End of packet with checksum
As confirmation, the sensor responds with a Config -packet without any data.

Please note that this general description may be subject to changes depending on single
product execution.
Save to EEPROM
Changing the user parameter just stores them in the RAM. To save them from RAM to EEPROM use the
save command.
Command in Hex 7B 53 08 00 40 EA 00 7D
Command in ASCII { S . . @ . . }
As a confirmation, the sensor responds with a Save -packet without any data.

Please note that the EEPROM of the instrument has a limited number of writing cycles of
10,000. Under unfavorable conditions the write cycles might be limited to 10,000 only.
Starting measurements
If the sensor is in Idle -mode and does not perform measurements, it can be re-started with the
Measurement- command.
Command in Hex 7B 4D 08 00 01 EA 45 7D
Command in ASCII { M . . . . E }
As a confirmation, the sensor responds with a Measurement -packet without any data.

The sensor then starts to initialize the measurement procedure and continuously sends
measurement packets with the measured gas concentrations and other measured values,
depending on the product type. These packets also contain M as a measurement response.
