6 VDC Power adapter
On the portable model the AC Power Input Port is adjacent to the ON/OFF-BATT switch. On the wall mount
unit the input connection is on the right side the enclosure. See adjacent photo.
Note: Use only the correct power adapter for your location.
Gas Connections
Portable model:
The portable model is supplied with
a 3/16” vinyl hose connected to the inlet port and
adapters for taking a gas sample from the inflator
hose (See Figure 1). An optional flow restrictor is
available for sampling gas directly from cylinders.
(See Figure 2)
Wall Mount:
Do to the complexity of the wall mount
sampling system please refer to the user’s manual for
instillation details.
Calibration
Note: The sample gas must be flowing to accurately
calibrate the instrument
Oxygen sensor
1.
Using a source of dry air adjust the flow until you can just
detected the gas flow with your finger. Connect gas line to
the analyzer input port.
2.
When the oxygen display reading stabilizes (approximately
1 minute) adjust the oxygen display to read 20.9% using the
O2 Span control on the front panel. Note: The highest
degree of accuracy is achieved by using 100% oxygen and
adjusting the reading to 100.
Helium sensor
The Helium sensor is supplied fully calibrated and should not
require adjustment for approximately 30 days. For calibration
information please refer to the instruction manual
.
Operation
To operate the
PRO TRIMIX
1.
Turn the power on.
2.
Attach the sample line using the supplied adapters and
allow the gas to flow into the instrument at 1-2 LPM.
If the readings on the LCD display appear wrong shut
the gas off and observe readings. If they drop within a
few seconds the gas flow is too high. Reduce flow or
use the cylinder valve to turn the gas on and off until a
stable reading is achieved.
