PERFORMANCE in percentage of span

Setpoint accuracy (trip point accuracy):

Accuracy in Table 1 + Cold junction compensation error

Cold junction compensation error:

±3°C at 25 ±10°C

±5.4°F at 77 ±18°F

Temp. coefficient: ±0.01 %/°C (±0.006 %/°F) of max. span

Response time: ≤ 0.5 sec. (0 – 100 % at 90 % setpoint)

Burnout response time: ≤ 1 sec.

Line voltage effect: ±0.1 % over voltage range

Insulation resistance: ≥ 100 MΩ with 500 V DC

Dielectric strength: 2000 V AC @1 minute (input to output

CALCULATION EXAMPLES OF SETPOINT ACCURACY

[Example] K thermocouple, 0 – 1000°C

Absolute value accuracy (Table 1): 0.25°C

CJC error (3°C) added: 3.25°C

Setpoint accuracy = 3.25°C ÷ 1000°C × 100 = 0.33 %
