Voltage And Current Signal Generator
1. Technical Indicators
1.1 three power supply modes ,using the mobile phone charger or external 24V can charge/work;
1.1.1 External wiring terminal power supply DC15-30V 1W(without charging)/4W(charging);
1.1.2 External MicroUSB-5V current 0.2a (no charge)/0.8A(charge);
1.1.3 (Optional) The built-in 3.7V lithium battery(1000mah), the maximum charging current is 0.6A, Generally, it takes more than 4 hours to fully charge. It can be used for 1-5 hours;
1.2 The voltage output is adjustable ± 10V, Error<0.05V after calibration, and the driving current <20mA
1.3 The current output is adjustable 0-22ma,Error<0.05mA after calibration, and the sampling resistance is <500¥Ø;
1.4 working environment: 0-40 ¡É, relative humidity < 80%£»
1.5 Size (cm)£ºShell=100x60x20 ,The plug protruding 9cm,The knobprotruding 15cm

2.1 Voltage signal output£º5-AVO 6-GND
2.2 Common active mode of current output£ºOur output 4-AIO 6-GND corresponds to PLC I + I -!
2.3 Current passive mode£ºThe PIN 3-AI+ is externally connected to 24V+, and then output from 4-AIO to control the external 24V current.Our meter is equivalent to an adjustable resistance;Therefore, it is called passive mode.

3.2 Switching - Adjust the display V or I, press the "MODE" key to switch and adjust the display V or I MODE
The indicator light shows what state it is in and what mode the system operation is in;
The original output will continue to output After switching, but not in the adjustment status;
Turn on the battery switch to check the battery status and quantity

4 current problem detection: the possibility of the current not output is very small,you can measured the voltage of 4-AIO 6-GND with a multimeter, if it is >20V, than current file of your multimeter is broken or gear is wrong, because there are voltage must be current, try change a multimeter, multimeter current file inside a fuse is easy to burn;
5 Please Read This Manual Carefully Before Wiring, Turn Off The Power And Then Connect;
