The adjacent screen appears. To
Calibrate
pH or Temperature scroll to the
desired item and press
ENTER
.
The following sub-sections show the initial display screen that appears for each calibration routine.
Use the flow diagram (
Figure 7-1
) for pH calibration at the end of this section and the live screen
prompts to complete calibration.
7.2.2
Auto Calibration - pH
This screen appears after selecting
pH cal.
Note that pH auto calibration criteria can be changed.
The following criteria can be adjusted:
•
Stabilization time (default 10 seconds)
•
Stabilization pH value (default 0.02 pH)
•
Type of Buffer used for AUTO CALIBRATION (default is Standard, non-commercial buffers).
The following commercial buffer tables are recognized by the analyzer:
•
Standard (NIST plus pH7)
•
DIN 19267
•
Ingold
•
Merck
The adjacent screen appears to allow adjustment of above criteria:
The adjacent screen appears if the
Auto Cal
is successful. The screen returns
to the
pH Buffer Cal
menu.
The following screen appears if the
Auto Cal
is unsuccessful.
