Frequency of Recertication
Four test gauges are included with each T-3 Comparator. Gauges rated up to 5000 psi / 350 bar / 21 000 kPa / 210 kg/cm
2
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 certicates. 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 recertied every 12 months. Testers used frequently, or with dirty uids, should be tested
and certied at more frequent intervals. Master units, used infrequently with clean uid, may need to be tested and certied 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.
