BEVA CM84 Handheld GPS Glonass Beidou Length And Land Area Measure
Calculation Meter
Welcome to use the GPS area measurer. This product is high performance, simple operation and a functional instrument. To make sure you can get right accurate measuring result, please read this carefully before using this product. We believe it will become your work right-hand man in area measurement when you master it. Please be sure to use the power adapter for this device to the master charging machine. The picture in the manual is only for reference.
The key introduction
There are totally 9 function keys, they are
- Area measurement, there are two kinds of measurement methods：auto track measurement, and collected points measurement.
- Length measurement, there are two kinds ofmeasurement methods: auto track measurement, and 2 points distance measurement
- Long press the power on/off.
- Return to previous menu.
- Move the cursor up or implement plus function.
- Move the cursor down or implement reduce function.
- To start or end measurement or complete setting.
- etting for unit price, slope, unit of area and unit oflength, LCD brightness and time UTC.
- Review the measured records.
Introduce the content of screen
After power on the main interface as below(there are slight differences based on the status of device setting)
The symbols in different interface represents the meaning described below:
- GLONASS positioning condition: Zero lattice signal representation is not positioned,1~5 lattices is represented separately poor, medium, excellent quality of positioning. In order to ensure the accuracy of measuring results,we strongly recommend that you start to measure after the signal reach 3.
- GPS positioning condition: Zero lattice signal representation is not positioned,1~5 lattices is represented separately poor, medium, excellent quality of positioning . In order to ensure the accuracy of measuring results,we strongly recommend that you start to measure after the signal reach 3.
- Positioning accuracy: represent the current level of precision
- Time: represent local time
- Battery status: represent current battery status, the more the grid cells is, the more power is.
- Longitude & latitude: represent current longitude and latitude.
- GLONASSsignalintensity.
- GPS signal intensity.
Basic setting
At the main memu, press the key
Under this menu, press the key or select the setting you need then press the key。 When the selection flashing， press the or key can adjust the figures。 Press the or key without release, can adjust figures quickly。
Afterset the figure you need， press the key to the home menu, the figure is already saved.
- Price setting: It has the function of calculating price according to the measurement of land area。 First, you set the price for unit area, then the total price is equal to the unit price multiply the land area.
- Slope setting: Set the correct slope values can increase the accuracy of measurement. The slop value is 0 when there is no slop.
- Area uint setting: Theunitcanbesquarefeet, square meters, acres&HA.
- Length unit setting: Theunitcanbesetfeet, meters, kilometers &mi
- LCD Brightness setting: You can set the screen brightness on the settings interface. You can also press the up / down button when you need to adjust the screen brightness in the measurement. Becausethebrighter the screen is, the more energy consumption,we suggest taking the brightness you can see clearly the standard in order to extend the battery life.Current time =Greenwich time+ time zoneoffset time.Suchas the timeof Eastern United States is 4 hours less than Greenwich time, so the time need to be set to:-4：00.
All selected function settings are finished, press the key to the home menu.
Auto-track area measurement Firstly： press the key , to choose the measurement method you need, and set the unit price 、area unit 、Length unit and slope.
Secondly, ensure the device is in a good state of satellite positioning, press the key to start measurement.It will displays the current area in real-time at the bottom of the screen, as shown in the following figure:
Thirdly, take the GPS area measurer and walk around the targeted land, a circle around the area to be measured,then press the key to end of area measurement, the result of measurement is displayed onscreen, pressthe key to view current results and final path graphics, as shown in the following figure.
Note: when in a non-linear measuring, the speed is best not too fast or not too slow(normal walking speed),it can improve the accuracy of measurement, But in a straight line segment from impact speed.
Collected points area measurement: Firstly：press the key to choose the measurement of the collected point, and set the unit price 、area 、and slope.
Secondly, ensure the device is in good state of satellite positioning, press the key to start collected points measurement, Itwilldisplaysthe current area and lengthen real-time at the bottom of the screen, as shown in the following figure: Thirdly, press the key to add a point, the bottom f screen displays the current area and length, as shown in the following figure.
Fourth, step over operations, until all the joints are complete, press the key
to end display the measurement result. Thenpressthekey between graphic and
track the results, as shown in the following figure:
If fewer than three points, it will remind too few points to constitute an area of computing, you need to continue sampling. Appearasbelow:

Secondly, press the key , and walk around the block, the system will display the distanceinr ealtime, as shown in following:
Thirdly, press the key toendthe length measurement, the measured result will bes hown as below:
2pointsmeasurement, Ifyouwanttomeasurethestraight-linedistancebetween2points, you can take this measurement method to measure the distance. Press the key to choose the length measurement method Firstly, as shown in following:
Secondly, press the key to add point, the bottom of screen displays the current distance. Thirdly, press the key to end and display th measure meant result.as shown in following
