are 0.25% of full scale. Gauges rated
at 10 000 psi / 700 bar / 35 000 kPa / 350 kg/cm
2
are 0.5% of full scale. All of the gauges can be ordered with or without calibration certicates. For detailed
information on the gauges refer to Figure 4 on page 27.
As a general rule, AMETEK, M&G test gauges should be tested and recertied every 12 months. Testers used frequently, or with dirty uids, should be tested
and certied at more frequent intervals. Master units, used infrequently with clean uid, may need to be tested and certied less frequently.
Note: It is not necessary to send in the pump if it is operating properly. Pumps may be refurbished at a nominal charge.
Note: In order to reduce process time and your overall cost, please do not send in any customized ttings, hoses, tools, or small miscellaneous parts.
