How to use a VOC gas detector for data collection
As is well known, VOC gas detector is an instrument 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, it has very high requirements for data collection. If the data collection is incorrect, it is likely to directly affect the effectiveness of subsequent use. Do you know how to collect data from VOC gas detectors?
Data collection of VOC gas detector:
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. The instrument saves gas concentration data, user ID, on-site ID, serial number, last calibration date, alarm limit value, and other information at the end of each data collection cycle (data collection has been enabled). 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: The 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) Snapshot: Collect data in the snapshot sampling state (press the mode key to activate single event data capture).
2. Data collection events:
When 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 parameter settings are changed, or data collection is interrupted, a new test time is generated and relevant information is saved. The duration of each event shall not exceed 24 hours, or the data collection volume shall not exceed 28800 points. If the same event continues for more than 24 hours, a new event will be automatically generated. The event start time, 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 numbers, dates, gas concentrations, and other relevant information.
