Data transmission from the instrument to the PC can be done with
the
HI 92000
Windows
®
compatible software (optional).
HI 92000
also offers graphing and on-line help feature.
Data can be exported to the most popular spreadsheet programs for
further analysis.
To connect your instrument to a PC, use the optional Hanna
HI 920010
cable connector. Make sure that your instrument is switched off and
plug one connector to the instrument RS232C socket and the other into
the serial port of your PC.
Notes:
• Other cables than
HI 920010
may use a different
configuration. In this case communication between in-
strument and PC may not be possible.
• If you are not using Hanna Instruments
HI 92000
software, please see the following instructions.

• To set the instrument baud rate, press
COMM
while in measurement mode. The primary LCD
will show the current
baud rate
.
• Use the
ARROW
keys to change the displayed value (150; 300;
600; 1200; 2400 – factory setting; 4800; 9600).
• Press
CFM
to confirm. The primary LCD will show the current

(factory setting is 16).
• Use the
ARROW
keys to change the displayed value (between 0
and 47).
• Press
CFM
to confirm. The meter returns to
measurement mode.
Note:
The command prefix must not be changed if

All the instruments are factory calibrated for mV.
Hanna’s ORP electrodes are interchangeable and no mV calibration
is needed when they are replaced.
If the mV measurements are inaccurate, mV recalibration should be
performed.
For an accurate recalibration, contact your dealer or the nearest
Hanna Customer Service Center, or follow the instructions below.
A two or three-point calibration can be performed at 0.0 mV, 600.0
mV and 1800.0 mV.
• Attach to the BNC connector a mV simulator with an accuracy of
±0.1 mV.
• With the instrument off, press and hold down the
MR&CFM
keys, then power on the instrument. The “CAL” tag will appear
and the secondary LCD will show 0.0 mV.
• Set 0.0 mV on the simulator.
When the reading is stable and close to the selected calibration
point, “READY” tag will appear and “CFM” tag will blink.
• Press
CFM
to confirm. The secondary LCD will display 600 mV.
• Set 600.0 mV on the simulator.
When the reading is stable and close to the selected calibration
point, “READY” tag will appear and “CFM” tag will blink.
• Press
CFM
to confirm. The secondary LCD will display 1800 mV.
• Set 1800.0 mV on the simulator.
When the reading is stable and close to the selected calibration
point, “READY” tag will appear and “CFM” tag will blink.
• Press
CFM
to confirm. The
instrument
returns to measurement
mode.
Notes:
• If the reading is not close to the selected calibration point,
“WRONG” tag will blink. Verify calibration condition or
contact your vendor if you can not calibrate.
• Press
CAL
in any moment of the calibration process. The
instrument will return to measurement mode. If calibra-
tion process is stopped after 600 mV is confirmed, the
600 mV range is calibrated and calibration parameters
are memorized.
