1. Introduction
The CP 400/420 is designed to be a simple to use yet very versatile pressure calibrator. Its
two internal pressure sensors combined with inputs for mA, voltage, switch contacts and
an RTD probe allow the 400/420 to calibrate virtually any pressure device. An external
pressure module option allows an even wider range of pressure calibration options
including absolute and differential.
1.1 Standard Equipment
Check to see if your calibrator is complete. It should include: CP 400 or CP 420 calibrator,
instruction manual, test leads, carrying case, calibration certificate.
1.2 Safety Information
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.
- 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 measuring pressure, make sure the process pressure line is shut off and
depressurized before you connect it or disconnect it from the 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.
Caution
To avoid possible damage to calibrator or to equipment under test:
- Use the proper jacks, function, and range for your measurement or sourcing application.
