Refer to Chapter 6 (Maintenance) of this manual for a general discussion of instrument
calibration. Refer to the Hydra Series II Service Manual (P/N 688868) for complete
calibration procedures.

The CAL ENABLE control point is located in the lower-right corner of the display.
When the instrument is correctly calibrated, this control should be covered with a
calibration decal; removing the decal voids assurance of correct calibration.
