YJ108D Digital Source TableDetailed product description：

Overview
YJ108D digital source meter is an instrument that combines precision measurement or output of DC voltage. Due to the application of advanced microcomputer and analog-to-digital/digital to analog conversion technology, the use of high-precision operational amplifiers, and advanced negative feedback technology, this instrument is endowed with a measurement function of 6 1/2 reading bits and a voltage resolution of 0.1 μ V, and an output function of 5 reading bits and a voltage resolution of 1 μ V, all with high accuracy.
The instrument is equipped with an RS232 serial interface, which can be connected to a computer to achieve the purpose of programmable instrument functions, range, and reading output.
The instrument uses an 8-bit LED digital tube to display measurement readings and output readings, which are clear and eye-catching.  

Main technical indicators

	range	resolution	basic error
measurement function	0.2V	0.1μV	±（0.003%RD+0.0025%FS）
	2V	1μV	±（0.003%RD+0.0006%FS）
	20V	10μV
	200V	100μV
Output function	0.1V	1μV	±（0.01%RD+0.005%FS+20μV）
	1V	10μV
	10V	100μV

When outputting voltage, the maximum output current should not be less than 20mA
