7.7.3 Procedure using the infrared remote controller
1. Press PRoG on the remote controller.
2. Press NEXt until the PH submenu appears. On will be flashing, indicating that the pH
measurement and automatic pH correction of free chlorine has been enabled.
to keep automatic pH correction enabled, press ENtER. Go to step 3.
to disable automatic pH correction, use é or ê to change On to OFF and press
ENtER. the MAn prompt appears. use the arrow keys to enter the pH of the sam-
ple. Press ENtER to save. Press RESEt to return to the main display.
3. the screen displays the PAMP (preamplifier) prompt. Press é or ê to toggle between
trAnS and SnSr.
trAnS Preamplifier is in the transmitter
SnSr Preamplifier is in the sensor or in a remote junction box
Press ENtER to save.
4. the screen displays the dIAgnOStIC submenu header. Prompts under this header
allow the user to change the reference offset and pH sensor diagnostic limits.
the default settings are:
to keep the default settings, press NEXt. Go to step 11.
to change the reference offset or to enable or make changes to the glass diagnostic
settings, press ENtER. Go to step 5.
5. the rOFFSEt (reference offset) prompt appears. use the arrow keys to change the
offset to the desired value in mV. Press ENtER to save.
6. the dIAg (diagnostics) prompt appears. Press é or ê to toggle between OFF (dis-
able) or On (enable). Press ENtER to save.
7. the IMPtC (glass impedance temperature correction) prompt appears. Press é or ê
to toggle between OFF (disable) or On (enable). Because glass impedance is a
strong function of temperature, correcting glass impedance for temperature effects is
strongly recommended. Press ENtER to save.
8. the GFH (glass fault high) prompt appears. use the arrow keys to change the set-
ting to the desired value. the default setting is 1000 MW. Entering 0000 disables the
feature. Press ENtER to save.
When the glass electrode impedance exceeds the limit, the transmitter displays the
GLASSFAIL diagnostic message and sets a fault condition.
9. the GFL (glass fault low) prompt appears. use the arrow keys to change the setting
to the desired value. the default setting is 10 MW. Entering 0000 disables the feature.
Press ENtER to save.
When the glass electrode impedance falls below the limit, the transmitter displays the
GLASSFAIL diagnostic message and sets a fault condition.
