  • Page 24: Operational Guide

    BASIC VS STANDARD pH MODE The “Standard” pH operation includes up to a 5‑point buffer calibration, use of custom buffers, choice of displaying 0.001 pH resolution, use of the full diagnostic features of Calibration Check™ (that includes buffers used, probe condition, response time and messages indicating a contaminated buffer or pH sensor requiring maintenance during calibration).

  • Page 25: Ph Meter Configurations

    pH METER CONFIGURATIONS edge’s pH meter operation is configured by using the SETUP/CLR key with a pH probe connected to the meter. The parameter‑specific options will be seen inserted into the menu. If Basic mode is “On”, the pH parameter list will not be displayed. See Basic mode for a description of this operation before choosing how to SETUP the meter.

  • Page 26: Ph Calibration

    pH CALIBRATION Calibration in Standard Mode pH operation in standard mode offers full function of edge . This includes seven standard buffers ® pH and two custom ones. Five pH buffers may be used for calibration. The instrument should be recalibrated whenever: •...
  • Page 27 The custom buffers allow the user to calibrate in a buffer solution different from a standard one. Two custom buffers can be set in SETUP menu. See page 28 for more information about using custom buffers. The instrument will automatically skip custom buffers which are in a ±0.2 pH window of an already calibrated buffer.
  • Page 28 When the reading is stable and close to the selected buffer, “CFM” tag will blink. Press GLP/CFM key to confirm calibration. Repeat procedure with additional pH buffers. A total of five pH buffers can be utilized. After confirming the last desired buffer calibration points, press CAL/MODIFY key (or if all five buffer values were calibrated) the instrument will automatically display “SAVING”...
  • Page 29 First Calibration Point When performing a new calibration, or adding to an existing one, the user has a choice of how the first new calibration point will be treated in reference to the existing calibration point. This is selected in SETUP by the option FIRST CALIBRATION POINT. The two SETUP selectable options are “POINT” or “OFFSET”.
  • Page 30 If the instrument is not calibrated the calibration history has been deleted, or it has been calibrated only at one point, the electrode condition and the electrode response gauges will be empty. For a continuous display of the electrode’s condition and response, daily calibration is necessary. This information can also be viewed in the GLP data.
  • Page 31 The “ ” along with “STIR” tag will be displayed and “WAIT” will blink on the LCD until the reading is stable. When the reading is stable and close to the selected buffer, the “CFM” tag will blink. Press GLP/CFM key to confirm calibration. After confirming the first calibration point, the calibrated value will be displayed on the first LCD line and the second expected buffer value on the third LCD line.

  • Page 32: Calibration Messages

    If the value measured by the instrument is not close to the selected buffer, “WRONG BUFFER” will blink. Check if the correct buffer has been used, or clean the electrode by following the Cleaning Procedure. If necessary, change the buffer or the electrode. If the buffer temperature exceeds the temperature limits of the buffer, “WRONG BUFFER TEMPERATURE”...
  • Page 33 Wrong Buffer This message appears when the difference between the pH reading and the value of the selected buffer is too great. If this error message is displayed, check if you have selected the proper calibration buffer and have poured the desired buffer. Wrong Old Points Inconsistency “WRONG OLD POINTS INCONSISTENCY”...

  • Page 34: Ph Glp Information

    Bad Electrode “BAD ELECTRODE” appears if the cleaning procedure performed as a result of the above two messages is found to be unsuccessful. In this case it is advised to replace the electrode. Wrong Buffer Temperature “WRONG BUFFER TEMPERATURE” appears if the temperature of the buffer is outside the defined buffer temperature range.
  • Page 35 If calibration has not been performed, the instrument displays a blinking “NO CAL” message. After the calibration has been performed the instrument displays offset and slope. The GLP slope is the average of the calibration slopes; the percentage is referenced to the ideal slope value at 25 ºC. Additionally the condition and response indicators displayed are from the last calibration.

  • Page 36: Ph Measurement

    If a buffer is not from the last calibration, the buffer tag will be displayed blinking. In Standard Mode, Condition and Response gauges are visible on the day of calibration (See Electrode Condition And Electrode Response Time page 29). If configured in SETUP, a countdown message displays the number of days remaining until a new Calibration is due.

  • Page 37: Relative Mv Calibration

    Error Messages During Measurement If the pH or temperature exceeds the limits of the sensor, the message “ELECTRODE OUT OF SPEC” will scroll on the third LCD line. The temperature will continue to be displayed. If temperature exceeds the meter specification of 120 ºC, then “120 ºC” will blink on the display. If interval logging, the message “OUT OF SPEC.”...
  • Page 38 Submerse the ORP electrode approximately 3 cm (1¼”) into the solution and stir gently. Press CAL/MODIFY key when the instrument is in RELATIVE mV measurement mode. The “CAL” tag will appear and the Absolute mV is displayed on the primary LCD line and “AbS” message on the secondary LCD line.

  • Page 39: Relative Mv Glp Information

    Press GLP/CFM key to confirm the relative mV value. The display will show “SAVING“ and returns to measurement mode. Note: The relative mV value can be changed only inside the relative mV offset window (± 2000 mV). RELATIVE mV GLP INFORMATION Good Laboratory Practice (GLP) refers to a quality control function used to ensure uniformity of sensor calibrations and measurements.

    If disabled, “EXPIRATION WARNING DISABLED” is displayed. Or if enabled the number of days until the calibration alarm “CAL DUE” will be displayed. (i.e. “CAL EXPIRES IN 2 DAYS”) The number of days since the calibration expired. (i.e. “CAL EXPIRED 2 DAYS AGO”).
  • Page 41 The Relative mV value is displayed on the first LCD line and the temperature on the second LCD line. Using the keys, date, time, battery status and offset can be displayed on the third LCD line. If the reading is out of measurement range, the closest full scale value will be displayed blinking on the first LCD line.

    ORP PROBE MAINTENANCE Remove the protective cap off the ORP electrode. Wash off any SALT DEPOSITS. This generally confirms the reference junction is free flowing. If the storage cap is dry, the reference junction may be dry also. Soak the electrode in HI70300 HI80300 storage solution for at least one hour.
  • Page 46 Storage Procedure To minimize clogging and ensure a quick response time, protect the ORP sensor by using the storage cap. Add a few drops of HI70300 storage solution to the cap to keep the reference junction wetted. Periodic Maintenance Inspect the sensor and cable. The cable used for connection to the edge must be intact and with no points of broken insulation.
