTAGE provides another alternative for 
different applications on user side.
