The level of solution must be higher 24 0 703 HI mS 8 cm (3¼") 4 703 HI than the holes on the PVC sleeve. Tap the probe repeatedly on the bottom of the beaker and stir it to ensure that no air bubbles are trapped inside the sleeve. · When the "80. 0 mS" stops blinking, indicating that the measurement has stabilized, press the CFM key again to confirm the fifth calibration point. mS CFM · If the value is out of the slope range, an "E4" error message will appear on the secondary display. Press the CAL key to re-calibrate the value. CAL · If everything is satisfactory the calibration ends and the meter will return to the normal operational mode. Note: · If the instrument will not calibrate refer to the Probe Maintenance and Cleaning section (see page 48). · It is always possible to quit the calibration mode by pressing the CAL key.

"1413 µS" using HI 7031 or HI 8031 as calibration solution. 26 TEMPERATURE CALIBRATION (for Technical Personnel only) INITIAL PREPARATION Prepare a container of ice and water and another container with hot water (at a temperature of at least 50°C/122°F). [. . . ] The probe body is in PVC and for this reason must never come into close contact with sources of heat. If the probe is exposed to high temperatures, detachment of the rings might occur, resulting in a serious impairment of probe function. In such cases, the probe has to be replaced. 48 BATTERY REPLACEMENT When the batteries are run down "LOBAT" is displayed on the Liquid Crystal Display to warn the user. Battery replacement must only take place in a non hazardous area using 1. 5V alkaline AA type batteries. [. . . ]
