254 SETUP…Sensor A: Buffer Method (pH probes only)Select the type of manual calibration required:Man 1-Pt – Manual, single-point calibrationMan 2-Pt – Manual, two-point calibrationSet Buffer TemperatureDeg.C (or Deg.F) and Adjust are shown alternately on the center display line. Use theand keys to adjust the displayed temperature value to the required buffer temperature(–20 to150C or –4 to 302F).Note. If A: Buffer Method is set to Man 2-Pt, the temperature selected is used for bothbuffers.Calibrate Buffer (Single-Point Calibration) or Calibrate Buffer 1 (Two-Point Calibration)Immerse Sensor A in the buffer solution.pH and Adjust are shown alternately on the upper display line. Use the and keysto set the displayed pH value to the temperature-corrected pH value of the chosen solution(see the datasheet provided with the solution).Press the key to initiate calibration.Note. To abort calibration, press the key again at any time before calibration iscomplete – see below.Measured pH value from the last successful calibration.Measured sensor output in milivolts.When the measured sensor output stabilizes, press the key to accept the calibration.Cal. Accepted is shown for 2 seconds to confirm that the calibration has been accepted,the display then advances automatically to the next frame.The display then changes for 2 seconds to show the temperature-corrected buffer value inthe upper display line, then advances automatically to the next frame.Two-point calibration selected – continued on next page.Single-point calibration selected – continued on next page.Abort CalibrationSelect Yes or No.Yes selected – return to the main menu.No selected – calibration continues.4.01175mVA: Immerse Buf.2A: CalibrationA: Abort Cal.-----YesA: SENSOR CAL.A: Immerse Buf.2A: Immerse Buf.14.00pHDeg.C25.0A: Buffer MethodMan-----1-PtA: Cal.
