The pump diode current readout for diode box 3 has been mis-behaving for a while now.  This time it was caught in the
act.  The set diode current is 50.2 A.  The readout is clearly wrong, not least of which the power supplies cannot
deliver more than ~65 A but also the laser power does not vary during this time.

    Might be an intermittent fault with the Beckhoff terminal that reads the output of the power supply.
