Doing the gather load data diagnostic

This test checks the current draw on the dynamic disable (DD) and transmit/receive (TR) bias lines. Run this test to troubleshoot intermittent problems and collect baseline data on any new surface coil.

• Driver module
• Cables
• Connectors
• Coil (if connected)

None

The data is sampled five times for each line, and then written to two text files in /usr/g/service/log, Default-DD.txt and Default_TR.txt. Use the more or cat commands to view the content of the files.

The data in each file is reported in open (forward bias) and short-circuit (reverse bias) modes. These modes refer to the fault conditions for which the driver module is always monitoring.

Values much greater than the typical values may indicate circuit damage or a short-circuit condition somewhere in the bias path. Values much less than the typical values may indicate circuit damage or an open-circuit condition (maybe a disconnected cable) somewhere in the bias path.

Example of data

  Driver, mA1, mA2, mA3, mA4, mA5
            
            Head_P1_Short, 2, 2, 2, 1, 2
            
            Body_Short, 0, 0, 0, 0, 0
            
            MNS_ConA_Short, 0, 0, 1, 0, 1 (Ignore this due to SIGNA Pioneer not having MNS ConA port)
            
            Head_ConA_Short, -286331154, -286331154, -286331154, -286331154, -286331154 (Ignore this due to SIGNA Pioneer not having Head ConA port)
