16. 1 Introduction 9 2 Calibrating Temperature 9 1 INTRODUCTION The Calibrate Menu allows the user to calibrate the pH ORP or redox and temperature response of the sensor 9 2 CALIBRATING TEMPERATURE 9 2 1 Purpose Temperature affects the measurement of pH in three ways 1 The analyzer uses a temperature dependent factor to convert measured cell voltage to pH Normally a slight inaccuracy in the temperature reading is unimportant unless the pH reading is significantly different from 7 00 Even then the error is small For example at pH 12 and 25 C a 1 C error produces a pH error less than 0 02 During auto calibration the 6081 recognizes the buffer being used and calculates the actual pH of the buffer at the measured temperature Because the pH of most buffers changes only slightly with temperature rea sonable errors in temperature do not produce large errors in the buffer pH For example a 1 C error causes at most an error of 0 03 in the calculated buffer pH The 6081 can be programmed to calculate and display pH at a reference temperature 25 The maximum change in solution pH with temperature is about 0 04 pH C so a 1 C temperature error does introduce small error However the major source of error in solution temperature compensation is using an incorrect tem perature coefficient Temperature affects the measurement of ORP in a complicated fashion that is best determined empirically Without calibration th
