2.3 Special hazards
WARNING!
■ 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 cables are connected to the current terminals.
■ Do not use the calibrator if it is damaged. Before using the
instrument, 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.
■ Observe the working conditions in accordance with chapter
3 "Specifications".
■ Always operate the pressure calibrator within its overload limits.
■ To ensure problem-free operation, only operate the instrument
on battery power. Only use the mains connection for charging the
instrument's batteries.
■ Inspect the test cables for damaged insulation or exposed metal.
Check the continuity of the test leads. Damaged test leads should be
replaced before using the instrument.
■ 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 instrument if it is not working properly. The instrument
protection might be compromised. If in doubt, have the instrument
checked.
■ Do not operate the instrument in areas with explosive gases, vapours
or dust.
■ 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.
■ To avoid false readings, which could lead to possible electric shock
or personal injury, replace the battery as soon as the battery indicator
appears.
■ In order to avoid any possible damage to the instrument or the test
equipment, use the correct leads, the correct function and the correct
range for the measuring application.
■ When screwing an adapter onto the NPT thread of the calibrator, a
sealing material must also be used (e.g. Teflon tape).
