Accuracy is a metric of how close a given measurement is to the displayed measurement (when compared to a given tape measure). Precision is how close multiple pieces are relative to one another at the same measurement. Both are achievable using the M1 Caliber following best practices outlined for standard M1 use.

Resolution is the smallest value that can be read for the M1 Caliber. For the M1 tool, this value is close to 0.040mm but the actual displayed resolution varies by measuring units (see units for additional information).

Hello, The resolution of 0.040 is great but can I acheived a precison of + or - 0.5mm with this tool if freshly calibrated on site?
Hello Claude, under perfect conditions, yes (and its precision in ideal conditions will hit that) but based on practical elements may vary more than that being an open loop system (wheel measuring sliding piece of material).
Good thanks Derrick, can you define "perfect conditions" for me? Thanks
Hi Claude, some factors include: 1) calibration has been performed each day 2) same temperature 3) Mounted securely 4) measuring same material type and surface geometry 5) proper use and consistenly sliding material
Hello Derrick, thanks much for the response. All points makes perfect sense.
