Specifications
Measurement range
–20°C to +60°C
Accuracy
±0.3°C (typical value), in combination with the 2553A
Excitation current
Approx. 1 mA
Withstand voltage
100 VAC for 1 minute between the 257875 measurement section and the 2553A case
(Withstand voltage when the sensor is connected to the 2553A’s external RJ sensor input terminal)

Approx. 1.95 m
• Only connect the RJ sensor 257875 to the 2553A or other designated instruments.
• If the RJ sensor 257875 is connected directly to the input terminals of the measuring instrument to be calibrated and the
temperature of the terminals is different from the ambient temperature, the temperature imbalance will cause the temperature
of the terminals to change. This may prevent accurate reference junction compensation.
