§3 Preparation
3-1 Preparation to be executed first after installation
When this tester is used for the first time after mounting (or relocating) it, perform the following
preliminary operation and confirm its operation according to the following procedure.
1) Power supply
A single-phase 220VAC power supply is necessary as the control power supply for this tester. An
earth plug is mounted at the tip of the power cord of the control unit Connect the earth to the
ground without fails.
2) Pneumatic pressure source
Pneumatic pen cylinders are used for fixing a specimen. Feed the air pressure from the
compressor
(option) or indoor piping (higher than 0.49MPa) in a building.
The air pressure supplied to the tester body is regulated by a filter regulator. The regulated air
pressure operates the pneumatic pen cylinders through the solenoid valves. Since the air pressure
system is operated by feeding power supply, the pneumatic pen cylinders are controlled to fix a
specimen so long as the air pressure is supplied when turning off the power supply.
If the compressor (option) is provided with a start/stop (ON/OFF) switch, turn on the switch before starting the test.
