The Absolute MyCal E-Z Digital Caliper allows direct measurements from power on. You can forget the time consuming origin setup which otherwise is required each time the power is turned on. Zero-setting of the display is also possible at any slider position for easy comparison measurements (incremental mode). Large .295 inches high LCD digits (.365 inches high LCD digits for 12 inch Model) allow measurement results to be at a glance. A scale contamination detection function is implemented to detect contamination of surface and display the error message (ErrC) on the LCD. The correct value is only displayed if the contamination is removed. The battery life has been greatly extended with the power-conserving design permitting 3.5 years (20,000 hours) continuous operation with a single battery.
