Turning on the SDM-2009 with an Instrument
Do the following to turn on the SDM-2009 and establish a connection with an
instrument:
1. Confirm that the AC adapter is connected to the SDM-2009 and to an AC wall
socket.
2. Press and hold the SDM-2009’s POWER button. The LEDs will turn amber.
3. When the BUMP T and CAL S LEDs turn off, release the POWER button.
4. The COPY LED will be steadily on or off and the CHARGE LED will be blinking
green if the SDM-2009 is operating properly or solid red if there is a system
failure. The amount of free memory in the SDM-2009 will dictate the condition
of the COPY LED (see “Available Memory in the SDM-2009” on page 38).
5. Install an instrument into the instrument cradle.
6. Press and hold the POWER MODE button on the instrument until you hear a
beep, then release it. The instrument will begin its power up sequence (see
exceptions below in step 7). If a successful connection between the instrument
and the SDM-2009 occurs, the home screen will appear on the instrument
display at the end of the startup sequence. The auto calibration values for all
installed sensors will be displayed.
NOTE: The screen shown above applies to a 4-channel GX-2009. If your
GX-2009 has less than 4 channels, the inactive channels will not
appear in the above screen or in any screens where channels are
displayed. All screens in this manual assume a 4-channel GX-2009.
7. There are two exceptions to the sequence described in step 6 above. See the
GX-2009 User Setup Program Operator’s Manual for a description of the Cal
Limit Display and Cal Limit Check instrument parameters.
• When Cal Limit Display is set to On and Cal. Limit Check is set to Can’t
Use, if the GX-2009 is due for calibration the instrument will show a
calibration expired failure screen and the buzzer and LED arrays will pulse
for a few seconds.
The instrument will then connect to the SDM-2009 and display the home
