  • Page 10: Operational Guide

    OPERATIONAL GUIDE CONNECTIONS • The meter is supplied complete with four 1.5 V AA alkaline batteries. Remove the rear cover, unwrap the batteries and install them while paying attention to the correct polarity (see “Battery Replacement” section). • Connect the DO probe to the DIN socket on the top of the instrument.
  • Page 11 bubbles remain trapped. To avoid damaging the mem- brane, do not touch it with your fingers. • With the sensor facing down screw the cap clockwise to the end of the threads. Some electrolyte will over- flow. INSTRUMENT START-UP • Turn the instrument on by pressing the ON/OFF button.
  • Page 12 SALINITY AND ALTITUDE COMPENSATION If the sample contains significant concentration of salin- ity or if you are performing measurements at an altitude different from sea level, the read out values must be corrected, taking into account the lower degree of oxygen solubility in these situations (see “Setup”...
  • Page 13 For accurate DO measurements, a water movement of 0.3 m/s is required. This is to ensure that the oxygen- depleted membrane surface is constantly replenished. A moving stream will provide adequate circulation. The use of a magnetic stirrer to ensure a certain fluid velocity is recommended.

  • Page 14: Do Calibration

    DO CALIBRATION It is recommended to calibrate the instrument fre- quently, especially if high accuracy is required. Before proceeding with the calibration, make sure the probe is ready for measurements (see “Probe prepa- ration” paragraph on page 10), i.e. the membrane cap is filled with electrolyte and the probe is connected to the meter and properly polarized.
  • Page 15 • Switch the meter on by pressing the ON/OFF key. • Remove the probe protective cap. • Set the appropriate altitude factor and set the salinity factor to zero (see “Setup” section for details). Zero Calibration • Submerge the probe into AD7040 zero oxygen solu- tion and stir gently for 2-3 minutes.
  • Page 16 Note: If you are performing a slope calibration only, press CAL and then use the ARROW keys to select the 100% DO calibration point. • Dry the probe tip and allow a few seconds for the reading to stabilize. The hourglass symbol will blink until the reading is stable.
  • Page 17 • Set the appropriate altitude factor and set the salinity factor to zero (see “Setup” section for details). Procedure • Submerge the probe into the custom solution. • Press CAL and then RANGE. The CAL tag and the “Cal Point Custom” message will appear. •...
  • Page 18 Notes: • If the reading is not close to the selected value, the WRONG tag will blink. • The meter features the automatic buffer recog- nition function. If the arrow keys are pressed to select the desired calibration value, the automatic buffer recognition function is disabled.

  • Page 19: Temperature Adjustment

    TEMPERATURE ADJUSTMENT The temperature reading can be manually fine-tuned fol- lowing the below procedure. Press SHIFT and CFM keys to enter the temperature adjustment mode. Both primary and secondary LCDs will display the factory default temperature reading. Adjust the temperature reading on the primary LCD using the arrow keys.

  • Page 29: Good Laboratory Practice

    GOOD LABORATORY PRACTICE Good Laboratory Practice (GLP) is a set of functions that allows storage and retrieval of data regarding the status of the system. After a successful calibration, the meter automatically stores the date and time of calibration, and the calibra- tion point(s).
  • Page 30 Standard calibration point(s) Custom calibration point Notes: • To exit GLP mode at any time press SHIFT and GLP. • If the calibration procedure was never performed, the LCD shows the “no CAL” message for a few seconds and then returns to normal measurement mode.

  • Page 31: Log-On-Demand

    LOG-ON-DEMAND To store the current reading into memory, press SHIFT and STORE keys from measure- ment mode. The LCD will display for a few seconds the “Stor” message to- gether with the LOG tag and the sample number. A complete set of information is memorized: date, time, DO and temperature readings.
  • Page 32 The primary LCD displays the date (day and month) and the secondary LCD shows the last stored sample number. If no samples are stored into memory, the “no rEC” indi- cation is displayed. • Select the desired sample number using the arrow keys. If the up arrow key is pressed while the last sample is displayed, the meter returns to the first sample.
  • Page 33 • Temperature reading (only dashes “----” mean reading out of range) • To skip to the next or previous sample, use the up or down arrow keys respectively. For example, if the up arrow key is pressed while a sample reading is displayed, the meter shows the read- ing of next sample.
  • Page 34 • Press SHIFT and CLR to delete the selected record or all records. • If the “dEL All” option was selected, all logged data are deleted and the instrument returns to normal mea- surement mode. • Press SHIFT and MRCL at any time to return to mea- surement mode.

  • Page 35: Hold Function

    HOLD FUNCTION To freeze a stable reading on the LCD, press HOLD key from normal measurement mode. The “Auto” and “H” tags will blink on the LCD until the reading stabilizes. When the reading is stable, the “Auto” and “H” tags stop blinking and the reading is frozen.

  • Page 36: Pc Interface

    To connect your instrument to a PC, use the AD9551 optional Adwa cable. Plug the cable to the instrument RS232 socket and to a serial port of your PC. If not using the AD9551 cable, communication between instrument and PC may be not possible, due to different RS232 connector configuration.
  • Page 37 • dead battery: if batteries become too weak to ensure reliable readings, the meter displays the “dEAd bATT” message for a few seconds and then automatically turns off. Battery replacement must only take place in a safe area and using the battery type specified in this instruction manual.
