1. Set output OUT jumper to V or MA as desired.
2. Set INPUT jumpers for type and range of input signal
present. See “Input Jumpers” table above.
3. If using the reference output for sensor excitation, set the
two REF jumpers for the proper output type and value.
Choices are 1.2V, 5V, 10V, 1.2 mA, 5 mA, 10 mA. If not using
the reference output, jumper as a voltage output.
4. Set action ACT jumper to direct D or reverse R as desired.
5. Set span jumper SPN to LO. Turn SPAN pot clockwise 25
turns.
6. Remove both Z1 jumpers. Trim ZERO 1 pot for minimum
desired output value. Presence/absence of input signal has
no effect on this adjustment.
7. Reinstall both Z1 jumpers. Set Z2 jumper to LO position.
8. Apply an input signal value that is to produce minimum
output. Trim ZERO 2 pot for minimum output value (same
value set in step 6). If desired value cannot be achieved,
remove Z2 jumper and trim ZERO 2 pot again. If desired
value is still not achieved, place Z2 jumper in HI position and
trim ZERO 2 pot again.
9. Apply input signal value that is to produce maximum output.
Trim SPAN pot for maximum output value. If SPAN pot does
not go high enough, move the SPN jumper from LO position
to HI position.
10. Repeat steps 8 and 9 until both minimum and maximum
output values are correct. Typically, just one more pass is
sufficient.
11. Apply a midpoint input signal. Verify that output goes to
center of output range.
