Sbecial Function Describtion
~~
Selects the Automatic Cal Factor mode. This
en-
ables the Measuring Receiver to automatically se-
lect
cal factors based on those entered using Special
Function 37.3.
Selects the Manual Cal Factor Mode. This enables
the user to override the automatic selection of cal
factors.
Procedure :
To enter a manual cal factor, select:
37.1 SPCL, cal factor value,
O h
CAL FACTOR (Blue
Key, MHz)
Displays the status
of the cal factor mode
(0 =Automatic,
1 =
Manual).
Prepares
to enter a reference cal factor or a fre-
quencyhl-factor pair into the appropriate table in
memory.
Procedures:
To enter the reference cal factor, select: 37.3 SPCL,
cat factor value,
O h
CAL FACTOR (Blue Key, MHz).
To enter each frequencykal-factor pair, select:
37.3 SPCL, frequency value (in MHz), MHz key, cal
factor value,
O / O
CAL FACTOR (Blue Key, MHz). (It's
unnecessary to wait until the values are displayed be-
fore continuing with subsequent entries.)
(See examDles in this section.)
Displays the number of entries in the table.
Prepares to recall the reference cal factor from the
table.
Procedure:
To display the reference cat factor, select:
37.5 SPCL,
O/O
CAL FACTOR (Blue Key, MHz).
Prepares to recall the next frequencykal-factor pair
from the table.
Procedure
:
To display the frequency, select:
37.6 SPCL, DISPLAY FREQ (Blue Key, kHz).
To display the cal factor, select:
O/O
CAL FACTOR (Blue Key, MHz).
37.6 SPCL sequentially accesses frequencykal-factor
pairs.
(See example in this section.)
Clears the table of cal factors from memory.
To

The table in memory is accessed sequentially (the low-
est frequency accessed first). To access the lowest fre-
quency in the table, select 37.5 SPCL before selecting
37.6 SPCL.

This special function configures the Measuring Re-
ceiver to use manual cal factors with the cal factor re-
called last from the table as the manual entry. To re-
