VELOCITY Calibration Routine. For velocity calibration, a stable air flow is
required with a setting resolution of +/–0.2% of reading and a velocity
accuracy better than +/–0.5% of reading. Bacharach can supply an Open Jet
Wind Tunnel together with associated instrumentation suitable for this
purpose, please contact Bacharach, Inc. for details.
SERVICE AND RECALIBRATION: If a fault or the instrument’s calibration is
suspected, it should be returned to Bacharach, Inc. for repair or recalibration. In
any event, it is good practice to have the instrument checked at least once a
year. If an instrument is not working correctly or requires recalibration, contact
your nearest Bacharach Service Department.
