The dates shown to the right of the screen are the dates of the last successful calibration.
The value shown on the bottom line next to ‘EC’ is the value the EC electrode was last
calibrated to.
7.
Move the pointer down to the bottom line using the down arrow key.
Calibration
DOZero?[01/Jan/09]
DO100%?[01/Jan/09]
EC2570?[01/Jan/09]
If the Calibration Standard value you are using is already displayed, press the
OK
key to
start calibrating. Remember, if you are using RapidCal solution, the EC value on this line
should be 2570.
If the value of the EC Calibration Standard you are using is not displayed, press the right
arrow key. The bottom line will change to:
Calibration
DOZero?[01/Jan/09]
DO100%?[01/Jan/09]
EC
2570?[01/Jan/09]
You can now use the up and down arrow keys to select one of three EC Calibration
Standard values (1413, 2570 or 12880).
8.
Once the correct Calibration Standard value is being displayed, press the
OK
key. The screen will change to:
PLEASE WAIT
Stabilising
000%
9.
When the ‘Calibrating 100%’ screen is displayed, press OK.
Special Notes:
If you have selected a Calibration Standard value other than 2570 (RapidCal),
then you subsequently use the RapidCal calibration technique described in
section 10, the Calibration Standard value will automatically be reset to 2570.
The Calibration Standard value is stored in the Probe,
not
the Meter. If you
use one Meter with several different Probes, you will have to set the
Calibration Standard value for each probe individually during calibration.
If you select a Calibration Standard value but do not press
OK
, the
information will not be sent to the Probe and the change will not be registered.
14.10. Verifying EC Calibration
Due to the fact that debris and air bubbles can adversely affect EC calibration, it is
essential to verify calibration has been properly achieved. To do this, follow item nine
above with this procedure.
