RKI Instruments SM-2003U - Manual (Page 10)

10 • Back Panel
Fuse & Power Cord Plug
A fuse holder is located to the right of the power switch. The fuse holder
consists of a panel mounting socket and a quarter turn fuse holder. The
fuse is a 2 amp, 5 mm x 20 mm fuse. A recessed 3-pin plug for the 115
VAC power cord is located to the right of the fuse holder.
NOTE: Although the SM-2001U and SM-2003U can operate
from 100 VAC - 240 VAC, the power cord supplied with
the calibration stations is a 115 VAC power cord. If you
wish to power a calibration station from 220 VAC, you
will need to provide an appropriate plug-in power cord.
Gas Sample Fittings/Air filter/Exhaust Tube
Four sample fittings are located on the back of each calibration station.
The AIR fitting is in upper left corner and draws air into the station. A
particle filter with a short length of tubing is supplied with each calibration
station for installation to the AIR fitting to keep particulate contamination
out of the calibration station. The CAL. GAS fitting is next to the AIR
fitting and is used to connect the station to a calibration gas cylinder. Both
the AIR and CAL. GAS fittings accept 3/16” ID tubing.
NOTE: The SM-2001U and SM-2003U are originally shipped
with a cylindrical air filter. If a replacement filter is
needed, the 33-0165RK disk filter is recommended.
A two port exhaust fitting is located in the upper right corner of the back
panel. It allows routing of the exhausted calibration gas to a convenient
exhaust location. The bottom port is plugged with a push-on plug that is
supplied with the calibration station and the top port is used for tubing
connection. This port accepts 5/16” ID tubing. A 10 foot long 5/16” ID
tube is included with the calibration station for routing of the exhaust.
Even though the exhaust gas can be routed to an area to be safely
dispersed, the docking station should still be installed in a well ventilated
area.
