G.2 Output specifications
Specifications Input/Output Details
BCD data Output Five-digit parallel output
POL. (polarity) Output
Output is turned on for the negative polarity while
turned off for the positive polarity.
P.C. (print command) Output
Turned on for a given period after completion of BCD
output conversion
ERROR Output Turned on whenever any error occurs
OVER Output
Turned on in synchronization with the OL display
(overload)
Decimal point display

Output
Turned on in synchronization with the decimal point
display position setting
STABLE Output Turned on upon detection of stable condition
GROSS Output Turned on upon output of total value data
HOLD Input Holds the BCD output.
BCD-ENABLE Input Forces the BCD output into high impedance condition.
G.3 Setting
Output operation mode, output target, output logic, PC width, and output frequency for the BCD are
set with the following functions.
Item Function Setting
BCD output
operation mode
F-30 0 (Stream mode), 1 (Print signal synchronization)
BCD output target F-31 0 (Display interlock), 1 (Track), 2 (Peak)
BCD output logic F-32 0 (Negative logic) or 1 (Positive logic) is set using four digits.
Digit Setting details
First digit
Data output logic (load data and decimal point
display position)
Second digit
Polarity output logic
Third digit
Plug output logic (error, over, stable, total value)
Fourth digit
P.C. (print command) output logic
BCD PC width
F-33
0 (125 ms), 1 (25 ms), 2 (10 ms), 3 (5 ms), 4 (1.25 ms),
5 (0.5 ms), 6 (0.25 ms) , 7 (0.125 ms)
BCD output
frequency
F-34
0 (4 times/s), 1 (20 times/s), 2 (50 times/s), 3 (100 times/s),
4 (400 times/s), 5 (1 000 times/s), 6 (2 000 times/s) ,
7 (4 000 times/s)
CAUTION
During the rising stage of the print command, the BCD data is being converted, and
the values are therefore unstable. For this reason, read the BCD data during the
falling stage of the print command.
