(1) Sensor response time can be set according to user requirements. Faster response time means lower accuracy.
(2) The flow rate for sensor parameters is factory-set. Different settings can be made according to requirements.
(3) Baud rate = 9600 (can be set by user), data bits = 8, parity = none, stop bits = 1.
Warm-up:
- Using the preheat resistor (typically 15V; 150 mA supply) for 2-5 minutes can improve the stability of the I.R. unit at normal ambient temperature (20°C). The appropriate warm-up time depends on the specific gas detector and environmental conditions.
- It is recommended to wait at least 30 minutes after the warm-up period before making precise measurements.
