Calibration
The Analog Output signal is calibrated using an
appropriate current or voltage meter. Calibration is
performed in the two analog output calibration
menus (Ao O and Ao S) on the Input Page.
1. Connect the meter to the analog process output
terminals. To calibrate the analog output, the
output must be forced to the low end of span. If
the setpoint is selected for transmission
(CTRL PAGE, AOUT = ASP) this can be done by
adjusting the setpoint to the low end of span
(i.e. J T/C = -100°F).
2. Go to menu AO O. Adjust the Analog Output
(using ▲ and ▼) until the meter reads 4mA or
1.000 Vdc.

4. Go to menu AO S. Adjust Analog Output
(using ▲ and ▼) until the meter reads 20mA or
5.000 Vdc.
