How to set the transformation ratio of the multi-function digital display?

The multi-function digital display is a multi-functional intelligent instrument with programmable measurement, display, digital communication, power pulse transmission and output, etc. It can complete electricity measurement, electric energy measurement, data display, collection and transmission. Multifunctional power instruments are widely used in substation automation, distribution automation, smart buildings and internal enterprise power measurement, management and evaluation. The measurement accuracy is 0.5.

A data display is just a display instrument that reflects data. For displaying data within an accuracy range based on actual measurements, the error you are referring to should not be caused by the data display. You should focus on the primary component of measurement, such as a pressure transmitter. If the data display you mean is a digital pressure gauge, if the fluctuation of the measured data is outside the error range, you can use a standard pressure source to calibrate the gauge, and note that the accuracy of the pressure source is less than that of the gauge.

Installation method of multi-function digital display meter:

1). On the fixed power distribution cabinet, choose a suitable place to open a mounting hole with the opening size.

2). Take out the instrument, loosen the positioning screw, and remove the fixing clip.

3). Insert the instrument installation into the instrument hole of the distribution cabinet.

4). Insert the fixing clip of the meter and fix the positioning screw.

Note: L-N is the auxiliary power supply, please connect correctly according to the wiring diagram of the instrument case!
