With one hand supporting the meter, slide the probe up through the
packing Gland Assembly until the internal stop makes contact. Close
the Valve Shut-off handle by turning the lever 90˚clockwise to isolate the
sensor within the chamber of the Packing Gland Assembly. Then slightly
tighten the compression fitting to keep a seal in the chamber.
