Get started with the CM3 series (quick start). Quick starts with a fixed solution using the CM-Survey software to set up the external station 1-N mode. The previous instrument installation is detailed in Chapter 3 Receiver Field Work Requirements. 1.1 Connecting the instrument The CM3 series uses WiFi or Bluetooth to connect instruments.
if the residuals are small, indicating that the correction is qualified, click on "Application" and select "Yes" in the pop-up prompt. Note: (1) Known points are best distributed at the edges of the entire job area, for example, if point correction is done with four points, the measuring job area is best inside the quads connected to the four points.

Slope Height Vertical Height Control Points Step3Record Record the name call, instrument SNnumber, instrument height, start observation time. Step4Collect static data Turn on the receiver, set the receiver to static mode, the receiver will automatically start recording static after searching for enough satellites; Receiver records static process do not touch scaffolding or instruments, try to avoid human interference, arrange for special guards.
After the whole point storage --- select the whole point, the recording duration needs to be set to a value that can be divisive by 1440 minutes The loop storage --- automatically overwrites the thread's early data after the set storage space has been exceeded After a single acquisition --- select Yes, that is, after recording a file with a set duration, stop, or not as a continuous record Storage locations --- optional internal and external storage, which is external storage Storage space --- reserves memo
Note: Web mode focuses on settings, you can set how many sets of data are logged on and off, and ftpmode focuses on data export, so data export is recommended using ftp mode or Type-C data line export. 5.4 Static accuracy test Static measurement accuracy refers to the degree to which the static measurement baseline vector results of the device under test conform to the known baseline vector (horizontal and vertical components). Static measurements are tested on outdoor reference points.
