Voltage signal output：5-AVO  6-GND
Common active mode of current output：Our output 4-AIO6-GND corresponds to PLC I + I -!
Current passive mode：The 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.



Usage：


	Operation panel and operation instructions







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

Hold the "MODE" key for 1 second and the digital tube flashes for 5 seconds to display the battery voltage;



Digital adjustment and parameter setting：

（Forewarned：Push Down The Knob Is “OK”,Clockwise Rotation The Knob One Pulse Is” + ”, Anticlockwise Rotation The Knob One Pulse Is” - ”）

Short Press “OK” To Save The Output Value,Digital Tube Display "..." After loosening, Saved Successfully, The Output Value Is This Saved Value After The Next Boot; When We Debug The Device, We Need To Adjust The Output Value Randomly, As Long As The Knob Is Not Pressed, It Will Still Be The Saved Value After Rebooting;
Hold The “OK” For 2 Seconds To Enter The Setting State.,Display”F001”(Parameter Number 001);
Turn the knob to change the parameter number, You need to enter a password when enter F002 or F100：

	F001->F002enter a password“+ - - +（Turn the knob）”,Then press the knob to enter;
	F001->F100enter a password“+ - + -（Turn the knob）”,Then press the knob to enter;


Press "Ok" to enter the setting of corresponding parameter value, and turn the knob to modify parameters；
Press "Ok" to save the parameter, exit the parameter setting, and display the next parameter number (after setting the F001 value without entering the password, the normal operation screen will enter);
Rotate the knob directly to the last parameter number, press the "OK" key, and the setting is completed;
If no operation on the parameter setting screen exceeds 10s, it will exit the setting state;

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;
Please Read This Manual Carefully Before Wiring,Turn Off The Power And Then Connect;
