Special hazards

WARNING!

■

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 Multichannel Calibrator

model Pascal ET or Pascal ET/IS on battery power. Only use the mains
connection for charging the Hand-held pressure calibrators 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 multichannel

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 multichannel 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 multichannel 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 multichannel calibrator or the test

equipment, use the correct leads, the correct function and the correct range for
the measuring application.
