(7) COMPARATOR ENABLE Switch: This
switch enables the Option 004 to compare
measured data with HIGH and LOW limits
under a fixed range condition (LCR or D/Q
RANGE switch set to MANUAL). If LCR

AUTO, depressing COMPARATOR EN-
ABLE switch changes LCR or D/Q RANGE
switch setting to MANUAL.
If AUTO key of LCR or D/Q RANGE
switch is depressed while COMPARATOR
ENABLE switch is ON, one measurement
cycle is done in AUTO ranging and the
range is fixed to that selected in this meas-
urement cycle.
