Has everything been supplied?
Check the scope of supply:
■
Completely assembled transducer
■
Inspect the transducer for possible damage during transportation. Should there be any obvious damage, inform the transport company and WIKA without delay.
■
The UHP transducers are puried, evacuated and double-packed in clean rooms in a protec­tive atmosphere (clean room class 5 according to ISO 14644). Special plastic protective caps are used to protect the high-quality threaded connections (ttings). The gauges should remain in this special packaging until installation in order to prevent damage and contamina­tion. Therefore remove the ESD (Electro-Static-Discharge) protective foil only at the place of installation.
■
Keep the packaging, as it oers optimal protection during transportation (e.g. changing installation location, shipment for repair).
■
Ensure that the pressure connection thread and the connection contacts will not be damaged.
■
Remove this protection cap only just before installing the transducer.
■
Mount the protection cap when removing and transporting the instrument.
