2.0 Safety instructions
Read this manual carefully before using the instrument!
Please follow the instructions and procedures described in this manual. They are
aimed at allowing you to make the best of your signal calibrator and avoid any
personal injuries and/or damage to the instrument.
Disposal – WEEE Directive
The signal calibrator contains Electrical and Electronic circuits and must be properly
recycled or disposed of (in accordance with the WEEE Directive 2012/19/EU).
Warning
The signal calibrator is designed to calibrate and measure low voltage process signals.
To ensure the safety of the operator and the instrument,
DO NOT connect the signal
calibrator to input voltages above 30 Volts.
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, vapour, 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 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 a violent release of pressure in a pressurized system, shut off the valve and
slowly bleed off the pressure before you attach the pressure module to the
pressure line.

To avoid personal injury or damage to the calibrator, use only the specified
replacement parts and do not allow water into the case.
