User Guide

The use of a magnetic stirrer to ensure a certain velocity of the fluid is

recommended.

Always allow a few minutes for thermal equilibrium to occur

between the probe and the measurement sample.

TAKING TEMPERATURE MEASUREMENTS

The probe has a built-in temperature sensor.

The measured temperature is indicated on the secondary display.

Allow the probe to reach thermal equilibrium before taking any measurement.

Reaching thermal equilibrium can take several minutes. The greater the

difference between the temperature at which the probe was stored and the

temperature of the sample, the longer the time will be.

If “----” is displayed, it indicates that the D.O. probe is not properly connected

or the temperature is out of range. This also indicates the possibility of a

broken probe cable.

D.O. CALIBRATION

For greatest accuracy, it is recommended that the instrument is calibrated

frequently.

The standard calibration program of the meter is prepared for 2 (maximum)

values: 0.0% (zero calibration) and 100.0% (slope calibration).

The next logging will start from page 16.

INTERFACE WITH PC

Data transmission from the instrument to a PC is now much easier with the

new HI 92000 Windows

compatible software (optional).

User friendly, HI 92000 offers a variety of features and has on line help to

support you throughout all situations.

HI 92000 allows you to use the powerful means of the most popular spread

sheet programs (e.g. Excel

, Lotus 1-2-3

). Simply run your favorite spread

sheet and open the file downloaded by HI 92000. It is then possible to make

any elaboration available with your software (e.g. graphics, statistical analy-

sis).

To install HI 92000 you need a 3.5" drive and few minutes to follow the

instructions conveniently printed on the disk’s label.

To connect your HI 2400 to a PC, use HI9 20010, available through your

Hanna Dealer. Make sure that your meter is switched off and plug the

connectors, one into the meter RS232C connector, the other into the serial port

of your PC.

Note: Cables different from the HI 920010 may use a different configuration.

In such case any communication between the meter and the PC is not

possible.
