3. Confirm that the regulator on/off knob is turned all the way clockwise
(closed) and screw the calibration gas cylinder onto the regulator. Be
sure to use the regulator that generates the required flowrate for your
target gas specified in Table 5 above.
WARNING: If the wrong flowrate is used to calibrate your SC-01, the
calibration will not be accurate.
4. Push the calibration cup into the sensor retainer over the sensor face.
5. At the SPAN CAL screen, press and release the POWER button. A
screen appears that displays the calibration gas concentration that the
SC-01 expects you to use.
If the displayed concentration matches the calibration cylinder
concentration, continue with the next step.
If the displayed concentration does not match the calibration cylinder
concentration, do the following:
• Simultaneously press and release the AIR ▼ and ▲ DISP buttons.
The displayed gas concentration will begin to flash.
• Use the AIR ▼ and ▲ DISP buttons to adjust the displayed gas
concentration to match the calibration cylinder concentration.
• Press and release the POWER button to accept the displayed
calibration gas concentration. The unit will return to the SPAN
VALUE screen.
6. Press and release the POWER button. The current gas reading will be
displayed and “SPAN CAL” will begin to flash.
