Tips for Using User Mode

To scroll from one item to the next, press and release AIR. To reverse the scrolling 

direction:
a.  Press and hold AIR.
b.  Immediately press POWER MODE and then release both buttons.
c.  The scrolling direction returns to the original direction when you exit and reenter a 

menu.

To skip an item when a question is asked, press and release AIR.

To enter an item and to save any changes, press and release POWER MODE.

To change a flashing parameter, press and release AIR. To reverse the direction of change 

(ie. from increasing to decreasing or vice versa):
a.  Press and hold AIR.
b.  Immediately press POWER MODE and then release both buttons.

To exit an entered item without saving a change, press and hold AIR and POWER MODE 

for a few seconds.

Performing a Bump Test (BUMP)

Bump test the instrument before each day’s use with a known concentration of the target gas. 

The instrument does not need to be calibrated unless it does not pass the bump test. 
To bump test the SC-04, you need:

Calibration gas cylinder

0.25 LPM fixed flow regulator

Non-absorbent tubing

Calibration cup

1. Confirm that the SC-04’s calibration gas value matches the concentration listed on the 

calibration gas cylinder as described on pg.47.
