The power glitch yesterday tripped the high voltage for the OMC and PMC. DIAG_MAIN had a test for the OMC, but not the PMC. Until now! Jenne requested this in alog23493 and it has been loaded in and committed to the svn.

Code below:

@SYSDIAG.register_test
def PMV_HV():
    """PMC high voltage is nominally around 4V, power glitches and other 
    various issues can shut it off.
    """
    if -0.5 < ezca['PSL-PMC_HV_MON_AVG'] < 0.5:
        yield 'PMC high voltage is OFF'
