NOTE: During calibration, the analog output is automatically “held” at the last measured
value.
7. After a screen like
appears, use arrow keys to adjust the
slope value to match the
known slope of the reference solution, and press ENTER key
to enter the value.
NOTE: Measured values are normally compensated using the configured temperature
compensation method. However, during calibration the measured value is linearly
compensated by the entered reference temperature and slope value of the reference
solution.
8. With the sensor in solution and the
screen displayed, press
ENTER key to confirm. This active screen appears
showing the measured reference solution value.
9. Wait for the reading to stabilize which may take up to 30 minutes. Then press ENTER
key. The “PLEASE WAIT” screen may appear if the reading is still too unstable. After
the reading has stabilized, this
static screen appears
showing the “last measured” value.
10. Use arrow keys to adjust the “last-measured” value to exactly match the known value
of the reference solution.
11. Press ENTER key to enter the value and complete calibration (“CONFIRM CAL OK?”
screen appears).
12. Re-install the sensor into the process.
13. Press ENTER key to display the active measurement reading on the “CONFIRM
ACTIVE?” output status screen. When the reading corresponds to the actual typical
process value, press ENTER key again to return the analog output to its active state
(MEASURE screen appears).
This completes COND CAL calibration
SAMPLE CAL Method
The “SAMPLE CAL” method enables the sensor to remain installed in the process.
1. Obtain a sample of the process solution and determine its value using laboratory
analysis or a recently calibrated portable meter.
2. Press MENU key to display a “MAIN MENU” screen. If the
screen is not showing, use
