Operation

Precautions

1.Do not over pressure the piston

2.Do not increase or decrease the pressure in the gauge rapidly. Always use a metering valve for flow control. If possible, hold a hand lightly on the weights to protect the piston from injury. The maximum rate is 0.7 MPa (100 psi) per minute.

3.Before operation, be sure the retaining ring of the high pressure piston is securely in place.

4.Do not operate the gauge with a dirty or sticky piston.

5.Do not rotate the pistons against the upper or lower stop longer than necessary because the bearings, of necessity, are not lubricated.

6.Because of extremely small tolerances between mating parts, every effort should be made to insure careful handling of gauge parts. All parts, especially those concerned with the piston and cylinder, should be kept scrupulously clean. Acid from finger prints can etch a piston or cylinder. Handle piston and cylinder using cotton gloves on the hands to prevent acid etching of piston and cylinder walls.

7.Pistons and cylinders are matched assemblies. Each piston will operate properly only in its particular cylinder.

8.Any sound which indicates metal-to-metal contact between the piston and cylinder is a signal for the operator to stop the gauge immediately. Failure to do so may cause damage to the piston and/or cylinder.

9.Always give the serial number of the instrument when ordering replacement parts.

10.The circular weight-loading table of the Low Range Piston must never be permitted to enter the bore of the mating cylinder. The assembly must always be handled as described in Chapter 6, Piston/Cylinder Cleaning Instructions. Precautions must always be taken to prevent uninformed and inexperienced persons from carelessly picking up this assembly for inspection.

11.The Low Range Piston/Cylinder (2460-5) must always be assembled in the cylinder housing with the O-ring relief on the cylinder in the downward position.
