Preparation
The Hydraulic Comparison Test Pump User’s Manual covers the following instruments:
the P5514, P5514-V, and the P5514-EP.
The Comparison Test Pump is used for checking pressure-measuring instruments against
Master Test Gauges.
Note
The terms ”Master Test Gauge” and “Gauge” in this document refer to
any pressure-measuring instrument such as Transfer Standards, Digital
Calibrators, and Transducers.
This system is only as accurate as the Master Test Gauge used. The Master Test Gauge
must be regularly calibrated on a Primary Reference Standard (such as a Deadweight
Tester) to ensure accuracy is maintained.
The comparison test pump should be mounted securely to a stable workbench or similar
surface. Four mounting holes are provided in the pump stand for this purpose.
