PLEASE READ CAREFULLY BEFORE USING
Anyone who may use, maintain or repair the instrument should read this operating manual
carefully and only follow the operating manual to achieve the design level. Otherwise the
instrument will not work properly and will cause malfunction and damage to the instrument.
Warning:
▲ The readings beyond the range indicate the concentration of the gas that may or will soon
reach the explosion concentration or the concentration of casualties.
▲ Replacing components can affect the intrinsic safety of the instrument.
▲ It is strictly forbidden to charge the meter in a hazardous area. Users must use the
special charger equipped with this unit.
▲ Do not disassemble, recharge or replace batteries in hazardous locations. ▲ Charging
must be turned off; the instrument must not be operated while charging or exporting data.
▲ Portable products, before entering the danger zone, doing electrostatic release of human body,
and then carries the instrument into the zone.
▲ Do not use the computer's USB interface for communication in hazardous areas. ▲ Old and
new batteries or batteries from different manufacturers cannot be mixed.
Attentions :
To ensure maximum safety and performance, please read and follow the items and conditions
listed below.
● The air intake of the sensor must be kept clean. Blocking the sensor's air intake
may result in readings that are lower than the actual gas concentration .
It is strictly forbidden to use compressed air to clean the air inlet of the sensor to avoid
damage to the sensor.
● Catalytic Principle Flammable Gas Sensor and Infrared Principle Sensor can only
accurately monitor designated gases. It should be noted, however, that the catalytic principle
flammable sensor is not specific to a particular gas and will be able to react to other flammable
gases.
● If the instrument is subject to physical impact or high pollution, the calibration
cycle needs to be shortened.
● The sensitivity of flammable gas sensors will be affected by high concentrations
of sulfides, halogen compounds, silicon-containing compounds, and gases containing "mercury"
and "lead", steam, and high temperature organic acid gases. Avoid using them in environments
containing the above chemicals. The instrument, if necessary, must be tested and calibrated after
use to avoid affecting the accuracy of the instrument.
● The instrument is strictly prohibited from being used in a high concentration of
flammable gas for a long time to avoid damage to the flammable sensor. If it is necessary, the
instrument should be tested and calibrated after use to avoid affecting the accuracy of the
instrument. If the flammable sensor is damaged, it needs to be replaced with a new one. The
new sensor can only be reused after it has been calibrated.
8
●Do not use organic solvents, soap or silicon-containing solutions to clean the
instrument to avoid damaging the sensor.
● When sampling with a sampling tube, do not use a sampling tube made of
silicone material or other sampling tubes that are not certified by the special source.
● A sudden change in air pressure or a blocked air circuit may cause temporary
fluctuations in the instrument's oxygen readings.
● Large changes in pressure will result in incorrect readings. If the measured gas
pressure is greater than 10% of the atmospheric pressure, it will affect the instrument reading
and even damage the sensor. The instrument should be re-calibrated and the measured gas
should be depressurized.
● It is forbidden to artificially use the gas shock sensor that exceeds the range of
the instrument. If the over-range high-concentration gas impact occurs, the
instrument must be re-calibrated.
● When replacing any one of the sensors, the instrument needs to be calibrated.
● Standard gas should be selected from the manufacturer or the nationally
qualified enterprise.
● The calibration should be in a well ventilated environment to avoid
contamination.
●It is strictly forbidden to calibrate the instrument under the condition of
insuffcient power supply.
● Do not use the instrument in an oxygen-rich environment.
● It is strictly forbidden to replace the components or structures that affect the
explosion-proof performance at will, so as not to affect the explosion-proof
performance.
● It is forbidden to expose the instrument to high concentration acid and alkali gas
to avoid damage to the sensor.
● It is strictly forbidden for users to repair or replace parts without authorization.
● A sudden change in temperature can cause the output signal of the infrared
sensor to be abnormal. After the transient is removed, the instrument will resume normal
operation and the ambient temperature change rate should be limited to 2 ° C / min.
●If the gas sample flow rate changes excessively, it will also cause the infrared sensor
output signal to be abnormal. After the transients are removed, the instrument will
resume normal operation and the gas flow rate should be kept below 0.6 L/min.
It is strictly forbidden to expose the infrared sensor to corrosive gas such as hydrogen sulfide.
It is strictly forbidden to cause condensation inside the sensor.
Condensation phenomenon inside sensor is strictly prohibited.
●
●
9
Calibration Warning:
●Gas detection equipment is a safe life-saving measuring instrument. To ensure
metering accuracy, toxic and catalytic principles flammable gas sensors should be
calibrated at least once every six months, while infrared sensors should be calibrated once
a year.
●The gas detector needs to be carefully tested or calibrated after an alarm
occurs.
●This instrument has the function of recording and querying the calibration date.
Please check it frequently. Not only do users need to understand the parameters of the
instrument, but they also need to understand the meaning of the test data obtained.

After loading the self-test interface, it will enter the sensor preheating interface, and there will
also be a countdown action. This action takes about 1-2 minutes. After the countdown, the
display interface will prompt whether the detector is performing fresh air/zero calibration.
