Users Manual

no parts to disassemble, no mechanical adjustments to make, and the instrument can be calibrated by an automated instrumentation system.

The instrument should normally be calibrated on a regular cycle, typically every 90 days or 1 year. The chosen calibration cycle depends on the accuracy specification you wish to maintain. The instrument should also be calibrated if it fails the performance test or has undergone repair.

Note

Do not press CAL ENABLE unless you have a copy of the Service Manual and intend to calibrate the instrument. If you have activated calibration and wish to exit calibration, press CAL ENABLE until CAL disappears from the display (or press power OFF).

Refer to the Hydra Series II Service Manual for the essential calibration procedures.

Variations in the Display

Under normal operation, the display presents various combinations of brightly and dimly lit annunciators and digits. However, you may encounter other, random irregularities across different areas of the display under the following circumstances:

∙After prolonged periods of displaying the same information.

∙If the display has not been used for a prolonged period.

This phenomenon can be cleared by activating the entire display and leaving it on overnight (or at least for several hours). Use the following procedure to keep the display fully lit:

1.With power OFF, press and hold K, then press power ON.

2.Wait a moment for the instrument to beep, then release K.The entire display will now stay on until you are ready to deactivate it.

3.At the end of the activation period, press any button on the front panel; the instrument resumes the mode in effect prior to the power interruption (Active or Inactive).

Service
