ADS -942A

Use external trimpots to remove system errors or to reduce
small initial errors to zero. Use a 100
trimpot in series
with the analog input for gain adjustment; use a fixed 50
resistor in its place for operation without adjustment.
Use a 20k
trimpot with the wiper tied to OFFSET ADJUST
(pin 5) for zero/offset adjustment. Connect pin 5 to ANA-
LOG GROUND (pin 6) for operation without zero/offset
adjustment.
