[. . . ] Press the ARROW keys to change the displayed value. Press the CFM key to save the modified value or press the CAL key to cancel without saving the date. 22 CURRENT YEAR SET Press the CAL key when the current year is displayed. The year will begin blinking. Press the ARROW keys to change the year. Press the CFM key to save the modified value or press the CAL key to cancel without saving the year. BEEP STATUS SET Press the CAL key when the beep status is displayed. The beep status (On or OFF) will begin to blink. Press the ARROW keys to change the beep status (On or OFF). Press the CFM key to save the modified beep status or press the CAL key to cancel without saving the beep status. Note: If enabled, an audible signal will follow each key press. A longer beep is also sounded when the limits of the range of a parameter are reached. An audible signal will also sound when the reading becomes stable during calibration. 23 SERIAL COMMUNICATION BAUD RATE SET Press the CAL key when the baud rate is displayed. The baud rate (600, 1200, 2400, 4800 or 9600) will begin to blink. Press the ARROW keys to change the baud rate. Press the CFM key to save the modified baud rate or press the CAL key to cancel without saving the baud rate. SERIAL COMMUNICATION COMMAND PREFIX SET Press the CAL key when the command prefix is displayed. The command prefix (0 to 47) will begin to blink. Press the ARROW keys to change the command prefix. Press the CFM key to save the modified command prefix value or press the CAL key to cancel without saving the command prefix. Note: See the PC Interface section on page 28 for a complete explanation. The command prefix must be 16 if the HI 92000 PC software is used. 24 TEMPERATURE CALIBRATION (for technical personnel only) The instruments are factory calibrated for temperature. Hanna's temperature probes are interchangeable and temperature calibration is not necessary when replaced. If the temperature measurements are not accurate, temperature recalibration should be performed. For an accurate recalibration, contact your dealer or the nearest Hanna Customer Service Center, or follow the instructions below. · Prepare a vessel containing ice and water and another one containing hot water (around 50 °C). Place insulation material around the vessels to minimize temperature changes during calibration. · Use a ChecktempC or a calibrated thermometer with a resolution of 0. 1 °C as a reference thermometer.
