Calibrating Measurements
‹ This function is used to calibrate the deviation which is occurred between the displayed-
measurement of the product and the reading of calibrated vacuum gage you have （e.g.
manometer ）.The calibrated informations relate to the ramp control mode.
‹ It is programmed in the function menu of the fixed value control mode and of the free mode.
The calibration mode is accepted either before or during operations.
The following shows the procedure for calibrating while the fixed value control operates.
