that appear in the Safety section at the front of the manual. Before you begin, you

Instrument accuracy and display

11.1
One of the benefits of the Nikon DTM-302, NPL-302, and DTM-502 series
products is ease-of-use. The software for these three product series has been
designed to make it easy for you to learn to operate one model of instrument and
apply that knowledge to the other models with little additional training. A
DTM-302 series user can easily operate the non-prism NPL-302 series instruments
or the higher accuracy DTM-502 series instruments.
There are some subtle differences in the software between these different product
families. Some of these differences stem from additional capabilities or features
available in some models. For example, the DTM-502 series offers the Lumi-Guide
functionality, which guides the rodman to the correct stake-out position quickly and
easily. The NPL-302 series offers reflectorless operation, allowing you to take
measurements to points inaccessible with a prism. This manual shows the unique
capabilities and features available in the DTM-302 series instrument.
