Preparation 3
To maintain the accuracy of your measurements:
• When measuring a short distance, incline the prism slightly so that the EDM
can ignore unnecessary reflections on the prism surface, as shown below.
B
Tip – Hold the prism securely in place and do not move while taking measurements.
In Prism mode, in order to avoid false measurements on objects other than the prism or
reflector-sheet, targets that are less reflective than the prism or reflector sheet are not
measured. Even if you start a measurement, measured values are not displayed. To
measure less reflective objects, use the N-prism (reflectorless) mode.
