BCD 1% units
1
BCD 0.1% units
2
BCD 0.01% units
3
BCD 1 Hz units
4
BCD 0.1 Hz units
5
BCD 0.01 Hz units
6
Special BCD settings (5-digit input from 0.00 to 399.99 Hz)
(See notes 1 and 2.)
7
Binary input (binary values displayed in decimal)
Note
1. The second digit below the decimal point is set by bits
8x10
0
, 4x10
0
, and 2x10
0
, so the settings are made in
units of 0.02 Hz. (If these three bits are “111,” “110,”
and “101,” they will be recognized as “9.”)
2. Only positive data can be set in order to use the Sign
(CODE) bit as a data bit.
