Operation

Take a gas reading by positioning the end of the instrument’s

flexible probe near the area to be sampled.

The presence of a combustible gas is indicated by a column of

ten red LEDs and a speaker. The number of lighted LEDs

gives visual indication of the relative gas level, while the

speaker produces clicking sounds, similar to a Geiger counter,

that increase in repetition rate as the gas concentration goes

up in relation to the instrument’s gain setting.

The instrument’s sensitivity to gas concentrations is adjusted

by means of its thumb-wheel Gain control. Clockwise rotation

increases sensitivity, while counterclockwise rotation de-

creases sensitivity. The Gain control is useful in pinpointing

large leaks by starting with the control set to light 1 or 2 LEDs,

and then gradually rotating the control counterclockwise as

the probe gets closer to the leak.

4.3 Using the Earphone

The earphone is an optional accessory that provides private

monitoring of the Leakator 10, and is recommended for use in

high-noise environments. The earphone plugs into the side of

the instrument, just above the thumb-wheel control.

4.4 Turning OFF the Instrument

Turn OFF the instrument by rotating the thumb-wheel con-

trol counterclockwise until a click is heard. There is no need

to purge the instrument with fresh air before turning it off.
