IST9147R2 05/05 PROBE PREPARATION All Hanna D.O. probes are shipped dry. To hydrate the probe and prepare it for use proceed as follows: 1. Remove the black & red plastic cap. This cap is used for shipping purposes only and can be thrown away. 2. Insert the supplied O-ring in the membrane (see figure). CALIBRATION Calibration is a very simple 1-point procedure, performed in air. Ensure the probe is ready for measurements, i.e. the membrane is filled with electrolyte (see "Probe Preparation" section for details). Switch the meter on, select the % mode and turn the % trimmer to display 100%. If the environmental relative humidity is lower than 30%, pour some deionized water (approx. 3 mm) in the white cap supplied with the membrane. Insert the probe in the cap and calibrate. Keep the probe in vertical position to avoid any contact of the membrane with the water. Note: For best accuracy, calibration should be performed on the measurement site, and the probe should be at the same temperature as the air. Note: After replacing the membrane or the electrolyte solution, wait a few minutes for the reading to stabilize. SALINITY COMPENSATION Oxygen measurements (mg/L range only) can be compensated for salinity factor and the correction value can be set by the user. Enter the mg/L mode by pressing the corresponding key. Keep the SAL button pressed while turning the SAL trimmer to display the desired salinity value (within the 0 to 51 g/L range). BATTERY RECHARGE & REPLACEMENT The instrument features a battery level control system: the "V" tag on the LCD lights up to advise the user that only a few hours of working life are left. The instrument is also provided with BEPS (Battery Error Preventing System), which turns the meter off if the battery level is too low to ensure reliable readings. The 9V battery provided with the instrument can be recharged using the optional HI 710040 battery recharger. Plug the recharger and the green LED will turn on, then put the meter on the recharger and the LED will turn to orange, to indicate that the battery is charging. ALTITUDE COMPENSATION When salinity compensation is not required (i.e. not salty water), the SAL trimmer can be used to set the altitude correction value.
