Technical Data:
Digital radius gauge (low accuracy)
Measure radius of internal or external arcs
Range of external radius (R1): 5-910mm/0.2-35.83in
Range of internal radius (R2): 7-910mm/0.3-35.83in
Resolution: 0.01mm/0.001in
Accuracy: +/-0.01R
Accuracy formula: R is the radius to be measured; for R=100mm, accuracy is +/-1mm
Buttons: on/off, hold, mm/inch, s (select jaws), zero
Display can be rotated by 320deg
