17. Press STORE.
18. For verification perform the following steps:
1) Press STEP UP button. Rotate Pulser Knob to select 'CAL VIEW' parameter.
2) Press STEP DOWN button to enter VALUE level. Set precision voltage source to zero input voltage. The
display should read 0%.
3) Set source to full scale voltage. The display should read 100%.
20. If all points have been calibrated and verified, press EXIT button to leave the calibration mode and enter the
operation mode. If additional function blocks are to be calibrated and verified, press the STEP UP button to
enter the FUNCTION BLOCK level. Perform steps 2 -19 for each function block.
If security is enabled, exiting the configuration mode will lock out the calibration mode until the security
combination is re-entered.

12.2 ANALOG OUTPUT (AOUT1-3)

Analog output function blocks have been factory calibrated to 4-20 mAdc outputs. If recalibration is necessary use
the following procedure.
1. At the controller's rear terminals, connect an electronic calibrator or digital multimeter capable of displaying
4.00 and 20.00 mAdc to the selected analog output terminals (AOUT1 or AOUT2). Refer to Section 8
Installation for terminal numbers and wiring guidelines. Ensure that terminal screws are tight.
2. If security is enabled, a level 1 or level 4 security combination will be needed to store the results of a
calibration. Refer to SECUR-Security in Section 3 for additional information.
3. Apply power to the station.
4. Press the ENTER CONF button to enter the configuration mode at the MENU level.
5. Rotate the Pulser Knob to select 'STATION' on the alphanumeric (lower) display.
6. Press the STEP DOWN button to choose options at the station level and rotate the Pulser Knob to select 'CAL'
on the alphanumeric display.
7. Press the STEP DOWN button to enter the FUNCTION BLOCK level. Rotate the Pulser Knob to select the
desired output (e.g. AOUT1).
8. Press the STEP DOWN button to enter the PARAMETER level. Rotate the Pulser Knob to select the desired
parameter, CAL ZERO, shown on the alphanumeric display.
9. Press the STEP DOWN button to enter the VALUE level ('CAL' appears on display).
10. Rotate the Pulser Knob to set the zero output to 4.00 mA on the digital multimeter or electronic calibrator.
11. Press the STORE button to lock-in the desired value. (If "ENTER COM" appears in the alphanumeric display,
go to Section 12.1, step 13 for entering a level 1 or level 4 security combination.)
12. Press the STEP UP button. Rotate the Pulser Knob to select the 'CAL FULL' parameter.
13. Press the STEP DOWN button to enter the VALUE level ('CAL' appears on display).
14. Rotate the Pulser Knob to set the full scale output to 20.00 mA.
15. Press STORE.
16. For verification perform the following steps:
1) Press STEP UP button and rotate Pulser Knob to select 'CAL VIEW' parameter.
2) Press STEP DOWN button to enter VALUE level.
3) Rotate Pulser Knob to set display to 0.0%. Output current should be 4.00 mA.
4) Rotate Pulser Knob to set 100.0%. Output current should be 20.00 mA.
