J. Kissel I've grabbed traditional "charge" (effective bias voltage due to charge) measurements from H1 SUS ETMX and ETMY this afternoon while under an earthquake. Measurments show that the effective bias voltage is still holding around / under +/-10 [V] in all quadrants. Nice! Still on the to-do list: compare this against longitudinal actuation strength measurements via calibration lines, a. la. LHO aLOG 24547. Perhaps our new years resolution can be to start this regular comparison up again.
