Functions

Origin point setting (ABS measurement system): Resets the ABS origin at the current spindle position to the minimum value of the measuring range and switches to ABS mode.
Zero-setting: A brief press on the ZERO/ABS button sets display to zero at the current spindle position and switches to the incremental (INC) measuring mode. A longer press reset to the ABS measuring mode.
Hold: The function that holds the display of value is useful when it is difficult to see the measured value at the measurement point. When the function is cancelled. the previous zero-set point or a measured value with reference to the origin is displayed.
Data output: Models equipped with this function have an output por for transferring measurement data to a Statistical Process
Control (SPC) system.
* Only models with the data output function
Auto power ON/OFF : The reading on the LCD disappears after this instrument is idle for about 20 minutes, but the reading and measurement mode are retained. Turning the spindle causes the reading to reappear.
Error display: In case of an overflow on the LCD or a computing error, an error message appears on the LCD, and the measuing function stops. This prevents an instrument from givinge erroneous reading. Also, when the battery voltage drops to a certain level, the low-battery-voltage alarm indicator appears well before the micrometer becomes unusable
Function lock: This function allows the ORIGIN (origin point setting) function and the ZERO (zero-setting) function to be locked to prevent these points being reset accidentally.
