Page 10: Do Calibration
The instrument can be calibrated in maximum 2 points: 0.0% (zero calibration) and 100.0% (slope calibration). The zero calibration of the HI 2400 is very stable, therefore this procedure needs to be performed only whenever the probe or the membrane is replaced. - Page 11 ZERO CALIBRATION • Submerse the probe into HI 7040 zero oxygen solution and stir gently for 2-3 minutes. • Press CAL. The “~” and “ ” tags will blink on the LCD until the reading is stable. • When the reading is stable, “CFM” starts blinking. Press CFM to confirm the “0.0%”...
- Page 12 • If the temperature goes out of range during calibration the “WRONG”, temperature unit tag and both measurements will blink. • HI 2400 has automatic buffer recognition function. If the ARROW keys are pressed to select the desired calibration value, the automatic buffer recognition function is disabled.

Page 22: Temperature Calibration (For Technical Personnel Only)
If the temperature measurements are not accurate, temperature recalibration should be performed. For an accurate recalibration, contact your dealer or the nearest Hanna Customer Service Center, or follow the procedure below. • Prepare a vessel containing ice and water and another one containing hot water (at a temperature of around 50 °C). - Page 23 • Submerse the DO probe in the second vessel as near as possible to the reference thermom- eter. Allow a few seconds for the probe to stabilize. • Use the ARROW keys to set the reading on the secondary LCD to that of the hot water. •...

Important In order to have accurate and stable measurements, it is important that the membrane surface is in perfect condition. This semipermeable membrane isolates the sensor elements from the environment but allows oxygen to enter. If any dirt is observed on the membrane, rinse carefully with distilled or deionized water. -
