CALIBRATION
–
Each Output Separately
Click the
[Output Cal Instructions]
button to begin output
calibration and enable the Output [Zero] and [Full-Scale] buttons.
First adjust your input signal as necessary to drive the output
signal to precisely the nominal output zero of your selected
output range (i.e. -20.000mA, 0mA, 4.000mA, -10V, -5V, or 0V,
depending on the output range setting). Be sure to measure this
output level accurately, or performance will be degraded. After
driving the output to precisely output range zero, click the
Output
[Zero]
button of the Calibration Output section to
calibrate the output zero signal level.
Next adjust your input signal as necessary to drive the output
signal to precisely the nominal full-scale of your selected output
range (i.e. 20.000mA, 5V, or 10V, depending on the output range
setting). Be sure to measure this output level accurately, or
performance will be degraded. After driving the output to
precisely output range full-scale, click the Output
[Full-Scale]
button of the Calibration Output section to calibrate the output
full-scale signal level.
If your output acts erratic or appears imprecise, you may need to
repeat input or output calibration, being very careful to take
accurate measurements and input correct signal levels. For
current outputs, if you are measuring a voltage across an output
load resistance, make sure that you use the exact load resistance
when calculating the load current being measured. When
rescaling your input to a smaller sub-range, make sure that you
still have adequate input span, as too-tight input spans have
diminished resolution and will magnify error.
Factory Settings
You can use the
[Restore Factory Calibration]
button to restore
the transmitter’s original factory calibration if you think you
made an error during recalibration, degraded its performance, or
the I/O channel appears erratic.
You can use the
[Restore to Factory Default]
button to return the
unit to its original factory configuration settings. This does not
restore calibration, only configuration. Alternately, this button
can be used as a sanitation tool to restore the unit to its initial
configuration when decommissioning a module.
Calibration Status
This field displays calibration status messages like “No Error”,
“Transfer Error”, and “Timeout Error” during calibration. If you
encounter a Transfer or Timeout Error, your calibration did not
complete and you may have to repeat the calibration process.
