Pressure: no pressure, fixed pressure, 1V~5V, 0~5V, 4mA~20mA, 0~l0mA, 0~20mA

Other input signals or index numbers need to be indicated at the time of ordering

Basic error: analog value is less than ±0.2%FS±1 word

Measure resolution: 1/60000, 16-bit A/D converter

Measure control cycle: 0.2 seconds per channel

1.2 Recording ·Recording capacity: 4MBit

Recording interval: 1 second to 59 minutes 59 seconds can be set arbitrarily, and cyclic or acyclic recording can be selected

Recording time: The length of the recording time is related to the recording interval. The calculation formula is as follows:

Recording hours = 24×recording interval (seconds)

It can be calculated that the shortest recording time is 24 hours and the longest time is 9 years
