• Measuring faces: Carbide.
Hold:
Pressing the HOLD button freezes the current value in the
display. This function is useful for preserving a measurement
in situations of poor visibility when the instrument must be
moved away from the workpiece before the reading can be
recorded.
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.
Auto power ON/OFF:
The reading on the LCD disappears after this instrument is
idle for approx. 20 minutes, but the origin point is retained.
• Dust-tight and water Turning the spindle causes the reading on the LCD to
jet protected IP65 reappear.
Data output:

(SPC) system.
Error alarm:
In the unlikely event of a display overflow or calculation
293-180 error, an error message is displayed and measurement stops.
Measurement cannot continue until the error is corrected.
Also, if the battery voltage drops below a certain point, the
battery indicator will turn on before measurement becomes
impossible, warning the user that the battery needs to be
replaced.
