Chapter 4 - CALIBRATION MODE

HI9828

HI9828 allows to perform six different types of calibration, one for each pa-
rameter, and a quick single-point procedure for some of them.

Calibration data are stored in the non volatile memory of the probe, so that the
same probe can be used with different meters without needing new calibration.

• To perform a calibration procedure, select the

“Calibration” option from the main menu and
press .

Note

If password protection is enabled and
the latest performed action was a not
password protected feature, the meter
will ask to insert the password.

• Select the desired calibration type with the arrow keys and then press .

Available options are:
Quick calibration (single point procedure to calibrate DO saturation, pH and
conductivity ranges), pH, DO, conductivity, atmospheric pressure, ORP and tem-
perature.

4.1 QUICK CALIBRATION

The quick calibration feature allows a fast and easy field calibration of the
multisensor probe, using only one solution (HI9828-25

HI9828-25

HI9828-25).

• Fill the calibration beaker with the HI9828-25

HI9828-25

HI9828-25 calibration solution.

• Screw the calibration beaker on the probe body. Some solution will overflow.
• Wait a few minutes for the system to stabilize.

• Select the “Quick calibration” option from the

“Calibration” menu and press .

• A 3-item (pH, Conductivity and Dissolved oxy-

gen) screen appears. “pH” starts blinking and
the “Not ready” message is shown.
