appear, as shown in the right figure.
2. The current date and time are
displayed on the upper left corner.
If the time is incorrect, enter the settings interface to set.
3. The battery level is displayed on the upper right corner. When the
remaining power is low, the battery indicator will turn red. When the
power level is detected to be too low, the instrument will start 10s
countdown for automatic shutdown. The countdown second will be
displayed on the left side of the battery indicator. After the countdown is
over, the instrument will automatically shut down.
4.The main menu has 6 icons, namely, single measurement, multiple
measurement, viewing records, alarm settings, syste settings,
calibration.

Single Measurement Interface
1. This interface only displays single
measurement values; the left side
shows the maximum minimum,
and average value,where the
average value is the value mea-
sured in the last 4 minutes; the right
side shows the high and low alarm
values, and the middle shows
real-time values.
2. When checking oxygen
concentration, if the concentration
value is lower than the low alarm value, the instrument will trigger low
alarm state. If the concentration is greater than the high alarm value,
the instrument will trigger high alarm state; for the concentration of
gas other than oxygen, if the concentration value is greater than the low
alarm value,the instrument will trigger low alarm state. If the
concentration is greater than the high alarm value, the instrument will
trigger high alarm state.
3. In alarm state, Danger icon shows up; otherwise, Safety icon is
displayed.
4. In the alarm state, if the alarm is triggered, an alarm will be issued and
the alarm will be issued when the alarm is high.The alarm in high alarm
state shows more urgency and faster frequency than that of low alarm
state.
5. The alarm has three forms, light flashing alarm, sound alarm and
vibration alarm, which can be turned on/off in the alarm setting.
6. The lower left corner of the screen shows the lower limit of the range,
the lower right corner shows the upper limit of the range, the lowermost
triangle indicates the color of real-time value.

2. There are three alarm modes: light,
sound, and vibration, which can be
respectively set to be on or off.
When the real-time measured value
is greater than the high alarm
value or low alarm value (for oxygen
when it is lower than the low alarm value), the alarm which is set to be on
will be triggered.

English; date and time can be set
as year, month, day, hour, minute;
if auto storage is on, the measured
data will be automatically saved
according to the set recording interval. If not, it will not be stored
automatically; if the auto off is on, if there is no button operation within
the set shutdown time, it will automatically shut down. If auto off is not

time (including calibration parameters) in the instrument can be restored
to factory state;
1. First enter the sensor calibration selection interface shown in Figure
8.1. Press“ ”/“ ” button to select a sensor; then press “ ” to
enter the single sensor calibration interface, as shown in Figure 8.2;
2. In the interface of Figure 8.2, the left side is the calibration point option,
the right side is the calibration parameter corresponding to each
calibration point, and the lower right area shows real-time value,
minimum value, maximum value, average value and curve of the sensor
signal; the concentration setting refers to setting the concentration value
to be calibrated; calibration AD value refers to the signal value output by
the sensor corresponding to the set concentration value; offset
adjustment refers to the reading plus or minus the set deviation on the
basis of the calibration point; timing calibration means that after the
timing calibration is on, the countdown of the set timing starts. When the
countdown reaches 0, the measured signal value is automatically stored
in the calibration AD value. Manual calibration means that when the
manual calibration is on, the real-time signal value is stored in the

calibration AD value by pressing “ ”button; the value between manual
calibration icon and ENTER icon is the real-time measured concentration
value.
Three Sensor Calibration Methods
1. there are three kinds of calibration methods:
1) Input the calibration AD value directly: a. Set concentration value;
b.Open to calibration gas which has set concentration value; c. Wait for
the signal curve at the lower right of screen to be stable; d. After the
signal is stable,input the real-time signal value to calibration AD value.
2) Manual Calibration: a. Set concentration value; b. Open to the
calibration gas which has set the concentration value; c. Wait for the
signal curve at the lower right of screen to be stable; d. After the signal
is stable, select manual calibration. Press “ ” button to confirm that
the icon will be selected. Press “ ” button again and the real-time
signal value will be added to the calibration AD value.
3) Timing calibration: a. Set the concentration value; b. Open to the
calibration gas with the set concentration value; c. Select timing
calibration, press “ ” button, input the timing, then countdown
starts, when the countdown reaches 0, the real-time signal value will
be added to the calibration AD value.
4) If the calibration is wrong, you can recalibrate or restore to factory
settings in system settings.
2. When calibrating the zero point of carbon monoxide, hydrogen sulfide,
and combustible gas, you can increase the calibration AD value by 5~9
to prevent the readings from appearing unrecoverable.

Charging function description
When the power is insufficient or the voltage cannot be turned on
due to undervoltage, please charge in time and charge it.During the
charging process, the alarm light will flash and the meter will no longer
detect the gas concentration and display the number of battery packs
dynamically. When the number of battery packs is full and no longer
changes dynamically, charging is completed.Then you can unplug the
charger, the meter can be used normally.To speed up charging process,
the screen will turn black after 10s of no operation.At this time, the
charging interface can be resumed by pressing any button. When the
power reaches 80% and there is no operation in 2 mins, the instrument
will automatically shut down for charging.
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
