2.1 Inspecting the Instrument
An inspection of the Micro Pressure Sensor before each use will assist in spotting problems
that could lead to inaccurate data or possible failure. Examine the outside of the shipping
case for evidence of heavy impacts during transport. If signs of damage are visible continue
with the inspection as follows and notify the carrier and the factory of any damage found.
Examine the cable for cuts or wear and check the connector ends for visible damage.
2.2 Connecting the Micro Pressure Sensor to a Computer
The user communicates with the Micro Pressure Sensor via any IBM-PC or compatible
computer or data collection device. An AML supplied data cable will link the two. Refer
to the wiring diagram in
Appendix ‘C’
. At one end of the cable is a DB25 or DB9 female
connector that plugs into the computer's serial port and at the other end is a 6 pin plug that is
inserted into the communications port of the Micro Pressure Sensor. When this connection
has been made and 8-26 volts DC applied, the instrument is powered up and ready to
communicate with the computer.
WARNING:
A plug or cable must be installed in the connector at all times when the instrument is
immersed in water. Failure to do so will cause corrosion to the connectors and may
cause water damage in the electronics housing
.
2.3 Powering the Micro Pressure Sensor
The Micro Pressure Sensor is powered externally via the communications cable. Refer to
the wiring diagram in
Appendix ‘C’
. The power should be 8-26 volts DC. If an AML data
cable is used, attach the red wire to the positive side of the power supply and the black wire
to ground.
