IV.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.

4
“(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

5
0~110V/ 110~220V by control “ON/ OFF” button.
12.Computer interface: for debugging device, downloading programs and updating
software.

V.Usage Method
1.Voltage and current
Power on, select output current terminal or voltage terminal, Press “Output
selection”terminal, press “ON/ OFF”button,Device shows simulation failure state, you can
adjust knob to control AC/DC voltage and current output.
2.Auxiliary Output DC voltage and current
First, cycles the potentiometer to zero, connect the output line, select the required
voltage value(0V or 110~220V),then press output button, adjust potentiometer ,you will
find voltage and current output; You only need press “Output Selection” to external input,
and connect output to external input voltage and current terminal, or to external Voltmeter
and Ammter.
3.Resistance ( single resistor 50w ), capacitors usage
First, disconnect the U - shaped short tab on the Rx, then select the appropriate value
resistance or capacitance in series, and connect as following three figures.
Figure 5-1 String into a resistor 500 ohm/50W

Figure 5-2 String into seven 50W resistors
Figure 5-3 String into capacitors
4.Stopwatch
（1）Input signal
Default contact converts On to Off or Off to On.
With 5V-250V positive DC contact converts On to Off or Off to On.
（2）Signal input way
Whether single or dual input, the measurement is, the two input terminals generally
should be directly connected to the two contact of switch when measuring not charged or
charged contact switch signal, Figures 1 (1) - (4) are shown
Note: Regardless of the figure 1 (3) - (4) connection way, the black terminal of stopwatch
should always connect to LOW level.
（3）Application examples
Measure action time and feedback time:
Test connection as shown in Figure 2, set internal dual channel of “single / dual” button.
①Measure action time: Press ON button, adjust the required voltage/current value,
Press OFF, Reset stopwatch, then press ON, stopwatch LCD will display the momentary
lag from power on moment to connect normally (or normally closed contact to disconnect)
of the relay coil.

7
②Measure feedback time: after measuring action time, reset stopwatch, then press OFF,
LCD will display the momentary lag from power off to the normally open contact and
disconnected (or normally closed contact and close moment), of the relay coil.
VI.Caution
1. Device should be reliable grounding when operation to keep safety;
2. Please adjust the "contrast adjustment", if the display shows dark or black;
3. The measuring selection button is invalid after the current outputting.
