Chapter 1 - INTRODUCTION 1.1 PRELIMINARY EXAMINATION Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any noticeable damage, notify your Dealer or the nearest Hanna Customer Service Center immediately. HI9828 is supplied complete with: - Multisensor probe (pH/ORP, Conductivity, D.O.
1.3 GENERAL DESCRIPTION HI 9828 is a multiparameter system that benefits from years of experience of Hanna Instruments as a manufacturer of analytical instruments. Waterproof, resistant and easy to use, it is the ideal solution for field measurements of lakes, rivers and sea.
1.4 POWER SUPPLY HI9828 runs with 4 rechargeable C size, Ni-MH batteries. On the display the battery symbol visualizes the remaining battery charge. When this symbol starts blinking, it is necessary to recharge or replace them with new ones. When the batteries are completely rundown the meter automatically shuts off to avoid wrong readings. 1.4.1 Batteries installation Battery replacement must only take place in a nonhazardous area.
Cigarette lighter supply To recharge HI9828 from a vehicle cigarette lighter supply, use HI710046 HI710046. • Simply connect the cable to the meter and to the car’s cigarette lighter. • The message “Battery charging in progress” appears on the display, followed by the battery symbol. • A complete batteries recharging will last about 14 hours. NO TE NOTE Batteries can also be recharged with the meter ON; if the auto-off feature is enabled, the meter turns off automatically after the set time. 1.
Since the Pt/PtO system depends on the pH, the pretreatment of the electrode may be determined by the pH and the redox potential values of the solution to be measured. As a general rule, if the ORP (mV) reading corresponding to the solution pH value is higher than the values in the table below, an oxidizing pretreatment is necessary; otherwise perform a reducing pretreatment.
1.5.3 D.O. sensor activation The D.O. probe is shipped dry. To hydrate the probe and prepare it for use proceed as follows: • Remove the black & red plastic cap. This cap is used for shipping purposes only and can be thrown away. • Insert the supplied O-ring in the membrane. • Rinse the supplied membrane with electrolyte while shaking it gently. Refill with clean electrolyte. Gently tap the membrane over a surface to ensure that no air bubbles remain trapped.

Chapter 4 - CALIBRATION MODE HI9828 allows to perform six different types of calibration, one for each parameter and also a quick single-point calibration for some parameters. The calibration data are stored in the non volatile probe memory, so that the same probe can be used with different meters without needing recalibration. • To perform a calibration, select “Calibration” in the main menu with the arrow keys and then press OK.
• When the measure is stable, “Ready” is shown. Press CONFIRM to store the value. • The messages “Storing data on probe, please wait...” and “Updating GLP data, please wait ...” appear. NO TE If pH calibration is not required, the meter allows to skip to the EC quick NOTE calibration, by pressing the SKIP soft key. If the pH sensor is missing the message “pH sensor not installed! Skip to conductivity calibration” appears. • After the pH calibration is completed, the “Conductivity” option will blink.
4.2 pH CALIBRATION Calibrate the meter often, especially if high accuracy is required. Selecting pH calibration the display shows two options: “Calibrate pH” and “Clear old calibration”. If “Calibrate pH” is selected, it is possible to perform a new calibration at 1, 2 or 3 points with standard buffers (pH 4.01, 6.86 or 7.01, 9.18 or 10.01) or a single calibration with custom buffer. If “Clear old calibration” is selected, all calibration data will be deleted and the default data restored.

4.2.3 Error list If the meter does not accept a pH calibration point, a short message is displayed to indicate the possible error source. See for example the following screens: These are the available messages: • “Input out of scale”: the pH value is out of scale. • “Wrong buffer”: this message means that the difference between the pH reading and the selected buffer is too big. Check if the proper calibration buffer has been selected.
4.3 DISSOLVED OXYGEN CALIBRATION If D.O.% saturation range is calibrated, D.O. concentration range will also be calibrated, and vice-versa. The D.O.% saturation value is referred to the D.O. concentration in air (100%). For this reason it is recommended to calibrate the probe near the area where the measurements will be taken. Also note that the D.O. concentration values are based on D.O.% saturation, temperature, salinity and atmospheric pressure.
• Press CONFIRM to store the calibration point. • The following messages will appear: “Storing data on probe, please wait...”, “Updating GLP data, please wait ...” and “Calibration completed”. • Press OK to return to the calibration menu. • To return to the main menu, press ESC repeatedly.
