Conventional calibration with any buffers: "ConCal"
Conventional two point calibration: "ConCal"
Course of the calibration process:
Submenu "ConCal":
2 channel instruments display the selected
channel, e. g. A.
With
start calibration.
"Freezing" of the recorder output and the
relays.
With
quit and go to submenu
"CALIB B".
Rinse electrode and immerse it into a neutral
buffer solution.
pH value of the solution 7.0 ± 0.5.
With
start calibration.
If the temperature compensation has been configured to manual input (Configuration: T-C
MANUAL) the following is displayed:
With
set temperature of buffer
solution 1.
(Default value 15°C).
With
accept and start calibration.
Set offset voltage ("Asymmetry" ASY):
With
set pH value of buffer solution 1.
Attend to temperature of the solution!
With
accept.
