.
Use the up/down arrow keys to scroll thru MIN,
MAX, etc until the desired Sample is displayed. Then press and release the (print icon) key. The display
will flash “Send dAtA” while sending.
Connect and Download Data to a Computer
Use the RS232 computer interface cable (provided) to connect the instrument to a COM port on the
computer. A 9-pin to 25-pin adapter will be required if your computer has a 25-pin serial port connector.
The program “HyperTerminal
®
” which comes with Microsoft Windows
®
can be used for capturing data
sent by the micromanometer. To send data from the micromanometer, use the printing function of the
micromanometer, as shown above.
The program “LogDat™” which comes with your micromanometer can be used to assist in downloading
data to a Windows
®
-based computer and formatting that data. To install LogDat software, run the
SETUP.EXE file on the LogDat distribution disc. Once you open the program, it is self-directing and
provides all
the necessary instructions for downloading data.
Data Acquisition (Polling)
The micromanometer is designed to allow the user to perform polling through the use of a computer. The
computer must send an upper case ‘V’ to the micromanometer while the micromanometer is taking
measurements. The
‘V’
must be sent alone, without a carriage return or linefeed. The micromanometer
will then output the values of the last measurements read. Note that the ‘V’ polling command will not
start the micromanometer taking new measurements, therefore, it works much better if the
micromanometer display mode is set to
RUNAVG.
You must write your own program to use the ‘V’ polling command. Therefore this command is only
designed for medium-to-advanced programmers who need real-time data acquisition. The ‘V’ polling
command cannot be used to request logged data.
