How do I set the alarm setpoint on a VOC detector?
Alarm point setting: Conventional factories only set A1 alarm value and A2 alarm value; TWA alarm value, S alarm value, and low concentration alarm value can be set separately according to user requirements.
1. A1 alarm value: also known as the first alarm value, when the instrument detects a gas concentration higher than the A1 set value, the instrument will simultaneously issue an audible and visual alarm and a vibration alarm. The alarm value and type can be customized.
2. A2 alarm value: also known as secondary alarm value, when the instrument detects a gas concentration higher than the A2 set value, the instrument will simultaneously emit sound and light alarms and vibration alarms. The alarm value and type can be customized.
3. Low concentration alarm value: When the instrument detects that the gas concentration is lower than the set value, the instrument will simultaneously emit sound and light and vibration alarms, and can customize the alarm value and type.
4. TWA alarm value: The instrument records measurement data every 10 minutes and 48 times within 8 hours. When the average value of these data is higher than the set value of the TWA alarm value, the instrument will simultaneously issue an audible and visual alarm, and can customize the alarm value and type.
5. Alarm value: The instrument records measurement data at regular intervals, recording 15 data points within 15 minutes. When the average value of the 15 data points is higher than the set value of the S alarm value, the instrument simultaneously emits an audible and visual alarm. The alarm value and type can be customized.
