CAUTION

GAS OVERPRESSURE

At no time should sample, zero or span gas inlet pressure exceed 69 hPa - gauge (1.0 psig). Damage to the Sensor may occur if this pressure level is exceeded.

CAUTION

SAMPLE FLOW

Do not test the sample pressure by blocking the exhaust. When the pres- sure is released the sudden surge of flow will spin the internal flowmeter off its bearings and destroy it.

c.LEAK TEST

The TO2 Analyzer Module is completely tested at the factory for gas leakage. The user is responsible for testing for leakage only at the inlet and outlet fittings on the rear panel. Caution: Do not expose the

Sensor to pressure in excess of 1.0 psig as this may cause damage.
