Air Filter and Exhaust Tubing
A cylindrical particle filter with a short length of tubing is supplied with the SDM-3R for installation
to the AIR fitting on the back panel. The filter keeps particulate contamination out of the docking
station.
A 10 foot length of 5/16 inch ID polyurethane tubing is provided for connection to the exhaust fitting
on the back panel to allow routing of the exhaust to a location such as an open window where the
exhaust can disperse.
WARNING:
Do not use an exhaust tube that is longer than 15 feet. The increased flow
restriction caused by a longer tube may affect gas response and cause inaccurate
calibration and bump test results.
Single-Station AC Adapter
The single-station AC adapter is a wall plug style adapter with a 4 foot cable. The end of the cable has
a plug that connects to the SDM-3R’s power jack. A screw included with the SDM-3R allows you to
secure the plug to the SDM-3R’s jack if desired. The AC adapter is rated 100 - 240 VAC input, 5.99
VDC 2 A output.
