Procedure - In-Process Calibration Using Deltav - Emerson ROSEMOUNT 5081-A Instruction Manual

MODEL 5081-A
9.7 PROCEDURE — IN-PROCESS CALIBRATION USING Deltav
1. the transmitter and sensor can be calibrated against a standard instrument. For oxygen sensors installed in
aeration basins in waste treatment plants, calibration against a second instrument is often preferred. For an
accurate calibration be sure that:
a. the standard instrument has been zeroed and calibrated against water-saturated air following the manu-
facturer's instructions.
b. the standard sensor is inserted in the liquid as close to the process sensor as possible.
c. Adequate time is allowed for the standard sensor to stabilize before calibrating the process instrument.
2. 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.
