Storage capacity: Internal Flash memory capacity 64M Byte
Recording interval: 1, 2, 4, 6, 15, 30, 60, 120, 240 seconds, nine gears to choose from.
Storage length: 24 days (when the interval is 1 second) - 5825 days (when the interval is 240 seconds)
Calculation formula: record time (days) =
(Note: Calculation of the number of channels: The program divides the number of channels into five gears: 4, 8, 16, 32, and 64. When the number of instrument channels falls between the two gears, the larger number is used as the calculated channel number. For example: instrument The number of channels is 12, and the number of channels in the formula is calculated as 16)
Use environment: Ambient temperature: -10～50℃; Relative humidity: 10～90%RH (no condensation); Avoid strong corrosive gas. (! Note: If the on-site environment is bad, special instructions must be made when ordering)
