1 Scope

This standard applies to the calibration temperature calibration. Temperature Calibrator can be connected with RTD or thermocouple to measure the temperature Degree, can also simulate RTD or thermocouple output process signals to calibrate the temperature of the secondary instrument. Temperature Calibrator (hereinafter referred to as the calibrator) can be part of the multi-function calibrator. 2. References This specification references the following documents.

3 Overview

Calibrator has two functions and output measurements, temperature measuring instruments belonging to the multifunction measuring instruments. Calibrator It can be measured and simulated thermal resistance type usually Pt100, Pt500, Pt1000, Cu50, Cu100 and so on; measuring Type thermocouple simulation and usually B, S, R, K, N, E, J, T, etc; DC analog signal output from the process Current is 4mA ~ 20mA or dc voltage of 1V ~ 5V and the like. When the calibrator is set in the measurement mode, you can connect with RTD or thermocouple to measure the temperature, the equivalent of a number Word temperature indicator. Calibrator when connecting thermocouples to measure temperature, usually having a built-in reference junction temperature compensation function automatically Can, it can not directly connected with the external thermocouple cold junction compensator. Some calibrator manual switching compensation. When you set the calibrator output state can simulate a variety of thermal resistance, thermocouple temperature transmitter output and the corresponding Standard electrical signal to calibrate the temperature of the secondary instrument. Usually in the form of the numeric keypad to set the analog temperature value, can also be used Increasing or decreasing the minimum temperature in a stepwise manner to apply to analog temperature secondary instrument calibration. Calibrator thermoelectric simulation Dual output, usually a reference junction temperature automatic compensation function, the output was simulated thermocouple reference junction temperature Potential output terminal temperatures. Some calibrator manual switching compensation. RTD and thermocouple simulation, correspondence and the corresponding relationship between temperature and resistance temperature and potential are to follow GB/T 16839.2-1997, JB/T 8622-1997, JB/T 8623-1997 standards.

4 Metrological characteristics

4.1 Indication error Calibrator set in the measurement state, as the use of digital temperature indicator, which shows the difference between the input value and the standard value for the Indication error calibrator. The maximum permissible error indication will usually not exceed ± (0.01 ~ 0.6) ℃. ......
