Built-in safety tests
Carry out the safety tests integrated in the ROTEST GW 150/4 before commissioning the
instrument and in regular intervals. Ensure that the instrument is functions properly before use.
4.1
Built-in hand pump (3) and connecting hose (6) test
Close all cut-off valves on your ROTEST 150/4.
Insert connecting hose (6) to connecting valve A. An auditable sound is heard when hose
and valve nipple are properly locked.
Use hand pump to increase system pressure to 0,3 MPa (3 bar).
Wait 10 minutes for loaded air and water temperatures to equalize.
Prolong period of temperature equalization if temperatures fluctuate greatly!
Carry out test over a period of ten minutes. The indicated pressure should not drop over a
10 minute period.
4.2
Built-in bellow (12), water column and connecting hose (6) test
Close all cut-off valves on your ROTEST GW 150/4.
Insert connecting hose (6) to connecting valve B. An auditable sound is heard when hose
and valve nipple are properly locked.
Assemble tube element system as follows:
while carefully turning insert tube element (8) with scale 41-75 hPa (41-75 mbar) into fixed
tube element (7).
while carefully turning insert tube element (9) with scale 81-115 mbar hPa (81-115 mbar)
into tube element (8).
Open connecting valves B,C and D.
Use bellow (12) to load a pressure of 150 hPa (150 mbar) into the test system.
Close connecting valve C to avoid a loss in pressure.
Wait 10 minutes for loaded air and water temperatures to equalize.
