3 Terms and Definitions
3.1
In measured on the same point, the absolute value of the difference between the actual value is lower stroke return error at this point.
3.2
Output variable output according to the requirements, the difference between the measured input signal corresponding to the instrument represents the value of the set value.
4 Overview
Digital display is a standard unit of measurement for the power signal to a digital display unit instrument, mainly used for display of process parameters,
More widely used in the field.
Standard power signal main standard sub-degree temperature sensors, 4mA ~ 20mA and 1V ~ 5V DC signals, it does not exclude
He standardized the input signal power.
Digital display has a power supply 220VAC, 24VDC, the principle shown in Figure 1.

5.1 Indication error
Digital display shows the value of the maximum error should not exceed the maximum permissible error.
