The GasAlertMax XT II is a personal safety device used to warn users when hazardous gas levels exceed user-set alarm setpoints. The instrument features visual, audible, and vibratory alarms for various conditions such as low, high, TWA, STEL, multiple gases, and out-of-limit (OL) readings.
The manual covers essential operational procedures including startup and shutdown sequences using the C button. It details how to perform sensor zeroing and calibration, which must be done in a safe area with 20.9% oxygen content at least every 180 days. Safety warnings regarding battery handling, sensor exposure to contaminants like lead compounds or silicones, and proper use of pump accessories are also included. This manual is written in Chinese.
The sensor must be calibrated at least every 180 days (6 months).
The maximum length for the calibration hose is 3 feet (1 meter).
This may indicate a gas concentration exceeding the scale upper limit, which could be dangerous.
