39 • Connecting Instruments to the Data Cal 2000
NOTE:As soon as a DM-2003 docking module recognizes that a
GX-2003 is installed, a solenoid in the DM-2003 that
allows the GX-2003 to draw gas is opened. If a GX-2003
is installed in the docking module when the Data Cal 2000
is turned on, it takes the DM-2003 about 5 seconds after
turn on to recognize the GX-2003. The solenoid remains
open for 3 minutes and is then closed. Turn on all
GX-2003’s after this 5 second period and within 3 minutes
of the solenoid being opened. If the solenoid is closed
when the GX-2003 is turned on, it will go into low flow
alarm because the pump activates for a few seconds
before the GX-2003 is connected with the software.
If a low flow occurs when the GX-2003 is turned on,
disconnect the coiled hose from the inlet fitting, press the
RESET button to reset the low flow alarm, and when the
PC TRANSMIT STANDBY OK screen appears, reconnect
the coiled hose to the inlet fitting.
• A GX-2009 will begin its normal startup sequence and after a
few seconds, the display will indicate it is ready to communicate
with the computer:
NOTE: If the GX-2009 is left in the DM-2009 for a long period of
time, the dock pump will run for 12 seconds every 2
minutes in order to keep excess hydrogen generated
from the NiMH batteries from affecting the CO sensor.
