● INFLUENCE TO BODYWhen getting on an acute poisoning, headache, trouble walking, low bloodpressure, etc. will be caused. In case serious condition, unconsciousness orparalysis in breathing may bring death. Its accumulation in the body issmall and it would seem that chronic poisoning is an accumulation of
influence of sub‑acute operation. There are trouble of eyes, stomachtrouble, etc. as symptoms.

● OPERATION① Break both ends of generation tube with built‑in tip cutter on gas
aspirating pump, or with tip cutter attached to calibration gas set.
② Absorb water to the marked line on generating solution tube with soaking
A side printed on it.
③ Take out generation tube from generating solution, and wipe off water dropon the surface of generation tube with paper towel, etc.
④ After inserting the A side of generation tube into air feeding side(EXHAUST) of air pump (Feeder,etc.) until bag is inflated of the bag forcalibration with tube cock.
⑤ Operate air pump (Feeder, etc.) until bag is inflated completely, then stop
inlet of the bag for calibration with tube cock.
⑥ Connect detector tube No.120SB Hydrogen sulphide with the bag for calibra‑
tion, and confirm concentration inside the bag.
⑦ After confirming concentration inside the bag, complete calibration ofinstrument within 30 minutes.
