Page 11: Operational Guide
OPERATIONAL GUIDE POWER CONNECTION Plug the 12 VDC adapter into the power supply socket. Notes: • These instruments use non volatile memory to retain the pH, mV, Ion, temperature calibrations and all other settings, even when unplugged. • Make sure a fuse protects the main line. ELECTRODE AND PROBE CONNECTIONS For HANNA P type pH or ORP electrodes (with internal reference) connect the electrode’s BNC to the socket on the back of the instrument (#8 on page 4... - Page 12 • The instrument automatically defaults to pH or mV measurement mode, if a HANNA P type pH or ORP electrode is detected. • If no HANNA P type electrode is detected, the instrument starts in the same range as it was at power off. pH MEASUREMENTS Make sure the instrument has been calibrated before taking pH measurements.
- Page 13 The temperature can be adjusted with the ARROW keys or the numerical keypad (from –20.0 ºC to 120.0 ºC or from –4.0 ºF to 248.0 ºF). Press NUM to change the temperature value with the numerical keys. The “2nd” tag will blink. Press CLR or 2nd then CLR if you want to delete digits of the displayed value.

Page 14: Temperature Measurements
Note: Press from the left keypad to toggle between temperature and absolute mV reading on the secondary LCD. The Relative mV reading is equal to the difference between the absolute mV input value and relative mV offset established in the relative mV calibration. -
Page 15: Ph Calibration
pH CALIBRATION Calibrate the instrument often, especially if high accuracy is required. The instrument should be recalibrated: • Whenever the pH electrode is replaced. • At least once a week. • After testing aggressive chemicals. • If “CAL DUE” tags are blinking during measurement. •... - Page 16 All new calibrations will override existing stored calibration data, in a ±0.2 pH window, at these calibration points. The slopes adjacent to the calibration points will be reevaluated. If the new calibration point has no correspondence in the existing stored calibration data, it is added to it if this is not full, or the instrument will ask which buffer will be replaced by the current buffer.
- Page 17 • The “ ” tag will blink on the LCD until the reading is stable. • When the reading is stable and close to the selected buffer, “CFM” tag blinks. • Press CFM to confirm calibration. • The calibrated value is then displayed on the primary LCD and the secondary LCD will display the second expected buffer value, together with “CAL”, “Cal Point 2”...
- Page 18 • After the third calibration point is confirmed, immerse the pH electrode and the temperature probe approximately 4 cm (1½”) into the fourth buffer solution and stir gently. The temperature probe should be close to the pH electrode. • If necessary, press the ARROW keys to select a different buffer value. •...
- Page 19 If the existing stored calibration is full (five calibration points), the instrument asks which buffer will be replaced by current buffer. Press the ARROW keys to select another buffer to be replaced. Press CFM to confirm the buffer that will be replaced. Press CAL to leave calibration without replacing.

Page 20: Enhanced Calibration Messages
ENHANCED CALIBRATION MESSAGES The stored calibration history to used issue error and warning messages during calibration to help ensure the highest accuracy. As electrode aging is normally a slow process, substantial changes from previous calibrations are likely due to a temporary problem with the electrode or buffers. -
Page 21: Electrode Condition & Electrode Response Time
CLEAN ELECTRODE This warning message appears in order to alert the user that some dirt or deposits could be on the electrode. Refer to the electrode Cleaning Procedure. This ensures the removal of film, dirt or deposits on the glass bulb and reference junction. -
Page 22: Relative Mv Calibration
The electrode response is evaluated only when calibration has been performed using pH 7.01 or pH 6.86, pH 4.01 and pH 10.01 or pH 9.18 buffers. When the instrument cannot evaluate the electrode response or pH 1.68/12.45 buffer was used as calibration buffer, the response gauge will be empty. -
Page 23: Ise Calibration
ISE CALIBRATION For greatest accuracy, it is recommended to calibrate the instrument frequently. Due to electrode conditioning time, the electrode must be kept immersed a few seconds to stabilize. The user will be guided step by step during calibration with easy to follow tags on the display. This will make the calibration a simple and error-free procedure. - Page 24 • The calibrated value will be displayed on the primary LCD and the second expected standard solution on the secondary LCD. Note: The instrument will automatically skip the standard used for the first point. • After the first calibration point is confirmed, immerse the ISE electrode approximately 4 cm (1½”) into the second standard solution.

Page 25: Good Laboratory Practice (Glp)
GOOD LABORATORY PRACTICE (GLP) GLP is a set of functions that allows storage and retrival of data regarding the maintenance and status of the electrode. All data regarding pH, Rel mV and ISE calibration is stored for the user to review when necessary. CALIBRATION ALARM TIME OUT For pH calibration, all the instruments allow the user to set the number of days before the next required pH calibration. - Page 26 • The pH calibration offset. • The pH calibration slope (the GLP slope is the average of the calibration slopes; the percentage is referred to the ideal value of 59.16 mV/pH). • The calibration buffers in calibrating order, with the corresponding warnings.
- Page 27 The fourth pH calibration buffer: The fifth pH calibration buffer: Notes: • The “OLd” message displayed beside the pH value means that this buffer was not used during last calibration. Press 2nd then SET key if you want to see calibration date (or time, if old calibration was performed in the same day with current calibration).
- Page 28 LAST ISE CALIBRATION DATA Last ISE calibration data is stored automatically after a successful calibration. To view the ISE calibration data, press 2nd then GLP key while in ISE measurement mode. The instrument will display the date (yyyy.mm.dd) of the last calibration as in pH GLP mode.
- Page 29 LAST RELATIVE mV CALIBRATION DATA Last Relative mV calibration data is stored automatically after a successful calibration. To view the Relative mV calibration data, press 2nd then GLP key or simply GLP from the left keyboard (HI 121) while in Relative mV measurement mode. The instrument will display the Relative mV GLP information.

Page 55: Temperature Correlation For Ph Sensitive Glass
TEMPERATURE CORRELATION FOR pH SENSITIVE GLASS The resistance of glass electrodes partially depends on the temperature. The lower the temperature, the higher the resistance. It takes more time for the reading to stabilize if the resistance is higher. In addition, the response time will suffer to a greater degree at temperatures below 25 ºC (77 ºF). -
