Units of Measure
The AccuMap 12 can show its data in many differ- ent formats. For example, distance can be dis- played in statute miles (MI), nautical miles (NM), or kilometers (KM).
The following can be changed on the Units of Mea- sure menu: (Defaults shown in bold)
Distance | miles, nautical miles, kilometers |
Speed | miles per hour, knots, kilometers per hour |
Bearing | magnetic, true |
Altitude | feet, meters |
Clock |
|
Position Format | degrees, minutes, and thousands of a minute |
| degrees, minutes, seconds |
| UTM |
To change a unit of measure, first select the “Units of Measure” from the “System Setup” menu. The screen shown at right appears. To change a set- ting on this menu, highlight the desired selection, then press the left or right arrow key. You can change one or all of the settings on this page.When you’re finished, press the EXIT key.
Position Format
The AccuMap 12 can show the position in degrees, minutes, and hun- dredths of a minute (36 28.700') or degrees, minutes, and seconds (36 28' 40.9". It can also show position in UTM’s or Universal Transverse Mer- cator projection.
UTM’s are marked on USGS topographic charts. This system divides the Earth into 60 zones, each approximately 6 degrees wide in longitude. Their unit of measure is in meters. For example, 15 N means that the position shown to the right of the “N” is in grid 15, and it’s north of the equator.
To change the position format, move the black box to the “Position Format” label on the Units of Mea-
sure menu, then press the right arrow key. A screen similar to the one below appears.
