OPERATION
With a sensor life of more than 500 hours and a battery life of over
50 hours, very little maintenance is required to keep the LDA1000H
in top operating conditions. Below are the proper procedures to
follow when changing batteries and sensors.
Low battery indication:
When the batteries reach approximately 10% of capacity, the
green LED next to the symbol (
batteries, slide the bottom cover of the instrument backwards to
reveal the battery compartment. Replace the batteries with a new
set of (3) size "C" alkaline batteries.
Changing the sensor:
See page 10 for the sensor replacement diagram.
• Remove the sensor housing cap by turning it
counterclockwise.
• With a pair of tweezers or a needle nose pair of pliers gently
pull the sensor away from its socket.
• Inspect the inside of the sensor housing and verify that there
is an O-ring over the socket and that no dirt or debris is
present. If there is dirt or debris, gently pull the O-ring out, use
a dry cotton swab to loosen the dirt and blow with compressed
air. Clean the O-ring and replace.
Do not cover the O-ring with Vaseline or any other
lubricant.
• Install the replacement sensor. Orient the tab on the edge
of the sensor so it coincides with the groove on the side of
the housing and gently push the sensor in.
Do not use silicone based hand cleaners or lotions prior
to installing a new sensor as this will irreversibly affect
it's operation.
• Remove and discard the filter inside the sensor housing's cap.
Replace with a new filter disk, making sure no dirt, water, oil
or any other substance comes in contact with filter. In the case
of the J2791 sensor cap, it is recommended to first clean the
sensor housing's cap with alcohol or some other solvent which
does not contain oil or silicone. Use a cotton swab to first
loosen any debris from the cap's opening. Finish by blowing
with dry, oil-free, compressed air. Re-attach the cap to the
sensor housing, screwing it finger tight. The water vapor filter
cap should not be cleaned with solvents. Replace the paper
filter only.
Do not use acetone or silicone based solvents, lotions or
un-cured adhesives while handling the sensor.
