4.1 One-point standardization based on a grab
sample
Complete the following steps to perform a one-point calibration against an off-line
sample. This procedure is written for a Rosemount
™
56 transmitter.
Procedure
1. Press ENTER on the transmitter.
2. Select "S1 Measurement" or "S2 Measurement", depending on which sensor you
wish to standardize.
3. Select "Standardize (grab)" in the Calibration menu.
4. Once the pH reading of the sensor is stabilized, press
ENTER
to pass the installation
prompt.
5. Input the pH of the grab sample into the "pH of grab sample" field and press ENTER .
6. Press EXIT to complete the calibration.
The pH reading on the screen should now equal the pH of the grab sample.
Note
pH is a temperature dependent attribute. Please ensure off-line sample is at the same
temperature as the process, so that no errors in standardization occur.
