Compact Pressure Calibrator

AMETEK JOFRA CPC

1. Introduction

The AMETEK JOFRA CPC is designed to verify and calibrate pressure gauges, transducers, pressure switches, safety valves, P/I transmitters, perform pressure switch tests, and measure current and pressure. Current and pressure measurements are simultaneously displayed on the calibrator. The calibrator can measure vacuum and pressure up to 10 psi / 0.7 bar, 30 psi / 2 bar, or 200 psi / 15 bar depending on sensor type and current up to 24mA.

Canadian Standards Association

This calibrator must be recycled or disposed of properly (2002/95/EC).

The following definitions apply to the terms “Warning” and “Caution”.

• “Warning” identifies conditions and actions that may pose hazards to the user.

• “Caution” identifies conditions and actions that may damage the instrument being used.

Use the calibrator only as specified in this manual, otherwise injury and damage to the calibrator may occur.

Warning

To avoid possible electric shock or personal injury:

• Do not apply more than the rated voltage. See specifications for supported ranges.

• Pressure switches must not be connected to any other voltage source during a test.

• Follow all equipment safety procedures.

• Never touch the probe to a voltage source when the test leads are plugged into the current terminals.

• Do not use the calibrator if it is damaged. Before you use the calibrator, inspect the case. Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the connectors.

• Select the proper function and range for your measurement.

• Make sure the battery cover is closed and latched before you operate the calibrator.

• Remove test leads from the calibrator before you open the battery door.

• Inspect the test leads for damaged insulation or exposed metal. Check test leads continuity. Replace damaged test leads before you use the calibrator.

• When using the probes, keep your fingers away from the probe contacts. Keep your fingers behind the finger guards on the probes.

• Connect the common test lead before you connect the live test lead. When you disconnect test leads, disconnect the live test lead first.

• Do not use the calibrator if it operates abnormally. Protection may be impaired. When in doubt, have the calibrator serviced.

• Do not operate the calibrator around explosive gas, vapor, or dust.

• When using a pressure module, make sure the process pressure line is shut off and depressurized before you connect it or disconnect it from the CPC or pressure module.

• Disconnect test leads before changing to another measure or source function.

• When servicing the calibrator, use only specified replacement parts.

• To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator appears.

• To avoid personal injury or damage to the calibrator, use only the specified replacement parts and do not allow water into the case

Caution

To avoid possible damage to calibrator or to equipment under test:

• Disconnect the power and discharge all high-voltage capacitors before testing resistance or continuity.

• Use the proper jacks, function, and range for your measurement or sourcing application.
