VOLTAGE : It sets the voltage required for insulation resistance test.
LOW LIMIT : It sets the low limit of insulation resistance.
HIGH LIMIT : It sets the high limit of insulation resistance. The range is larger than the
low limit of insulation resistance or OFF.
TEST TIME : It sets the time test required, 0 means continue test.
RAMP TIME : It sets the time required for ramping to the set voltage, 0 means OFF.
FALL TIME : It sets the time required for falling to low voltage from set, 0 means OFF.
RANGE : It sets the current test range for insulation resistance, AUTO means
switching the range automatically. The table below lists the relationship
between current range and resistance measurement range.
