When using the Nikon gun in metric mode, you may see distances which are off by a factor of 10. To verify this, go into the Stake program, switch to the RAW screen, and take a shot with the instrument. Verify the information on the 48 display against the information on the instrument display.

Nikon Topgun series instruments transfer the slope distance without a decimal point in the data. For example, a distance of 321.88 feet is transferred to the HP48 as "321880" and the HP must convert this to the correct distance. Unfortunately, when configured for metric, some models require that the implied decimal point be inserted in a different position.

If you encounter this problem with your instrument, you can install this additional total station driver to correct the problem.

Use the following procedure to load the driver (similar to loading advanced programs):

• We recommend copying the files on your Party Chief floppy to a folder on your hard disk to perform this procedure.
• Download and save ntopgunm.tsd to the folder where you copied the Party Chief disk. When you click on the link above to download the file, if your browser displays the text rather than prompting you for a file name, try right clicking the link above and select "Save Target As" (IExplorer) or "Save Link As" (Netscape), or something similar from the popup menu.
• Change to the folder where you have copied the files and run AUTOLOAD or insert the floppy disk in your computer and type A: [Enter] AUTOLOAD [Enter]
• Answer the COM port prompt to use the correct port.
• On the HP48 go to Config program.
• Select Automatic Input (Option 0).
• Select OTHER for the method (Option 1).
• At the prompt for driver name enter NTOPGUNM.TSD (If you have an older version of Party chief and it does not prompt you to load a driver, see the Loading Other TS Drivers TechNote)
• Follow the instructions on screen and press LOAD softkey.

Select the Other driver in Config to work on metric projects. Use the regular Nikon driver when the instrument is configured for feet.
