WHAT CAN YOU VIEW?
1) "A sub B" - If you have selected the "A sub B" mode, pressing "view" shows:
A) The net result of subtracting input B from input A. Pulses on input B will subtract (count down). Pulses on input A
will add (count up) if "reset to 0" is selected, if "set to preset" is selected, input A will subtract (count down).
B) The rate of input A.
2) "A add B" - If you have selected "A add B" mode, pressing "view" shows:
A) The net result of adding "A" and "B" inputs. Pulses on input B will add (count up). Pulses on input A will add
(count up) if "reset to 0" is selected, if "set to preset" is selected input A will subtract (count down).
B) The rate of input A.
3) "A sep B" - If you have selected " A sep B" mode, pressing "view" shows:
A) The total counts of input A. If "reset to 0" is selected A counts up, if "set to preset" is selected A will count down.
B) The rate of input A.
C)* The total counts of input B. B will always count up.
NOTE: In "A sep B" mode, B can be used in 3 ways:
1) As a separate totalizing counter
2)** As a Batch Total Counter for input A
3)** As a Grand Total Counter for input A
NOTE:
* All decimal points are inverted when "B total" is being displayed.
** See below on how to modify for Batch Count and "B" as a Grand Total Counter.

If the unit has the millivolt input bd.# 20229, A & B inputs can be
separately solder jumper programmed to accept either a low milli-
volt or 4-30 V input. Each unit shipped is programmed according
to part number. If solder jumpers are made, the part number
should be modified to reflect the changes made
