Page 27: Do Calibration
There are three calibration functions and procedures that can be accessed through the CAL button. These are calibration of the probe (DO), calibration of the barometer (Pressure) and calibration of the temperature (Temp). Prepare the dissolved oxygen probe according to the instructions from GETTING STARTED (page 11). - Page 28 For 100% calibration, water‑saturated air is the simplest method (and recommended method). It involves suspending the probe over a contained surface of water or moistened absorbent material. The temperature element should also be inside the container. Under equilibrium conditions, the partial pressure of oxygen in air‑saturated water is equal to the partial pressure of oxygen in water‑saturated air;...
- Page 29 The DO calibration screen will be displayed and the standard 0% saturation (or 0 mg/L, depending on the currently selected measuring unit), will be automatically selected. When the reading is stable within the acceptable range, the CFM functional key is displayed. Press CFM to confirm the calibration point.
- Page 30 Two points automatic calibration at 0% saturation (0 mg/L) and 100% saturation (8.26 mg/L) Note: if performing the two point calibration, the 0 point must be done first. Submerge the probe into HI7040 zero oxygen solution and stir gently for 2‑3 minutes. Press CAL.
- Page 31 Single point manual calibration Determine the dissolved oxygen value of the sample using a reference method such as the Winkler titration. Place the HI764113 probe in a sample, lake, basin, stream etc. that a recent dissolved oxygen determination has been made. The probe should be at thermal equilibrium with the sample. Press CAL.

Page 32: Pressure Calibration
Pressure calibration HI98198 meter incorporates a pressure transducer that accurately tracks local barometric pressure. Oxygen partial pressure is influenced by the local barometric pressure as dictated by Henry's Law. HI98198 automatically compensates dissolved oxygen measurements for these changes. The HI98198’s pressure transducer is factory calibrated and no user calibration should be necessary. If the pressure reading appears out of tolerance, the pressure reading can be checked and a calibration performed if required. -
Page 33: Temperature Calibration
To clear the pressure calibration and restore the factory one, press CAL from any measure mode (DO, BOD, OUR or SOUR). The calibration menu will be displayed. Press the Pressure functional key and then Clear. The user calibration will be removed and the factory calibration restored. Press ESC key at any time to exit the calibration without changing values. - Page 34 Use the keys to set the calibration point values to that of the reference thermometer. When available, CFM will appear on the display. Press CFM to complete the calibration. To clear the user temperature calibration at any time, press CAL from any measure mode (DO, BOD, OUR or SOUR).

Page 53: Probe Maintenance
PROBE MAINTENANCE Cleaning the HI764113 Probe Body • Rinse the probe with clean water to remove debris from around the probe body; wipe with a soft cloth. Unscrew and remove the protective shield and set aside. Ensure weeds, debris, or other materials are not coating the protective guard as this will block sample circulation preventing sample from reaching the active measurement surface. - Page 54 1. Unplug the HI764113 from the HI98198 meter. Remove the stainless steel guard from probe body and set aside. Wipe off the probe and cap with a soft tissue. 2. Remove the expired “Smart Cap™” from the probe; Squeeze the used cap at the notched V and pull it off the probe body (without twisting).
