GPS Reference Manual
38
Interval : is where you enter the interval criteria used for continuous
collection modes. The Interval field is not available if either of the
manual methods is selected.
Update Rate : is where you set the receiver to One Hz or Five Hz mode.
When Five Hz is selected, the receiver will compute positions five
times a second so the display will update in near real time and
measurement latency will be minimized.
6WDUW : opens the Occupy Data Points screen (Page R-39), where data
can be collected.
Offset Shots
6XUYH\ 'DWD &ROOHFWLRQ 2IIVHW 
The Offset Shots screen is used to collect a point you cannot
physically occupy with GPS. You can occupy a nearby point and then
specify an offset to the point stored, or take a shot to it using a laser
range finder.
Offset Point : is the point name of the offset point to be
stored.
Description : is the description of the offset point to be
stored.
$]LPXWK / %HDULQJ : is the direction or bearing from
the occupied point to the offset point.
'LUHFWLRQ IURP 7ZR 3RLQWV : is used to compute the
azimuth or bearing from the reference point to the offset
point by occupying a second reference point on line with
the offset point. Once tapped, a prompt opens for the
name to store the reference point followed by the Occupy
Data Points screen (Page R-39). After measuring the
coordinate at the occupied point, you will return to the
Offset Shots screen where you will be prompted to pick
the direction to the offset point.
=HQLWK / 9HUWLFDO 'LVW : is where you enter the zenith angle or
vertical distance from the occupied point to the offset point.
Slope Dist / Horizontal Dist : is where you enter the slope distance or
horizontal distance from the occupied point to the offset point.
