Test Measurements - Teledyne 300 Instruction Manual

7.5 Test measurements

All the test measurements which can be displayed by pressing the TEST button are also
available to the host computer via the RS-232 interface. The host computer should issue
a request for a test measurement, and then the CPU will send the current value of the test
measurement to the RS-232 output. The format of the test measurement message is:
"T DDD:HH:MM IIII TEST MEASUREMENT<CRLF>"
For example, the format of the DC Power Supply output in millivolts would be:
"T 194:11:29 0000 DCPS= 2500 MV<CRLF>"
To request a test measurement, the host must issue a command of the form:
For a summary of all test functions issue the command "T LIST". The table below lists
the commands and the corresponding test measurements which will be returned.
