Input Accuracy and Alarm Trip Repeatability:
Refer to Table
Overall Accuracy: The overall accuracy
of the unit is the combined input and output
accuracies. It includes the combined e󰀨ects of
linearity, hysteresis, repeatability and adjustment
resolution. It does not include ambient
temperature e󰀨ect. For T/C input, add the RJC
error.

the output to change 10% to 90% of its scale for
an input step change of 0 to 100%
Output Step Response Time: 100msec
maximum
Output Ripple (up to 120Hz): 50mV peak-to-
peak maximum on voltage output; 10mV peak-to-
peak measured across a 250 ohm load resistor
for current output (frequencies up to 120Hz)

operating properly; Red LED indicates unit has
fault or is latched.
Display Accuracy:
±1 digit; when scaling the display (or in custom
mode), high input-to-display span ratios
decrease display accuracy
