Procedure - Full Scale Calibration Using Deltav - Emerson ROSEMOUNT 5081-A Instruction Manual

MODEL 5081-A
10.5 PROCEDURE — FULL SCALE CALIBRATION USING Deltav
1. Place the sensor in the process liquid. If automatic pH correction is being used, calibrate the pH sensor (see
Section 13.0) and place it in the process liquid. If manual pH correction is being used, measure the pH of the
process liquid and enter the value (see Section 7.8). Adjust the sample flow until it is within the range recom-
mended for the chlorine sensor. Refer to the sensor instruction sheet.
2. Adjust the chlorine concentration until it is near the upper end of the control range. Wait until the reading is
stable before starting the calibration.
3. Access: deltaV Explorer/Context Menu
Calibrate Amperometric Sensor (method_pv_cal)
Method Steps:
a. displayed: Current PV Measurement
Prompt: Is value stable?: Yes; No; Abort
If "No" is chosen, the PV measurement is re-read.
b. If "Yes" is chosen, the PV measurement and the new sensitivity value are shown.
the method concludes.
