7.1 QUICK CALIBRATION
The quick calibration method provides a quick single point calibration for pH,
conductivity and dissolved oxygen sensors. HI 9828-25 calibration solution is
used for both pH and conductivity.
• Fill the calibration beaker 2/3 full with HI 9828-25 calibration solution.
• Slowly place the sensors into the solution and
dislodge bubbles that may adhere to the sensors.
• Screw the calibration beaker completely on the
probe body. Some solution may overflow.
• Wait a few minutes for the system to stabilize.
• From the “Calibration” menu select “Quick
calibration”.
• A three item calibration menu will appear (pH,
Conductivity and Dissolved oxygen) and “pH”
will start to blink along with the “Not ready”
message.
• When the pH signal is stable, the “Ready”
message appears. Press <Confirm> to store the
calibration data.
• The “Storing” message will appear as the
calibration proceeds to the next sensor. A
checkmark will appear in the box next to “pH” to
indicate a successful calibration.
Note Note Note Note Note To bypass any of the calibrations press
<Skip> to move to the next sensor in the
quick calibration menu.
If the pH sensor is not installed the message
“pH sensor not installed! Skip to
conductivity calibration” will appear.
• Following the pH calibration, “Conductivity” will start to blink along with the
“Not ready” message.
• When the measurement is stable, “Ready” appears. Press <Confirm> to store
the calibration data and the “Storing” message will appear.
Note Note Note Note Note If EC calibration is not required, skip to
the D.O. quick calibration by pressing the
<Skip> softkey.
• The message “Empty the beaker.” will appear.
