Reference Manual Compact Pressure Calibrator AMETEK JOFRA CPC 􀂤 Copyright 2005 AMETEK Denmark A/S 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. 1.1 Contacting Ametek US, Canada, Latin America Europe, Africa, Middle East Asia AMETEK TCI at 1-800-527-9999 AMETEK Denmark A/S at + 45 4816 8000 AMETEK Singapore [Pte. Ltd. at](Pte. Ltd. at) + 65 (64) 842 388 1.2 Standard Equipment Inspect the unit carefully upon receipt. Save packing carton in case reshipment is necessary. If there appears to be any damage, equipment missing or if there are any questions about the unit, contact AMETEK. Check to see if your calibrator is complete. It should include: • CPC Calibrator • Instruction Manual • Test Leads • Carrying Case 1.3 Safety information Symbols Used The following table lists the International Electrical Symbols. Some or all of these symbols may be used on the instrument or in this manual. Symbol Description AC (Alternating Current) AC-DC Battery CE Complies with European Union Directives DC Double Insulated Electric Shock Fuse PE Ground Hot Surface (Burn Hazard) Read the User’s Manual (Important Information) Off On 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 ap

FAQs

What does the AMETEK JOFRA CPC calibrator measure and verify?

It is designed to verify and calibrate pressure gauges, transducers, pressure switches, safety valves, and P/I transmitters. It also performs pressure switch tests and measures current and pressure simultaneously.

What are the safety rules for using the calibrator?

Use the calibrator only as specified, avoid electric shock risks (e.g., do not exceed rated voltage and follow equipment safety procedures), inspect for damage, and use proper battery and test lead handling. Follow cautions such as the “OL” range limit behavior and maximum torque limits.

How are the calibrator displays used during measurement?

The calibrator has two numeric displays: a large display for measured pressure and a small display for measured current. Current may be shown in mA or as a percentage of the 4–20 mA range.
