3. Mute function
The meter beeps every second to assure the meter
is in normal working status. The beeps frequency will
speed up while the detected gas concentration
becomes higher.
5
Meter does not turn on
a) Make sure you press "ON/OFF " key for more
than 200 mS.
b) Check the batteries are in place, good contact
& correct polarity.
c) Replace with new batteries and try again.
TROUBLESHOOTING
MAINTENANCE
7
The meter is warranted to be free from defects
in material and workmanship for one year. The
warranty covers normal operation and does not
cover battery, misuse, abuse, alteration, neglect,
improper maintenance, or damage resulting from
leaking batteries. Proof of purchase is required for
warranty repairs. Warranty is void if the meter has
been opened.
WARRANTY
Authorization must be obtained from the supplier
before returning items for any reason . When
requiring a RA (Return Authorization), please
include data regarding the defective reason, the
meters are to be returned along with good packing
to prevent any damage in shipment and insured
against possible damage or loss.
RETURN AUTHORIZATION
4. Leakage check
BATTERY REPLACEMENT
While the LOW battery LED is on, it is suggested to
always change fresh batteries to ensure the accuracy.
Open the battery compartment from the meter rear
side and replace with 4 new AA alkaline batteries.
Check if the sensor is in good contact. If LED is
still off, please return the meter to the dealer
for repair.
Ready LED isn't on after 60 seconds warm up
4) Sensor drift may occur when it is soaked or
splashed with water.
5) If water freezes on the sensing surface, the
sensor would crack and alter characteristics.
6) This meter requires to operate under around
21% ambient oxygen environment in order to
function properly. This meter cannot work well
in zero or low oxygen atmosphere.
Situations must be avoided
1) If silicone vapor is absorbed onto sensor
surface, the sensor will be coated. So, avoid
exposure to where silicone adhesives, hair
grooming materials, silicone rubber/putty
may exist.
1) Light condensation under indoor usage should
not be a problem for sensor. However, if water
condenses on the sensor surface for a while,
the sensor characteristics may still drift.
2) Sensor performance may be also affected if
exposed to a high density gas for a long time,
regardless of the power condition.
3) When meter is turned off for a long time, the
sensor may show a drift in resistance according
to the storage environment. So, the meter should
be stored in a sealed bag with clean air.
Note!!
The longer the meter off time, the longer
warm-up time required to stabilize the sensor
before usage. Turn on the meter often to ensure
the
warm up time is long enough.
accumulative
Situations to be avoided whenever possible
4) Regardless of power condition, when the
sensor is exposed in extreme conditions such
as very high humidity, extreme temp. or high
contamination levels for a long period of time,
sensor performance will be adversely affected.
To check the pipe leakage, follow the steps below.
Hold the sensor toward the pipe, slide slowly the
sensor along the pipe; repeat the procedure from
the other side of the pipe. When the sensor is close
to a leakage, the LED will light on corresponding
levels and beep frequency increases.
It takes at least 2 min. to wait for sensor recovery
after removing the sensor out of a leak point.
While earphone is plugged on, users will hear the
beeps only through the earphone.
To mute the beeper, just slide the mute switch ON.
2) High-density exposure to corrosive materials
such as H2S, Sox, Cl2, Hcl, etc. may cause
corrosion or breakage of the lead wires or
heater material.
3) Sensor drift may occur when the sensor is
contaminated by alkaline metals, especially
salt water spray.
