Setting up T1 diagnostics
The diagnostic tests available for T1 include:
• RAM - During the RAM test, the memory on the T1 measurement module is
tested. Any memory hardware failures are detected.
• ROM - The ROM test verifies the integrity of the code by performing a
checksum measurement.
• Loop Back - The loop back test is a functional test of the transmitting and
receiving hardware. It attempts to send various signal patterns and levels and
then to verify the measured values. It is important that this test be done using
short bantam jumpers (plugs) as even a 1.2 – 2.0 meter (4 – 6 foot) cable can
reduce the signal levels during the diagnostic tests, and this can cause a false
failure.
If any of the above tests fail, contact your service center.
