Max. non-linearity error for

thermocouples (TC),

resistors (PT100) and

thermistors (PTC, NTC).

The error is calculated as

deviation from theoretical

value and is expressed as

percentage of full scale

(in °C).

S, R range 0...1750°C; error < 0.2% f.s. (t > 300°C) / for other

range; error < 0.5% f.s.

error < 0.2% f.s. (t > 200°C)

range 0...2300; error < 0.2% f.s. / for other range;

error < 0.5% f.s.

NTC error < 0.5% f.s.

Tc: J, K, E, N, L error < 0,2% f.s.

JPT100 and PTC error < 0,2% f.s.

PT100 scale -200...850°C

Precision better than 0,2% f.s. at 25°C

In range 0...50°C:

• Precision better than 0,2% f.s. in range -200...400°C

• Precision better than 0,4% f.s. in range +400...850°C
