Due to the increasing integration of TVs nowadays,the voltage requirements of TVs for machines are getting higher and higher.For example, small-signal power supply of 1.25V to 1.28V (only 0.03V high) may cause a crash,so The requirements for multimeters are getting higher and higher.In order for everyone to take less detours during maintenance,the AD584 benchmark was specially made to correct the commonly used three and a half multimeters,as suggested by many divisions in the maintenance group.
The input voltage can be 12V-24V (for players with high accuracy requirements, it can be powered by 23A 12V battery). The input and output positions are marked on the board. Changing the position of the jumper cap can get different output voltages.
The output voltage is divided into four levels: 2.5V, 5.0V, 7.5V, 10.0V
The resistance reference uses 1 / 10,000 precision resistors of 100 ohms, 1K, 10K and 100K.
The following is a real-time measurement chart of the 5238-digit multimeter with a daily setting of 3238. The measured data of each board will be written on the back of the board.
