Data value format
16-bit, two’s complement
Accuracy
Voltage mode
@ 25° C [77° F]: ±0.5% full scale
Drift: ±0.02% full scale/°C
Current mode
(3)
@ 25° C [77° F]: ±0.6% full scale
Drift: ±0.03% full scale/°C
Tachometer mode
@ 25° C [77° F]: ±2% gain error
drift: ±0.1%/°C additional gain error, due
to temperature
Example for a module at 100 Hz and 55 °C:
Accuracy = 100 Hz x
(0.02 + (0.001 x (55-25))) =
100 Hz x (0.02 + 0.03) = ±5 Hz error
