    keyword=e-arm Q1 alarms

    Speak to Javier about alarm problems of e-arm Q1; he thinks it is similar to
    h-arm Q1 earlier / last year: setpoint of dac and readback of adc are different,
    so the readback momentum is off > about 10^-3, and alarm goes.

    Suggested solution for now: wait after momentum changes until
    it stabilizes, then adjust current of supply by ratio of momentum
    wanted to momentum read back. This should give setting good to
    better than 10^-3 and we should be okay. Should typically be off about
    few tenths of amp, may be okay in some settings.
