VOLT : Set insulation resistance test needed voltage.
LOW : Set insulation resistance low limit value.
TIME : Set test needed time, input 0 means continuous test.
HIGH : Set 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 : Set 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.
