How to use a VOC gas monitor for the collection of data
As is well known, VOC gas detectors are used to continuously measure toxic and harmful organic gases in hazardous or industrial environments, especially suitable for personal safety protection and on-site VOC detection. Therefore, they have very high requirements for data collection. If the data collection is incorrect, it is very likely to directly affect the effectiveness of subsequent use. So how does a VOC gas detector collect data?
1. Data collection mode:
When the VOC gas detector is collecting data, the instrument displays a disk symbol, indicating that data collection is in progress. At the end of each data collection cycle (when data collection is enabled), the instrument saves gas concentration data, user ID, field ID, serial number, last calibration date, alarm limits, and other information. Even if the instrument is turned off, all data is saved in the instrument's memory and will not be lost. Can transfer data to a computer.
There are three data acquisition modes for VOC gas detector equipment:
(1) Automatic: default mode. When the instrument starts sampling, it automatically collects detection data.
(2) Manual: Data collection can only be carried out after manually activating the data collection function.
(3) Snapshots: Collect data in snapshot sampling mode (activate single event data capture by pressing the mode key).
2. Data collection events:
After data collection is enabled, the detected data is saved. These data are saved in the form of groups or events. Every time the instrument is turned on, or there is a parameter change or interruption in data collection, a new test time is generated and relevant information is saved. The duration of each event shall not exceed 24 hours, or the amount of data collected shall not exceed 28800 points. If the same event lasts for more than 24 hours, a new event will be automatically generated. The start time of the event, user ID, on-site ID, gas name, serial number, last calibration date, alarm limit value, and other information will be automatically recorded and saved.
3. Data collection samples:
When recording data collection events, the instrument saves the abbreviated form of data. When data is transmitted to a computer, it can be arranged through software to present sample size, date, gas concentration, and other related information.
