Page 14: Automatic Calibration Procedure
This PE-8E is capable for automatic and manual calibrations. ③ It is changeable by DIP Switches. Refer to the page: During calibrations by standard solutions, control actions ALM 1 , ALM 2 are all OFF. ④ During calibrations by standard solutions, transmission output turns into the mode set by DIP ⑤... - Page 15 Push CAL key. ③ Stability of electrode potential is discriminated, then calibrates it to the pH value of standard solution at that temperature of discrimination. MEAS DISP Push CAL key again even if you calibrate with the same standard solutions. It is possible to calibrate many times with the same standard solutions, but the only final data is effective.
