SC-100A manual

Version 3.1c
Setup
Setting up the SC-100A for the first time:
1.
The SC-100A (Figure 1) runs on two standard AA batteries (alkaline cells recommended). To
insert the batteries, open the battery housing on the bottom of the back of the unit by removing the
two screws and gently prying off the lid. Install the batteries, then close the housing. If desired,
you can prop the unit up using its folding stand.
2.
Low Battery Detection: When the battery level is getting low, the instrument shows a low battery
icon on the upper left side of the display but continues to operate without impairment to any
function. Replace the batteries as soon as practicable. When the battery level drops too far, the
instrument does not operate. It rapidly flashes the low battery icon for 3.0 seconds, beeps and
shuts itself off.
3.
Auto Shut-off: The SC-100A shuts off after 30 minutes. If this happens unexpectedly, just press
the POWER button to resume from where you were.
4.
The SO
2
electrode is attached via the BNC connector protruding from the top. To ensure proper
function, ensure the BNC is tightened around the SO2 electrode termination. (Figures 2 & 3).
5.
SO
2
Electrode: Remove any protective cover from the electrode tip (most electrodes are shipped
without one). Put the electrode on its side, or hang it from an electrode stand if you have one. The
SO
2
electrode is sturdy with its plastic housing, but do take care not to let things touch or strike
the platinum wires; they are somewhat fragile and will break if bent and straightened repeatedly.
Electrode care:
When done, always rinse with DI water and let air dry. There is no need to store
any electrode in any kind of solution, and the protective cap should not be replaced.
