4-1. Introduction
This section of the Service Manual provides performance tests that can be used at any
time to verify that Hydra (2620A, 2625A, or 2635A) operation is within published
specifications. A complete calibration procedure is also included. The performance test
and, if necessary, the calibration procedure can be performed periodically as well as after
service or repair.
