Campbell Scientific GPS16-HVS Garmin GPS Receiver - Manual (Page 19)

Appendix A. CR23X/CR10X Programs
9) HDPFrac, Horizontal Dilution of Precision, tenths
10) Elevation, Elevation in meters
11) Geoidal, Geoidal separation in meters
12) Geoidalth, Geoidal separation in meters, tenths
13) Age, Age of differential GPS data
14) Agetenth, Age of differential GPS data, tenths
15) DiffID, Differential reference station ID
Additional input locations used in the example program are:
18) Orig_TM, Copy of original time
19) Int1, Place holder for math
20) Hours, formatted hours
21) Minutes, formatted minutes
22) Seconds, formatted seconds
23) remainder, place holder for math
Before writing any datalogger code, it’s best to enter all the input locations
needed. In Edlog, open the input location editor (F5) and enter names for the
input locations listed above. When an input location is needed, use the input
location pick list (F6).
