Instruction manual

NOTE: Due to pulsations introduced by the Aspirator Bulb
Assembly, instability of readings may occur. Before
noting the readings, allow readings to stabilize for
three or four seconds after the bulb is squeezed.

CAUTION
Do not permit the end of the sampling line to touch or go
under any liquid surface. If liquid is sucked into the
instrument, readings will be inaccurate and the instrument
could be damaged. To prevent this, use Sample Probe (P/N
497600 or 800333) or an equivalent containing a special
membrane filter, permeable to gas but not to water.
