The refresh frequency is 1HZ. Do not charge in the process of measuring the flammable gas or explosion may occur. High/low alarm: 4 default values for high/low alarm with 4 forms of alarm and the alarm voice can be turned off. Data record: up to 1000 pieces of data recorded allowable. The default interval of data record is 5 seconds which can be set in the inL in the set mode. When the interval is set as 0 second the data record function fails. Delete operation will delete all the data recorded. Temperature display: to set the unit as or , default unit is Automatic turning off: the unit turns off within 30 minutes if there is no further operation. Default turning on is this function. Battery volume: if the volume is the last bar or less it is highly recommended to charge the unit. It is forbidden to activate the unit to operate lest the possible measure error or explosion. If the battery is low it may turn off automatically. Charging time: about 4 hours. Discharging time: about 8 hours. Calibration of 0 point: it is recommended that the unit should be calibrated at the 0 point every month or if there is zero shift occurring to ensure the high accuracy of the measurement (please be sure that the battery volume is above 2 bars while calibration, and put the unit in the air for a while after turning on to ensure that the unit has its body temperature a little bit higher than the environmental temperature. Temperature compensation: the data measured is compensated at the range of -20 to 50 MAX/MIN/hold reading: press the button to calculate. Software error: the unit's crash/turn-off indicates the mistake occurs in process of operation. Press the on/off button to activate the unit if it is forced shutdown by software. -05- Specifications Compound Gas Monitor range Measuring item Unit Range Combustible gas LEL %LEL 0~100 Oxygen O2 %VOL 0~30 Hydrogen sulfide H2S Carbon monoxide CO * 1 P P M = 1m o l / m o l PPM PPM 0~100 0~1000 Resolution 0.1 0.1 0.1 1 Accuracy ±5%FS Response time (90%) Less than 30 seconds Indication mode LCD displays real-time data and system state, LED, sound, vibration indication alarm Storage Conditions Temperature:-10~55; Humidity:85%RH Temperature:- 20~50; Operation Conditions Humidity: 95%RH non-condensing Working voltage Charging time Standby time DC 3.7V (Lithium battery capacity 1800mAh) 4h More than 8h on end (slightly change with working state) Dimensions Weight 71*153*49mm 218.7g With battery -06- 2.Operation manual Main interface 1.

When the number of battery packs is full and no longer changes dynamically, charging is completed.Then you can unplug the charger.Reactivate the unit, the meter can be used normally. -13- Warnings and Precautions Improper operation or environment may cause accidents. 1. The instrument is strictly prohibited from collision, falling from high places or violent vibration. 2. If there is gas of high concentration, the instrument may not work properly. 3. Please operate and use strictly in accordance with the instructions, otherwise it may result in inaccurate test results or damage to the instrument. 4. Do not store the instrument in the following environments: a. Places that may have water or heavy dust. b. The instrument must not be stored and used in environments that contain corrosive gases (such as salt or sulfur in high concentration,etc.). c. Air with other gases or chemicals. d. Places of high temperature, high humidity or direct sunlight, including environments of too high and low temperatures, high humidity,electromagnetic fields, and strong sunlight. 5. Cleaning of the instrument's surface: a. The window of the sensor must be kept clean. If it is dirty, the measurement will be inaccurate. b. Please wipe it gently with a clean, soft cloth dampened with water (do not use alcohol, diluent, etc. to clean the case, especially for the LCD window.). 6.
