Panel And Function Instruction

1.Stopwatch input terminal and stopwatch operation button:

Stopwatch input terminal: The Red terminal is START, The green terminal is STOP, The Black terminal is COM.

The buttons show "Reset", "Single / Dual", Press and hold more than 3 seconds shows (External start or external start, Default is external start), "(ON) Electric potential /Contact", "(OFF) Electric potential /Contact";

"Reset" for time reset, check if the stopwatch reset to zero before counting each time;

"Single / Dual Channel" for choosing stopwatch status (On default external dual channel), Press and hold more than 3 seconds could choose external start or internal start. Internal start means synchronization start, contacts or potential stop when internal output or removal. External single channel means OFF terminal contact or potential start/end, External dual channel means ON terminal contact or potential start/end.

"(ON) Electric potential /Contact" use for Electric potential on or Contact on.

"(OFF) Electric potential /Contact" use for Electric potential off or Contact off.

2.LCD can display the measured output voltage and current, action time and contact or potential state;

Line 1: Select Grade display output voltage and current value;

Line 2: Stopwatch measured value Select Grade display output voltage and current value; Stopwatch measure value display on the left, current status of stopwatch input terminal display on the right;

Line 3: Left:Display external start or internal start, Right: And the table state;

Line 4: Left:Display the current states are single or dual , Right: The stopwatch state.

3.Resistors and Capacitors:

(1)Resistance: 0.5Ω·10A,1Ω·5A,25Ω·2A,100Ω·0.7A,500Ω·0.3A,1000Ω·0.22A,2500Ω·0.14A; Obtain the resistance by select different terminal; accurately adjust the required value of voltage and current by string into the voltage and current output grade;

(2)Capacitor: 10uF/AC450V.

4.Measure selection indicate: 0~100A,0~40A,0~10A,0~250V,0~300V,external input; Led Indicator Lights Up shows output value in LCD.

5.Split/join the auxiliary contact; the contact synchronize with 10 point "ON/ OFF" button.

6.AC voltage and current output terminal: 0~10A·90V,0~40A·25V,0~100A·10V,0~250V·3A,The black terminal is COM.

7.DC current output terminal: 0~300V·3A,the terminal is independent output Red + Black -.

8.External input VOLTMETER & AMMETER; display measure value by select external input grade of "Output selection"button.

9.Current and voltage output Knob: Adjust output value by match "ON/ OFF" of 10 contact button.

10."Output Selection" and "ON/ OFF" button: "Output Selection" button is only used in the removal state match measure selection indication; "ON/ OFF" button is used for controlling output and removal, Top left LED light up when output, lights out when removal.

11.Auxiliary DC voltage power: can finely adjust voltage value independently, Select grade 0~110V/ 110~220V by control "ON/ OFF" button.

12.Computer interface: for debugging device, downloading programs and updating software.

13.Power switch: Device power switch.

14.Power outlet.

15.Grounding terminal.

16.Contrast adjustment: adjust the brightness of LCD.

Caution

Grounding: The device must be reliably grounded during operation to ensure safety.

Display Adjustment: If the display appears too dark or completely black, adjust the "Contrast Adjustment" control to achieve optimal visibility.

Measurement Selection: The measurement selection button is disabled once current output begins. Ensure all measurement parameters are selected before initiating current output.
