Within ±1% FS (T)

Calibration

100 to 1700°C in every 100°C steps
(Varies with thermocouple models.)

Accuracy: Within ±0.5% FS

Sensitivity Adjustment

Sensitivity is set in combination with a 2-digit INPUT switch and a 3-digit OUTPUT switch.

OUTPUT switch range: 1.00 to 5.00 V in 0.01-V step
INPUT switch range: 100 to 1700°C in 100°C step

Fine Sensitivity Adjustment

×0.4 to ×1

Noise

30 mV_p-p or less (Input short)

Stability

Temperature
Zero point: Within ±0.05% FS/°C
Sensitivity: Within ±0.05%/°C

Time
Zero point: Within ±0.5% FS/8 h
Sensitivity: Within ±0.5%/8 h

(When type K, 1300℃ input and 5 V output.
Zero point is measured by the input of voltage with response of 0℃, sensitivity is measured by the input of voltage with response of 1300℃.)

Output
