The error is ±1°C of a Pt100/Pt1000/Ni100/Ni1000 sensor's temperature.
The error is ±0.1% of a resistance in the range of 0 Ω to 300 Ω.

Quick mode:
Four-wire/Two-wire configuration: 20 ms/channel
Three-wire configuration: 200 ms/channel

General mode: A conversion time will be gotten after the conversion time of
the two channels in a group is added up.
Four-wire/Two-wire configuration: 200 ms/channel
Three-wire configuration: 400 ms/channel
An analog circuit is isolated from a digital circuit by a digital integrated circuit,
and the analog channels are isolated from one another by optocouplers.
Isolation between a digital circuit and a ground: 500 VDC
Isolation between an analog circuit and a ground: 500 VDC
Isolation between an analog circuit and a digital circuit: 500 VDC
Isolation between two group circuits: 500 VDC
Isolation between the 24 VDC and a ground: 500 VDC
