Re-establishing communications with the device by using ZAGI will turn off the logging.

To plot the data retained in the tiltmeter using ZAGI, you must first download the data to a file on
your PC. Select “
Download Data
” from the “
Memory Options
” menu item and push the “
Start
”
button. ZAGI will then ask you to specify a file name for the downloaded data. If the data file
name chosen already exists, the program will ask whether you want to rename or overwrite the
existing file. After you have made your selection, the program will write the data to your PC.
10.
You are now ready to plot the retrieved data on the X and Y graphs of the ZAGI screen. Click on
“
Plots
” in the command line, and then “
Plot Saved File
.” Then, select the file using the window
that pops up and click “
OK
.” Finally, click on the “
EM
” button or on the “
0
” event marker button
to plot the entire file.
Note:
Event markers are not operational when logging data to the tiltmeter memory.

Data File Format
Data output from the clinometer with a simple string format is a comma-delimited ASCII file with
the following format (assuming simple string format):
X-Tilt, Y-Tilt, Temperature (
C), Serial No., Event Marker
Each line represents one measurement. The time interval between measurements equals the data
output rate of the clinometer:
$0.500,0.458,28.201,N0000,1
$0.500,0.458,28.189,N0000,1
$0.500,0.458,28.189,N0000,1
When data are being acquired and saved to a file only (not logged), the data output interval is not
recorded. It therefore must be remembered by the user for future processing.
When the data are retrieved from the clinometer’s memory (data logging mode), the date, starting
time and output rate are stored in the first line of the output file as shown below:
$start:07-07-1997 10:25:40 4/sec
$0.500,0.458,28.176,N0000,0
$0.500,0.458,28.176,N0000,0
$0.500,0.458,28.174,N0000,0
$0.500,0.458,28.186,N0000,0
$0.500,0.458,28.187,N0000,0
$0.500,0.458,28.189,N0000,0
$0.500,0.458,28.192,N0000,0
$0.500,0.458,28.188,N0000,0
$0.500,0.458,28.189,N0000,0
$0.500,0.458,28.189,N0000,0
The data above represent 10 records collected at a rate of 4 per second for a total elapsed time of
2.5 seconds.
Because event markers are not operational when logging data to the tiltmeter memory, an
event marker of “0” is appended to each line of data.
