Choose
L.P.
via S in the main menu, press E, then operate as showed. If it
discovers gas pipeline leakage, then promptly, “leakage” will be shown in the display
monitor.

when starting HC remained check, if discovers gas pipeline obstruction to cause
the flow excessively to be low, then “gas pipeline obstruction” will be shown on the display
screen.
After gas pipeline obstruction appears, you may choose
CLS
in the main menu and then
press E again, “gas pipeline obstruction” on the display screen will be eliminated.

In test process after starting HC remained check, if it examines HC remained
exceeding the allowed figure, then it can prompt “HC remained “on the display screen.
When one of the above four kinds of breakdowns appears, it will affect the normal use of
the instrument, which will create unable to enter the test process normally. At that time,
inspect it and exclude the breakdown and then can use it normally.
2 Other breakdowns diagnose
2.1 display screens not to be bright
Please inspect whether the power source plug has been inserted right, and whether the
power fusehas been damaged.
2.2 air pumps do not work or the reserving valve do not act
When entering zeroing process, you do not hear “toot toot” sound and “pa” sound, it
means the air pump and (or) the reserving valve doesn’t work normally. Please have an
inspection to the corresponding segment and the plug place.
2.3 data is not normal
Data are small, so first should inspect whether the air pump flow reduces. If yes, it must be
