Operational Guide

To view the EC calibration data, press GLP when the instrument is in EC

measurement mode. The instrument will display the calibration standard and

the temperature of the calibrated standard. Use the ARROW keys to scroll

through the calibration data displayed on the 3rd LCD line.
