2.4 Improper use

WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
When measuring pressure, make sure that the process pressure line is shut off and depressurized 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 instrument within its overload limits.
■
To ensure problem-free operation, only operate the Multichannel Calibrator model Pascal ET, ET-P, ET/IS,
■
ET-P/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.
Any use beyond or different to the intended use is considered as improper use.
