This is the actual pH calibration. The
initial display will be the chosen
buffer for
pH BUFFER I SELECT.
The
“STAND
” annunciator will
blink indicating the unit is waiting
for the user to start the calibration.
Put the cleaned electrode and
temperature probe in buffer I. Pressing the [
OK
] key will start the
calibration. For Detailed instructions please see
Step-by-Step pH
Calibration (step 7)
on the next page
.
v. SLOPE CALIBRATION screen
After finishing the Buffer I calibration
the unit will move to this screen. The
initial display will be the chosen
buffer for
pH BUFFER II SELECT.
The “
SLOPE
” annunciator will blink
indicating that the unit is waiting for
the user to continue the calibration.
Put the cleaned electrode and temperature probe in buffer II.
Pressing the [
OK
] key will start the calibration. For detailed
instructions please see
Step-by-Step pH Calibration
on the next
page.
vi. EFFICIENCY information screen
This screen will display the
efficiency of the pH electrode from
its last calibration. This screen is for
user information only and will
automatically change to the 4mA
setting after 4 seconds.
The equation of Efficiency is:
Efficiency = (new slope/ ideal slope) x 100%.
