*1 Please consult about other specifications.
*2 Guaranteed only for STEC calibration condition.
*3 Guaranteed only for calibration gas (N2) and calibration condition. Depends on gas or usage condition, response time may be changed.
*4 Flow accuracy complies with SEMI E56-0309. Guaranteed for calibration gas (N2), full scale and pressure condition.
*5 A flow rate exceeding 100% F.S. cannot be guaranteed for accuracy.
*6 Please make a zero point adjustment for both pressure and flow rate in an actual-use environment to eliminate mounting operation effect.
*7 Reference value with standard fitting. ·In notation of pressure unit, (A) shows absolute pressure. ·SCCM is symbol representing the gas flow rate (ml/min, at 0°C 101.3 kPa) . ·F.S. is a percentage of the full scale and %R.S. is a percentage of the reading scale.
