Calibrate Your Output
Modules

Output calibration is a multi-step process that involves measuring a signal
from the module. This section has two parts, as shown in the table.

The 1756-OF4 and 1756-OF8 modules can be calibrated for current or
voltage applications.

The 1756-OF6CI module, however, must be calibrated for current only, while
the OF6VI must be calibrated specifically for voltage.

Current Meter Calibrations

RSLogix 5000 software commands the module to output specific levels of
current. You must measure the actual level and record the results. This
measurement allows the module to account for any inaccuracies.

The 1756-OF4, 1756-OF8, and 1756-OF6CI modules use basically the same
procedures for being calibrated by a current meter.

While you are online, you must access the Module Properties dialog box.
