Ph Calibration Procedures; Auto Cal Using Ph 4.01, 7.00, 10.00 Buffers; Auto Cal Using Other Ph Buffers; Standardize - ECD TC80 Instruction Manual

4.1 H C P
P ALIBRATION
AUTO Calibration recognizes pH 4.01, pH 7.00 and pH 10.00 buffer solutions for automatic, temperature
compensated calibrations. Any calibration solutions can be used but the pH value will have to be entered
manually. Follow the steps below to accomplish a pH calibration. Example uses pH 7.00 and pH 4.01 buffers.
