8. The rWH prompt appears. In the display, W appears as wj. Use the editing keys
to change the display to the desired reference electrode high impedance warn-
ing value. The allowed ranges are
Type of reference electrode Allowed range
Low impedance (LO in step 6) 0 - 2000 kilohms
High impedance (HI in step 6) 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.
9. The rWL prompt appears. Use the editing keys to change the display to the
desired reference electrode low impedance warning value. The allowed ranges are
Type of reference electrode Allowed range
Low impedance (LO in step 6) not applicable
High impedance (HI in step 6) 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 6.
10. The rFL prompt appears. Use the editing keys to change the display to the
desired reference electrode low impedance fault value. The allowed ranges are
Type of reference electrode Allowed range
Low impedance (LO in step 6) not applicable
High impedance (HI in step 6) 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 6.
11. Press EXIT to return to the process display.
