*1. The cable connected to the input terminal should be the cable or the shielded twisted pair cable which can
be connected to an Ni100/Ni1000/Pt100/Pt1000 sensor, and should be kept separate from other power
cables and cables which generate noise. Please use a three-wire temperature sensor. If users want to use
a two-wire temperature sensor, O
n + and I n + must be short-circuited, and O n - and I n - must be short-
circuited. ( n is in the range of 0 to 7.)
*2. If users want to measure
resistance in the range of 0 Ω to 300 Ω, they can use a two
-wire or three-wire
sensor instead of a four-wire sensor.
*3. User need to select an appropriate sensor. If an Ni100 temperature sensor, a Pt100 temperature sensor,
or a resistance sensor is used, the internal excitation current is
471.5 μ
A. If an Ni1000 temperature sensor,
or a Pt1000 temperature sensor is
used, the internal excitation current is 204.8 μA.

Note: use cables with the same length (less than 200 m) and use terminal resistors of less than 20 ohm.
