Updating the Tested Sensors Setting
The tested sensors setting allows the user to control what sensors are tested during a
bump test or calibration that is performed using the SDM-2012. If Std is selected, only
the standard sensors will be tested during a bump test or calibration performed using
the SDM-2012. For a GX-2012, only the LEL/O
2
/CO/H
2
S channels will be tested. For
a Gas Tracer, only the LEL/O
2
/CO channels will be tested. If ALL is selected, every
sensor in the instrument will be tested during a bump test or calibration performed
using the SDM-2012. This will include the %volume sensor for a GX-2012 or Gas
Tracer and the ppm combustible sensor for a Gas Tracer.
NOTE: Even if the tested sensors setting is set to Std, all additional sensors
(ppm combustible and %volume) can still be tested using the
instrument’s Calibration Mode.
Do the following to set the sensors to be tested.
1. Turn on the SDM-2012 with an instrument and establish a connection between
them as described above in "Turning on the SDM-2012 with an Instrument".
The instrument will display the home screen.
2. Press and hold the EDIT ENTER button for 2 seconds. The instrument will
display the Edit Mode screen.
