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.

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.
① Measure 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.
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.
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.
