16 • Setting the Bump Test and Calibration Parameters
5. Install a GX-2009 in the instrument cradle. The CHARGE LED will
begin to blink yellow. See “Charging an Instrument in a Calibration
Station” on page 35 for a complete description of charging the GX-
2009.
6. Press and hold the POWER MODE button on the GX-2009 until
you hear a beep, then release it. The GX-2009 will begin it’s power
up sequence (see exceptions below in step 7). If a successful
connection between the GX-2009 and the SM-2009U occurs, the
TRANSMIT screen will appear on the GX-2009 display.
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 and 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 before
connecting to the SM-2009U.
The failure screen will remain on the display while the unit is
connected to the SM-2009U and it is not possible to view or set
the bump test or calibration parameters.
