WARNING
Read and understand this instruction manual before operating instrument.
Improper use of the gas monitor could result in bodily harm or death.
Periodic calibration and maintenance of the gas monitor is essential for proper
operation and correct readings.Please calibrate and maintain this instrument
regularly!Frequency of calibration depends upon the type of use you have and the
sensor types.Typical calibration frequencies for most applications are between 1
and 3 months,but can be required more than or less often based on your usage.

CAUTION:
1. All operations are operate by a short press of the button unless it is special noticed
2. GT-1000 series multifunctional gas and dust detector could be work normally only in condition of the pump was switched on
②Gas Detector Processing Operation under Out-range Status
Users should avoid to have sensor impacted by the gas with a pressure value greater than the maximum of the detector, which might
affect the service life and precision of the detector, or even directly damage detector.
When a user accidentally makes out-range operation, he should evacuate the instrument out of the detecting site and place it in the
clean air for more than half an hour. During the time, user should observe whether the density value of the instrument is keeping
decreasing or not. If it can straightly go down to normal value, then he can continue to use it after the zero calibration of instrument.
While the instrument after the out-range operation and user has placed it in clean air for hours, the density value remains high, then
it should be sent back to the manufacturer or agent for maintenance, be ready to replace the sensor.
Special Note: Detector damage resulted from out-range operation is not within the warranty.

③Detector Calibration and Warranty
We guarantee all detector were precise calibrated with certain density standard gas. It’s not necessary for customer to re-calibrate
the detector after purchase unless encounter special situation. Also the calibration need to be operate under the guidance of the
professional.
All GT-1000 series products we provide 12-Mounths warranty for the detector and 3-Mounth warranty for the accessories. Beside ,
we have free calibration once a year during the entire products service life.
④Instruction of detector display dimmed
Power capacity protection program had been preset for all GT-1000 multifunctional gas detector, when no operation were made
within 30 seconds the protection program will activate and the display of the detector will dim out,user can light up the display by
press power button.
⑤GT-1000 series Hot Key Instruction
Mute: When detector is in the state of alarming user can mute the detector by pressing the “Up”or “Down”button.
Save manually:When storage mode was preset as manually, user can save the gas concentration value of each channel by long
press the “Up” button in detection interface
Function menu: When detector is in the detection menu user can enter system menu by pressing “Ok” button for 5 seconds
When gas concentration reach the alarming value and triggered the alarm,user can mute the detector by pressing Up or Down
button(Press to mute and press another time to restart the alarm)

6.2.4 Zero Calibration
If zero drift of the sensor is over range, user can proceed zero calibration ,the gas concentration are defaulted set to zero after zero
calibration as shown in figures 30.
Special Note: 1.Zero calibration must be proceed in fresh air or high-purity inert gas(for example 99.999%VOL N2 etc)
2.Do not operate zero calibration for those gases which already exist in the air,such as oxygen,carbodioxide,nitrogen.
6.2.5 Target Calibration(Do Not Calibrate Unless You Are Professional)
Find a fresh-air environment.This is an environment free of toxic or combustible gases and
a normal oxygen content(20.9%VOL)
GT--1000 series gas detector provide 6 levels target gas concentration calibration,as shown in figure 31-32,this calibration should be

operate under conditions of certain standard concentration gas, Pressure reduction valve ,Flow meter, Calibration cover and make
sure all instruments are well connected, otherwise this function is forbidden.
Procedures: Connect all instruments as shown in figure 33,enter target gas calibration interface,release standard gas slowly and
control gas flow within 600ml/min,observe the real-time concentration value(concentration value should be increasing),wait until
real-time concentration value rise to the peak reading and stay still, user can chose a un-calibrate option to operate(√ stand for this
level has been calibrated and × stand for this level still need to be calibrate);first of all input a concentration value of standard gas
then calibrate. Target gas concentration value will set up to be the standard gas concentration value after calibration.
6.2.6 Alarm Setting
User can set the alarm limit and alarm mode in this menu, as shown in figures 34-35,there are
two alarm value setting, which are high alarm and low alarm. When user set as the low alarm
mode, it will trigger alarm when real-time concentration is lower than preset value , when user
switch to high alarm mode, it will trigger alarm when real-time concentration is higher than
preset value.
Procedures: Enter alarm settings sub-menu, Move the cursor to “Enter”,press “Ok” to select and press “Up” and “Down” to switch alarm mode, then press “Ok” to
save your modification.
