User Manual

www.sisco.com sales@sisco.com +86 773-280-9002

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.

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.

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.
