Example 1: How To Set the Active Channel
To set the active channel to Channel 2 (assuming you have a 274 multiplexer connected),
send the command:
:route:close(@2)
ENTER
Channel 2 will become the active channel and its front panel LED will illuminate.
Example 2: How To Request the Pressure Reading
When using the 670 unit with a single transducer, the response to the report reading command
will report data from Channel 1. If you are using the 670 unit with a 274 multiplexer, the
response to the report reading command will report data from the active channel. Be sure that the
active channel is the channel whose data you want
before
sending the report reading command.
1. To read the pressure on Channel 1, you must first send a command to set the 670
instrument in the pressure reading mode:
:sense:function pressure
ENTER
2. To request the pressure reading, issue the following command:
:measure:function
ENTER
If the transducer is open to the atmosphere and Torr is selected as the pressure units, the
response will be:
measuring 760 <CR LF>
