11 SETTING THE PRISM / NON-PRISM CONSTANT VALUE
The prism constant value of Topcon is set to zero. When using prisms other than Topcon’s, it is
necessary to set the prism constant correction value of that specific prism.
Once you set the correction value for prism constant, it is retained after power is OFF.
Note: Confirm the non-prism constant value is set at 0 when measuring target such as walls in
Non-prism mode.
