AT-2000R/RQ Specifications
Note: All specifications apply over the standard 0oC to + 50oC operating temperature range, after a
minimum of 2 hours of storage within the operating temperature range, if the unit is not fully at
ambient temperature. The AT-2000R/RQ meets all it’s specifications within 1 minute after it is
turned on, providing that the AT-2000R/RQ is within the one year calibration cycle. Avantron's
unique AutoCal feature assures accuracy by periodically self-testing itself and triggering a nonobstructive calibration, as required.
