The order of the entered figures is:
Date: „two last figures of year + XXXX(date)‟
Time: „XX(hour)+ XX(minute) + XX(second)‟
Press „Enter‟ to save.
Notice: a „0‟ to occupy a place for month or days with single
figures is required. e.g Second the March= 0203
9.7 Grid Factor
Formula:
1) Altitude factor= R / (R+Altitude)
R:the earth's average curvature radius
Altitude: Altitude above the mean sea level
2) Scale factor:the measurement station scale factor
3) Grid scale factor :Altitude factor × Scale factor
grid distance:
1)Grid scale distance(HDg)= HD×Grid scale factor
HD= distance on the ground
2) Distance on the ground(HD)= HDg/Grid scale factor
Input altitude in the „Altitude‟ column and press soft key
„Enter‟ to calculate the Grid scale factor as shown in the picture
above. Press „ENT‟ to save the Grid scale and end the dialogue
box. A box saying „Saved‟ will flash once.
When the calculated grid factor is less than 0.99 or greater
than 1.01 ,it indicates that one of the input between altitude and
scale is wrong, the system cannot receive the grid scale at this
moment, so you must input again. Use "ESC " button to exit
without saving.
9.8 USART option
RS232C means that when two-way communication, the
system will export and import through the RS232C port.
Bluetooth means that when two-way communication, the
system will export and import through Bluetooth device .
9.9 Selecting disc
FLASH means that the working files and coordinate files
will be saved into the internal storage.
SD means that the working files and coordinate files will be
saved into the SD card
.
