For the temperature measurement (RTD), high resolution of 0.01°C (0.01°F) can be obtained. In DC V and resistance measurement, the resolution of 100 nV and 100 μohm can be obtained with high stability. (see below)

In addition, the high-speed sampling rate of up to 10 ms are available for the study of biometeorology/medical development of electronic components where the rapid and precise temperature measurement are required.

4 types of RTD's (2-wire/3-wire/4-wire) and 12 types of TC's are available for use in a wide range of applications. In addition, DC V and Resistance (2-wire/4-wire) measuring functions are also available in a single instrument.
TC: 12 types (R, S, B, K, E, J, T, L, U, N, W and KPvsAu7Fe) RTD: 4 types (Pt100, JPt100, Pt1000 and J263*B)

Compensation accuracy (±0.2°C) Input terminals are provided on both front and rear panels, and an input site is switch selectable. The rear panel input terminal has an isothermal structure, and it is provided with windbreak cover of one-touch type.

The 7563 uses a YOKOGAWA-original transistor temperature sensor in the reference junction compensation circuit. A compensation accuracy of ±0.2°C (±0.4°C) is realized together with the isothermal structure of the input terminal.

Adjustment function of R₀ expands the 7563's input ranges. As adjustment range of this function covers 0 to 2,000 ohm with 0.001 ohm resolution, the combination of this function and three ranges for Pt RTD sensor offers the customer to use almost all types of RTD sensors available in the world.

1. External RJC with adjustable reference function temperature.
   This function means that the user can use any type of reference temperature, such as H2O (t), He (v), O2 (t), Hg (t), Ga (m), Sn (f), Au (f), etc. Adjustment range covers all temperature ranges of 12 thermocouples with 0.1°C (0.1°C) resolution.
2. Remote RJC utilizing Pt100 sensor (Program Mode).
   In this mode, Pt100 sensor measures the temperature of external input terminal, and the 7563 compensates the reference junction temperature of the thermocouple connected to the external input terminal.

IC memory card expands the applicability. It is possible to save up to 8,000 measured data as a buffer memory. It also allows you to save the panel setting conditions and read them automatically at power ON (AUTO LOAD). In addition, measuring parameters can be programmed in up to 20 steps into the IC memory card.

The 7563 incorporates a bidirectional communication function which supports the system use. Not only the measured data output, but also all the functions executed by panel key operation excluding only the power supply ON/OFF operation can be controlled from a host computer by a powerful set of commands.

In addition to the noise elimination by moving average function and offset compensation (NULL), a scaling function and comparator function are also available. (Example) When TC is calibrated at a reference temperature (Ts), the correction for measured value (Tx) can easily be obtained by using the scaling function. (Figure 5) Scaling function: (X-A)/B, provided that, A = 0, B = Tx/Ts

Calibration of DC V and W can be executed by simple panel key operation or via communication interfaces. Calibration values for temperature measurement ranges are automatically calculated by only giving reference inputs for DC V and W ranges.
