3-50. The 4262A Option 004 (shown in Figure
3-43) provides:
(a) HIGH and LOW limits setting for com¬
parison of LCR and D/Q measured data.
(b) LED visual decision output lamps display
of results of HIGH and LOW limit com¬
parisons.
(c) TTL outputs and relay outputs for HIGH,
IN, and LOW decision outputs.

(1) LCR LIMIT Switch: Two four-digit
switches provide HIGH and LOW limit
values with which measured LCR value is
compared. Setting range is from 0000 to
1999.
(2) LCR Decision Output Lamp: Results of
comparison are indicated by LED lamps
as follows;
HIGH: (measured value £ High limit)
IN: (Low limit £ measured value
< High limit)
LOW: (measured value < Low limit)

(4) D/Q LIMIT CHECK Switch: While this
switch is depressed, HIGH and LOW limit
values set by D/Q LIMIT switches (6) are
displayed in LCR and D/Q displays. During
this period, three D/Q lamps of decision
outputs are lit.
(5) D/Q Decision Output Lamp: Results of
comparison is indicated by LED lamps
as follows:
(3) LCR LIMIT CHECK Switch: While this
switch is depressed, HIGH and LOW limit
values set by LCR LIMIT switches (1) are
displayed in LCR and D/Q displays. During
this period, three LCR decision output
lamps are lit. Comparator must be en¬
abled display limits.
HIGH .-(measured value ^ High limit)
IN: (Low limit £ measured value
< High limit)
LOW: (measured value < Low limit)
(6) D/Q LIMIT Switch: Two four-digit
switches provide HIGH and LOW limit
values with which measured D/Q value is
compared. Setting range is from 0000 to
1999.
