[. . . ] · When the "12. 88 mS" stops blinking, indicating that the measurement has stabilized, press the CFM key again to confirm the fourth calibration point. mS CFM · If the value is out of the slope range, an "E3" error message will appear on the secondary display. Press the CAL key to re-calibrate the value. CAL · If everything is satisfactory the LCD will blink "80. 0 mS", expecting the next calibration solution (HI 7034 or HI 8034) · Wait for 1 minute, then immerse the probe into the HI 7034/HI 7034 calibration solution. 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). Place insulation material around the containers to minimize temperature changes. Use a ChecktempC or a calibrated thermometer with a resolution of 0. 1° as reference thermometer. °C °C 0 °C (32 °F) 50 °C (122 °F) Note: After performing the following calibration, conductivity must be recalibrated. PROCEDURE · Press the RANGE key to select the temperature measurement mode (just temperature measurement on the primary display). °C RANGE · Ensure that the probe is connected to the meter securely by aligning the pins with the socket, pushing the plug in and tightening the threaded ring. Insert the probe 27 into the PVC sleeve with the holes towards the top (the end nearest to the cable) of the probe. °C · Place the probe into the container with ice and water (0. 0°C/32°F). 0 °C (32 °F) · Press the CAL key. The secondary (lower) display will blink "0" for about 30 seconds. CAL · When "0" stops blinking, the calibration can be confirmed. Press the CFM key to confirm the first value. CFM · If the value is out of the offset range, an error message will show on the secondary display "E1". Press the CAL key to recalibrate the value. CAL 28 · If everything is satisfactory the LCD will blink "50" expecting the second buffer (50°C/122°F). Note: if a single point calibration is required, press the CAL key to leave the calibration mode now. CAL °C · Place the probe into the second container with hot water (50°C/122°F). 50 °C (122 °F) · When "50" stops blinking, press the CFM key again to confirm the second calibration point. CFM · If the value is out of the slope range, an error message will show on the secondary display "E2". Press the CAL key to recalibrate the value. CAL · If everything is satisfactory the temperature calibration is complete and the meter will return to the normal operational mode. 29 PRINTING/RECORDING WITH HI933301 To print the measured values press the PRINT key. The printout provides the following information: PRINT a - Running log number b - Date (DD-MM-YY) c - Time (HH-MM) d - Conductivity value in µS/cm or mS/cm e - Temperature in degrees Centigrade. a b c d e 29-03-96 --01-*15. 01 147. 6 µS 25. 1 °C RECORDING MODE (PROGRAMMED PRINTOUTS ) Set the appropriate printing interval (see Operational Guide section on page 12). Press the ALT and the RECORD keys simultaneously to enter the recording mode. The log number will appear for a few seconds on the display to indicate the correct operational mode. ALT CAL CFM RANGE PRINT RECORD LOG INTV The meter will print the measurement taken at that moment and will continue to print according to the set interval until the recording function is stopped (see below). 30 Each printout provides the following information: a - Running log number. c - Date (DD-MM-YY) d - Printing interval indicator in minutes e - Time (HH-MM) f - Conductivity value in µS/cm or mS/cm g - Temperature in degrees Centigrade. a b 29-03-96 --01-<> c d e f g 0001M *16. 59 5137 µS 25. 9 °C 0015 When the meter is in the recording mode "LOG" is displayed on the bottom left corner of the LCD. TIME LOG INTV If no keys are pressed, the meter goes to standby mode to prolong the battery life. [. . . ] Press the PAPER key to reset the printer. PAPER 47 PROBE MAINTENANCE Rinse the probe with tap water after every series of measurements. If a more thorough cleaning is required, remove the PVC sleeve and clean the probe with a cloth or a nonabrasive detergent. When reinserting the sleeve onto the probe, be sure that the sleeve is in the right direction with the four holes towards the cable end. The probe body is in PVC and for this reason must never come into close contact with sources of heat. [. . . ]
