Instructions for Use AMSCO®600 Medium 11050355_A
• PTE-2 Heise Gauge: Press the ZERO button while the results from the previous decay leak test are displayed
to run another decay leak test. A 60 second timer will start counting down on the Heise gauge. At the end of
the 60 seconds, the Heise will display a decay value. Make a note of the total decay.
Test Drain Piping
1. Turn on VP1 vacuum pump and S3 valve. Pull a vacuum on the test fixture and piping to the limit of system.
2. Close the ball valve on the test ports in the box going to the transducer port.
3. Turn off S3 valve and VP1 vacuum pump. Be sure to close S3 before turning off VP1.
4.
• PTE-1 Heise Gauge: Press the LEAK button on the Heise gauge until TIMING is displayed to leak test the drain
piping, steam piping, and transducer piping. A 60 second timer will start counting down on the Heise gauge.
At the end of the 60 seconds, the Heise will display a decay value. Make a note of the total decay.

Test Transducer Piping
1. Open all the ball valves on the test ports in the box except the one with no tubing connected.
2. Turn on VP1 vacuum pump and S3 valve. Pull a vacuum on the test fixture and piping to the limit of system.
3. Close the ball valve on the test ports in the box going to the drain port.
4. Turn off S3 valve and VP1 vacuum pump. Be sure to close S3 before turning off VP1.
