◆Prohibit drop from high space.
◆Under the high temperature or pressure is not allowed to use, if high
humidity, then need to add the device to decrese the humidity.
◆Human damage is not free repairment.
◆Befor enter into dangerous area, people need to be electrostatic
discharged, then bring the detector into the working place.
◆Using the special charger for this detector.
8.Common faults and treatments
◆ Value display not stable, up and down
Reason:some electrochemical sensor easily effected by other gas,
maybe is colorless and odorless.
Solution:Bring the detector into clean air, then the data will decrease to
normal value; If still not normal, then zero calibrate in clean air.
◆ Response weak
Reason:Lower level of oxygen:<5%VOL;
High pressure, pump not work;
The sensor useful life end, or other faults;
Solution : If the Electrochemical sensor, Catalytic combustion
sensor,Semiconductor sensor,need oxygen to work, so the
level of oxygen should more than 5%VOL,pressure range
is:-30Kpa ~ 100Kpa,If user have calibrate gas, can
import the gas to test and target point calibrate. If oxygen
and pressure both normal, then maybe other faults, need to
send back to manufacturer.
◆ After access the detecting gas, the data cann’t stable for a long time, up
and down
Reason:Maybe the too low content of oxygen in the detecting gas, or
the change of the detecting gas.
Solution:Increasing the oxygen level and keep stable flow rate, or
