Using a Leica TPS1100 Instrument with CDS
 
Introduction
 
Please note that the following instructions refer to operations on the actual Total Station. The staff at Foresight are happy to attempt to answer your questions but you should note that we are not always familiar with the operation of the actual instrument. You may be better referring your question to your local dealer who should know how the instrument actually works! The field operations of the TPS1100 instrument are explained below. Please take time to follow the various steps and understand the process fully.
 
Before you start
 
There are a number of settings that must be standardised on the instrument to make it compatible. Please ensure the following settings are as follows:
 
Recording Mask Settings
Set the REC Mask to the following (Main Menu, 5 - Configure, 1 - Instrument config., 05 - Display and Record, F4 - Rmask.
 
1st word - Point id (11) - Compulsary 7th word - Easting (81) - Optional
2nd word - Hz (21) - Compulsary 8th word - Northing (82) - Optional
3rd word - V (22) - Compulsary 9th word - Elev. (83) - Optional
4th word - Slope Dist (31) - Compulsary
5th word - ppm tot/mm (51) - Compulsary
6th word - Refl. Ht. (87) - Compulsary 
 
Then Press "CONT" to set this recording mask.
 
It is recommended that co-ordinates are also recorded with a measurement. These co-ordinates can then be used for future station setups.
 
Display Mask
Although the display Display Mask and Record Mask are unrelated, The DMASK should contain Reflector Height and Code. 
 
Code List
A valid Code List should be installed on the instrument. This *.CRF file is defined using Leica Survey Office. This can be set on the instrument from Main Menu, 3 - Codelist Management. It can be either on the Internal Memory (C:) or PC Card (A:).
 
Load Coordinates onto Card
You may wish to have a coordinate file loaded onto the memory card for control coordinates. This is optional as you can also enter them into the instrument in the field.
 
Field Survey - Data Collection
 
Getting Started.
 
First set up and level the instrument.
 
From the MAIN MENU, choose F5 (SETUP)
 
Choose the Measurement Job from the Memory Card or select F2 (NEW J) if starting a New Job.
 
Select an existing Data Job (This is the file where coordinates will be chosen from).
 
Check that a codelist has been selected.
 
There are two options now for defining the SETUP. These are F1 (STN) or F4 (QSET).
 
Choose F1 (STN) if you wish to enter the backbearing manually
 
Choose F4 (QSET) to use the Quickset function to automatically orient the instrument from station and backsight coordinates (usually stored on the PC card).
 
Option 1) F1 STN - Setup Station 
 
If you have chosen F1 (STN), you will be prompted for
 
Station Id - Enter the occupied station number.
Inst. Ht. - Enter Height of Instrument (to the dot on the side of the instrument)
Stn. East
Stn. North
Stn. Elev Enter these values or choose F5 to IMPORT the coords from the card.
Hz - Point to the backsight, choose F4 (Set Hz) and key in the backbearing. 
 
F1 (SET) sets the azimuth on the instrument.
 
F3 (REC) Records the Station Information
F1 (CONT) Continues and proceeds to the Measure & Record Screen. 
 
You are now ready to commence the survey. (Go to Measure and Record on next page)
 
Option 2) F4 QSET - Quickset 
 
If you choose Quickset you will be prompted for the Occupied Station ID and the Backsight Point ID.
 
As they are entered, the coordinates will be found on the Memory Card. If the point is not found you have the option of entering the coordinates manually.
 
Enter Inst Ht and Refl. Ht. and point to the Backsight. If a prism is at the Backsight, you can check the distance by pressing F2 (DIST). The Difference in distance is displayed as ? HorizDist. (this should be close to zero).
 
Press F4 (CONT) and then F3 (REC).
 
You will now be at the Measure & Record Screen. 
The next measurement MUST be to the backsight point, just press REC (or ALL to a prism).
 
You are now ready to commence the survey.
 
 
MEASURE AND RECORD.
 
With the cursor on the Point Id line, enter the number of the next point you are about to observe. 
Eg 101 ?
 
Enter the Reflector Height BEFORE any measurements. (or press DIST, change prism height then REC).
 
Take a measurement to the first point by pointing to the prism and touching F1 (ALL). 
This will measure and record the distance and direction to the prism.
 
 
FEATURE CODING
 
Feature codes are entered AFTER the first measurement to a feature. This means that a RECORDED measurement (ALL or DIST/REC) is taken, and then the code is selected. 
 
Choose CODE - you will now see a list of feature codes in alphabetical order.
 
Type the first character of a feature code eg. "C" - The list will now jump to codes beginning with "C" such as CL or Culvert etc.
 
Choose the code required and press Enter
 
You will now be prompted for a String number. Enter a value from 1 to 99 for linear features.
 
Press F1 (REC).
 
The code will stay current until a new code is entered. 
 
Codes can have up to 99 strings each. Eg. 99 Kerbs or 99 CL's etc
 
Code Notes
Similarly, notes can be entered for descriptions to the code. They allow up to 16 characters using GSI16 or 8 characters in GSI8 format.
 
Notes will only appear in the Stadia file for reference purposes.
 
Keeping Track of String and Control Attributes.
There is a new function in V2.03 of the TPS1100 firmware that stores and displays the last user entered attributes for a feature code.
 
To enable this function, set the following (Main Menu, 5 - Configure, 1 - Instrument config., 
06 - Point & Meas. Param, Info/Atrib - Set to "Last User Value"). 
 
This function is very useful for keeping track of string numbers of feature codes. By changing the string number, Cds will draw a separate line for that code.
 
 
LAST CODE - Changing only the String Number or Entering a Control Value.
 
If you are measuring, say a Top of Bank - String 1 and you wish to change coding to a Top of Bank - String 2, press CODE and choose F3 (LAST). 
 
You are able to simply change the string number without the need to call up the feature again.
 
 
QUICK CODING
 
When a code table is defined using Leica Survey Office, a shortcut value is usually assigned to each code. 
 
To access a Feature code very quickly, Point to the prism, choose F4 (Qcod+) and then type the number assigned to the required code.
 
The measurement will be recorded and then you will be prompted for the string value etc.
 
If recording to the same feature, you only now need to press F1 (ALL) for subsequent shots.
 
Changing Reflector Height
 
Remember to change the prism height BEFORE taking a measurement.
 
Lateral Offset using "Split" Measurements
 
When measuring to a tree, a pole or a building etc. You may use a "Split" measurement, by placing the prism offset to the object, pressing F2 (DIST), turning the telescope to the centre of the object and pressing F3 (REC).
 
Entering Offset Values
 
To adjust a measurement by a certain offset value, BEFORE the measurement, choose FNC.4 (Enter Offset Values).
 
You may now enter an offset for Cross (lateral), Length or Elevation. The value can be positive or negative. Lateral offsets are always as viewed from the Station to the Reflector (even in Remote Control mode).
 
The offset will be applied to the next measurement. (Angles and distances will be modified). 
 
Editing and Viewing Recorded Data
 
If you make a mistake, or want to view recorded data, press FNC..5 (Data View and Edit).
 
Press F1 (SEARCH) and the editor will be at the END of the file. You can scroll through the file using the F3 and F4 arrow keys)
 
You may edit certain values only. This is usually manually entered data.
 
For a Code block you may change any value.
For a Measurement block you may only change the Point ID and the reflector height.
For a Station Block you may change Point ID, Reflector Height and Instrument Height.
 
To delete a complete block, navigate to that block, press SHIFT, F5 (DEL). A warning is issued and then choose F4 (YES) or F6 (NO).
 
Processing the survey
 
Data transfer options.
Measurement data is recorded onto the PC Card into the GSI folder. It can be transferred to the PC using either a PC Card Reader or via a Data Transfer cable.
 
1) Transfer using PC Card Reader.
 
Run the Entry...Data Collectors...Import Raw Data in CDS..
 
When asked for the Raw Data File select the drive letter of the PC Card Reader. Eg F:\gsi. (Don't forget the gsi folder!), and then select the job that you wish to process from the PC Card.
 
You have now created a Stadia File which can be reduced with Cds.
 
2) Transfer using Data Transfer Cable.
 
Connect the cable between the instrument and Total Station. Leave instrument turned off.
 
Run Leica Survey Office - make sure the instrument is already registered and the comms settings are set correctly.
 
Choose Data Exchange Manager.
 
The instrument will turn on, GeoCom initialises and data will be read from the PC Card.
 
You will now see a split screen. The instrument files appear on the Left hand side and your computer files appear on the Right hand side.
 
On the LHS - 
Open the Com1: (or Com2) port (by clicking the + Plus sign).
Open the Memory Card folder (by clicking the + Plus sign).
Open the GSI Folder (by clicking the + Plus sign).
 
On the RHS -
Open the drive and folder on the PC where you wish to transfer the RAW measurement data file. (There is also an option to create a new folder by right clicking).
 
Drag and drop the file from the instrument to the data folder.
 
Close Data Exchange Manager and Leica Survey Office. 
 
Run Import Raw Data as in 1) above. Select Raw File from the folder where you downloaded to.
 
You have now created a Stadial File which can be reduced with Cds.
 
Processing Data in CDS
 
 
The Stadia file can now be edited/ reduced with the Electronic Stadia Editor.
 
In Cds go to: ENTRY...ELECTRONIC STADIA....
 
OPEN the file you wish to process.
 
The Editor allows you to check the measurements and correct any errors before processing. 
 
If all is OK choose OPTIONS...STORE DATA IN DATABASE.
 
Close Stadia Editor and do a Zoom Extents to see a graphical view of the job.
 
You can now continue to process your data
