PROGRAMMING FOR pH MEASUREMENTS
12. The rFH prompt appears. Use the editing keys to change the display to the desired ref- erence electrode high impedance fault value. The allowed ranges are
Type of reference electrode | Allowed range | |
Low impedance (LO in step 11) | 0 | - 2000 kilohms |
High impedance (HI in step 11) | 0 | - 2000 megohms |
Entering 0000 disables the feature. When the reference electrode impedance goes above the fault value, the transmitter displays the diagnostic message rEFFAIL and sets a fault condition. Press ENTER to save.
13. The rWH prompt appears. Use the editing keys to change the display to the desired ref- erence electrode high impedance warning value. The allowed ranges are
Type of reference electrode | Allowed range | |
Low impedance (LO in step 11) | 0 | - 2000 kilohms |
|
|
|
High impedance (HI in step 11) | 0 | - 2000 megohms |
Entering 0000 disables the feature. When the reference electrode impedance goes above the fault value, the transmitter displays the diagnostic message rEFWArn. Press ENTER to save.
14. The rWL prompt appears. Use the editing keys to change the display to the desired ref- erence electrode low impedance warning value. The allowed ranges are
Type of reference electrode | Allowed range |
Low impedance (LO in step 11) | not applicable |
High impedance (HI in step 11) | 0 - 900 megohms |
Entering 0000 disables the feature. When the reference electrode impedance goes below the warning value, the transmitter displays the diagnostic message rEFWArn. Press ENTER to save. The prompt appears but is disabled when LO is selected in step 11.
15.The rFL prompt appears. Use the editing keys to change the display to the desired ref- erence electrode low impedance fault value. The allowed ranges are
Type of reference electrode | Allowed range |
Low impedance (LO in step 11) | not applicable |
|
|
High impedance (HI in step 11) | 0 - 900 megohms |
Entering 0000 disables the feature. When the reference electrode impedance goes below the fault value, the transmitter displays the diagnostic message rEFFAIL and sets a fault condition. Press ENTER to save. The prompt appears but is disabled when LO is selected in step 11.
16. Press EXIT to return to the process display.
