SISCO SKY8000 User Manual

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 or even the 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 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.
