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 PMT output in millivolts would be:
"T 194:11:29 0000 PMT= 254 MV<CRLF>"
To request a test measurement, the host must issue a command of the form:
"T MEASUREMENT<CRLF>"
For a summary of all test functions issue the command "T LIST". Table 7-8 lists the commands
and the corresponding test measurements which will be returned.
