Each HI2400 bench D.O. meter comes supplied complete with:
HI 76407/2 D.O. probe with 2 m (6.7') cable
HI 76407A membrane cap (2 pcs)
HI 7041S electrolyte solution (30 ml)
• 12 VDC power adapter (HI 710005 or HI 710006)
Note: Save all packing material until you are sure that the instrument
functions correctly. All defective items must be returned in the original packing with the supplied accessories.
GENERAL DESCRIPTION
HI 2400 is a microprocessor-based, logging bench meter for Dissolved Oxygen measurements.
It can store in memory up to 99 lots with up to 8000 readings. These readings can be transferred to a computer system for elaboration or permanent storage.
Dissolved Oxygen is indicated in ppm (parts per million) or in %. Temperature is compensated for by the meter’s ATC circuitry. Salinity compen-
sation in water allows direct determination of Dissolved Oxygen in saline waters and the altitude compensation readjusts for the altitude variance.
The Dissolved Oxygen probe has a membrane covering the polarographic sensors and a built-in thermistor for temperature measurements and compen­sation.
This permeable Teflon®membrane isolates the sensor elements from the test­ing solution, but allows Oxygen to pass through. When a voltage is applied across the sensor, oxygen that has passed through the membrane reacts causing a current flow, and hence determining a reading.

sample no. 1 —— send ppm data if ppm is log selected —— send % data if % is log selected —— send temperature data if temperature is log selected sample no. 2 ... until the last sample sample “XXX” is signed hex format.
15) last sample time, min. E.g. “59” for 59 minute
16) last sample time, hour. E.g. “12” for 12 hour
17) last sample time, day. E.g. “09” for 9th day
18) last sample time, month. E.g. “09” for September
19) last sample time, year. E.g. “96” for year 1996
20) etx end
The meter will send “Err6” if in a different measurement range.
Commands setting parameters:
/ML To select the data lot for data transfer.
E.g. send “/ML05” to select lot no. 5. If the lot no. is valid, the meter will send <ACK>, otherwise it
will send <CAN>. /BR To set the RS232C baud rate.
E.g. send “/BR0” to set the meter to baud rate of 150 send “/BR1” to set the meter to baud rate of 300 send “/BR2” to set the meter to baud rate of 600 send “/BR3” to set the meter to baud rate of 1200 send “/BR4” to set the meter to baud rate of 2400 send “/BR5” to set the meter to baud rate of 4800 send “/BR6” to set the meter to baud rate of 9600
/PF To set the RS232C command prefix.
E.g. send “/PF05” to set the command prefix to 05.
Note: <ACK> will be sent by the meter if the command received is ac-
cepted, otherwise it will send <CAN>.
<ACK> equals to ASCII code 06 and <CAN> equals to
ASCII code 24.
If sample data is out of range “07FFFH” is sent.
These commands may be sent with either capital or small letters. Invalid commands will be ignored. The characters sent by the pH meter are always capital letters.
