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 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 To bypass any of the calibrations press

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 to store

the calibration data and the “Storing” message will appear.

Note

If EC calibration is not required, skip to
the D.O. quick calibration by pressing the
softkey.

• The message “Empty the beaker.” will appear.
