CALIBRATION PROCEDURE
Unipolar Output Current
1. Connect the converter as shown in Figure 2.
2. Set all inputs low and adjust the ZERO ADJUST
3. Set all inputs high and adjust the GAIN ADJUST
Bipolar Output Current
1. Connect the converter as shown in Figure 3.
2. Set all inputs low and adjust the OFFSET ADJUST and
3. Set all inputs high and adjust the GAIN ADJUST potentiom-
potentiometer for a reading of 0V at the output.
potentiometer for a reading of –F.S. + 1LSB (See Table 1).
LOAD potentiometer for an output reading of +F.S. (See
Table 2).
eter for an output reading of –F.S. + 1LSB (See Table 2).
