2.2.2.5 Cal. History: Shows the diagnostic values of the last pH electrode
calibrations, offset in mV and slope in mV/pH.
2.2.3 Miscellaneous :
2.2.3.1
Case Temp:
Temperature in °C inside the transmitter.
2.3 Sample
2.3.1
 Sample ID
: Shows the identification assigned to a sample. This
identification is defined by the user to identify the location of the
sample.
 Temperature
: Actual temperature in °C and in Ohm
(NT5K).
 Sample Flow
: Shows the actual sample flow B/s (bubbles per
second). Sample flow must be above 5 B/s.
(Raw value) (Hz):
Shows the raw value in Hz.
2.4 I/O State
Shows current status of all in- and outputs.
2.4.1
2.4.2
2.5 Interface
Only available if optional interface is installed.
Shows the programmed communication settings.
3 Maintenance
3.1 Calibration
In this menu, you can correct measured values, or calibrate offset
and slope of pH electrode.
3.1.1 Standard Sodium: Possibility to correct the sodium sensor value.
Follow the commands on the screen. Save the value with the <En
-
ter> key. See Calibration, p. 76 , for more details.
3.1.2 Process pH: Correction of pH electrode. See pH Process Calibra
-
tion, p. 76 , for details.
