(This functionality is available with the Input / Output module)
This topic documents the field operations for a TC-600 with firmware version 1.x. If your TC-600 has firmware version 2.x, refer to the TC-600 V2 topic.
Two recording Formats are available in the TC-600.
Mask 1: Point Number, Horizontal circle, Vertical Circle, Slope Distance, ppm/mm, Height of Instrument,
Height of Target.
Mask 2:Point Number, Horizontal circle, Vertical Circle, Slope Distance, East Co-ord, North Co-ord,
Elevation, Height of Target.
It is recommended that Mask 1 be used.
Since Mask 2 has no specific information word for Instrument Height, the Height of Target word is interpreted by the system as an instrument height for station setups. (See below for details of instrument setup)
Note:
- The system uses point identifiers and the point identifier is extracted from the measurement block.
- For metric data files, all distances are assumed to be in millimetres or tenths of a millimetre (as set on the instrument) unless a decimal point is encountered.
- For imperial data files, all distances are assumed to be in tenths or hundredths of a foot (as set on the instrument) unless a decimal point is encountered.
When using the TC-600, feature coding is entered as part of the eight character point identifier. The TC-600 does not use the standard Leica/Wild operation codes.
The feature code and string combination can be set to varying numbers of digits as specified in the Settings/Code Definition command.
Using the TC-600 keyboard to edit the point identifier field.
(That is, to change the feature code, string identifier, or point identifier)
| Item | Used to |
| Menu: | Access the menu options |
| Set PtNr: | To select the feature code / string characters / point id display |
| Cont: | Access the Set PtNr display |
| All: | Decrease the underlined digit |
| Dist: | Increase the underlined digit |
| Rec: | Move the cursor to the right one character per time |
| Cont: | Accept the entered point id field and move the cursor to the hr (height of reflector) field |
| Cont: | Accept the hr input and return to the measurement display |
Examples of feature coding options
| System Code definition | Example | Explanation |
| CCCSS | 10201999 | Feature code 102; string id 01; point id 999 |
| CCCS | 10219999 | Feature code 102; string id 1; point id 9999 |
| CCC | 10299999 | Feature code 102; string id not used; point id 99999 |
Note that you must use the same code structure for the whole of any particular job.
Examples of Station Setup options
A station setup is identified by recording a measurement block with no distance. When this occurs, the point identifier field is interpreted as the first four digits being the RO point identifier, and the last four digits as the setup station identifier. Refer to the following examples.
| Point ID Field | Explanation |
| 00000100 | The instrument is set up at point 100 and there is no RO. That is, the following observations will be assumed to be on datum. |
| 01000200 | The instrument is set up at point 200 and the RO is point 100. |
After setting the point identifier field for a new setup and returning to the measurement display, press REC to record a measurement block with no distance. The block will then be interpreted by the system as a new setup.
NOTE: For Mask 2, the target height word is used by the system as the instrument height. Therefore, when setting up using mask 2, ensure that the zero distance observation has the target height word as the instrument height.
