11. Press and briefly hold the POWER button until you hear a beep to turn
on the SC-01. After a few seconds, the screen shown on the left below
will appear with the “S-CH” flashing indicating that the sensor has been
changed. After a few seconds, the two screens will begin alternating. In
the example below, the target gas is SO
2
.
12. Press and release the POWER button and the startup sequence will
begin as described in “Start-up Procedure” on page 10. At the end of
the startup sequence, instead of entering Measuring Mode, the SC-01
will proceed automatically to the AIR CAL menu item in Setup Mode.
13. If the sensor calibration is due or if you are not sure that the sensor has
been recently calibrated, calibrate the new sensor as described in
“Performing a Fresh Air Adjustment” on page 23 and “Performing a
Span Adjustment” on page 24.
If you do not want to perform a calibration, press and release the AIR ▼
button until you arrive at the START screen, then press and release the
POWER button to enter Measuring Mode.
Changing the SC-01’s Target Gas
The SC-01 sensor stores various parameters including the target gas,
detection range, and alarm points. Because of this, the sensor type can be
changed on the SC-01 without any setup required to begin monitoring for a
different target gas if the sensor is replaced with one of a different type as
long as the new sensor is calibrated.
To change the SC-01’s target gas, replace the sensor as described above
in “Replacing the Sensor” with a sensor of a different type. For example, if
you have an SC-01 for SO
2
and you want to change it to detect NH
3
, just
replace the SO
2
sensor with a NH
3
sensor and calibrate the new sensor if
necessary.
