When measuring pressure, make sure that the process pressure line is shut off
and depressurised before it is connected to or disconnected from the pressure
module.
Disconnect test leads before changing to another measurement or generation
function.
Observe the working conditions in accordance with chapter "3. Specifications".
Always operate the device within its overload limits.
To ensure problem-free operation, only operate the ProcessCalibrator on battery
power. Only use the mains connection for charging the ProcessCalibrator's
batteries.
Do not apply a voltage greater than the specified voltage to the instrument. See
chapter "3. Specifications".
Make sure that the test probes never contact a voltage source while the test
leads are connected to the current terminals.
Do not use the calibrator if it is damaged. Before using the handheld pressure
calibrator, check that there are no cracks or missing plastic parts on the case.
Pay particular attention to the insulation of the connectors.
Select the proper function and correct measuring range for the measurement.
Inspect the test leads for damaged insulation or exposed metal. Check the
continuity of the test leads. Damaged test leads should be replaced before using
the hand-held pressure calibrator.
When using test probes keep fingers away from the test probe contacts. Keep
your fingers behind the test probes' finger guards.
First connect the common lead, and then the live lead. When disconnecting,
remove the live test lead first.
Do not use the hand-held pressure calibrator if it is not working properly. The
instrument protection might be compromised. If in doubt, have the instrument
checked.
Do not operate the calibrator in areas with explosive gases, vapours or dust.
To avoid false readings, which could lead to possible electric shock or personal
injury, charge the rechargeable battery as soon as the battery indicator appears.
In order to avoid any possible damage to the pressure calibrator or the test
equipment, use the correct leads, the correct function and the correct range for
the measuring application.
