Important: user should make this setting before following operations.
B. In “Common Calibration” interface, short press “▲” or “▼” to select gas, long press
“OK” button, the background of selected gas will turn red, connect calibration gas
and after the value is stable, long press “OK” button to complete this operation with
display of “Set OK”. Short press “ ” to exit.
Notice:
a. Before calibration, activate this device for at least 6 minutes to allow it run stably
b. When the device is alarming for low power, stop calibration and charge it right away
c. Calibration gas must be standard gas used for calibration purpose
d. Zero sensors firstly before calibration
e. Make sure gas flow is stable before connecting calibration gas, calibration gas flow for CH4,
CO, O2 is 200ml/min, 300ml/min for H2S.
f. Suggested calibration gases are as following:
CH4 1.00%vol, CO 500ppm, H2S 50ppm, oxygen can be calibrated in fresh air
11. In setting interface, short press “ ▲” or “ ▼” to select among “CH4”, “LEL”, “PPM”,
“MG/m³”, “Allow Calibration”, “ √” means item is selected. Long press “OK” button to
select and confirm. Short press “ ” to exit.
Important: User can’t enter calibration interface without choosing “Allow Calibration”
