(1) The air filter is clogged as it is used for a long period of time. Change the air filter
element after two years of use or when the pressure drop reaches 0.1 MPa.
(2) Cleaning A/E converter
When the A/E converter is used for a long period of time, oil and dust may
accumulate in the air circuit. Clean the A/E converter as described below.
 Record the approximate installation position of the zero and sensitivity adjustment
knobs at the front of the instrument (or the distance of each knob from the edge).
This record facilitates mastering after cleaning.
 Turn the zero and sensitivity adjustment knobs counterclockwise, and remove
them from the instrument.
‘ Check the O-ring of each needle. If the O-ring is damaged, change it.
’ If the needle is dirty, clean it. Dampen a cotton swab with alcohol, and use it to
clean the φ3 mm hole into which the needle enters.
“ Replace the needle in each knob. If the split screw is loose, expand it with the tip
of a flat-end screwdriver. Take care not to overbend the split screw.
” Turn the needle of each knob clockwise, and install the knobs in the original
position recorded at first. Adjust the zero position and sensitivity of the air circuit
with the zero and sensitivity adjustment knobs, respectively, and calibrate the
instrument with the minimum and maximum masters.
