TROUBLESHOOTING
Unstable Pressure
X Problem: Pressure cannot be generated correctly, or set pressure does not remain stable.
X Solutions:
•
Check that all adapters and pressure fittings have been tightened sufficiently to eliminate leaks.
•
Confirm test fluid does not contain air (air in the fluid can increase adiabatic effects). You may have to adjust the pressure a few times before the
pressure is stable enough for calibration. Replace test fluid if necessary.
•
Adiabatic and thermodynamic effects may be affecting the pressure reading. High pressure hydraulic systems are sensitive to temperature and move-
ments. This effect will disappear after a period of time.
If the pressure is still not stabilizing, the system may be in need of service. Please contact your local distributor for advice.
Note: Always readjust the pressure after 5 to 10 minutes to allow time for settling of above effects.

MAINTENANCE
Users should/must carry out the following cleaning procedures when required:
Standard exterior cleaning . . . . . . . Clean using a soft, damp cloth.
Heavily soiled cleaning . . . . . . . . . . . The instrument may also be cleaned using isopropyl alcohol when heavily soiled.
Reservoir . . . . . . . . . . . . . . . . . . . . . . . . Can be removed for easy cleaning. Turn the GaugeCalHP onto its side and loosen the two screws holding the reservoir in
place. Slide the screws through the hole and quickly remove the reservoir as fluid may leak out of the bottom.
To clean the clear acrylic reservoir tube use a soft cloth or soap and water only. Never use chemical cleaners.
