VOLT: It sets insulation resistance test needed voltage.
LOW: It sets insulation resistance low limit value.
TIME: It sets test needed time, input 0 means continuous test.
HIGH: It sets insulation resistance high limit value, input 0 means OFF.
RAMP: Step-up setting voltage needed time, input 0 means OFF.
FALL: The needed time is from setting voltage value to zero, 0 means OFF.
RNG: It sets the current test range of insulation resistance, AUTO means
automatic switch range. The relation of current range and
resistance measurement range is as below table shown.

Note
Select IR suitable current range please follows test voltage and
DUT insulation resistance for counting the quantity of current then
follows it to select suitable current range.
SCAN: It sets scan test selection point.
