VII: Measurement operation instructions Figure 1 1. Measursment of DC voltage ( see Figure 1) 1. Insert the black test lead into the COM socket, the red test lead into the V socket. 2, Switch the function knob to “V” position. And then connect test leads with the power supply (for measuring open circuit voltage} or the load (for measuring load voltage drop), the polarity will be displayed on the screen. A Note: ® Do not Input any voltage higher than 1000V.
Figure 2 2.Measurement of AC voltage { ses Figure 2) 1. Insert the black test lead into the COM socket, the red test lead into the V socket. 2. Switch the function knob to “V™ position. Connect test leads with the power supply (for measuring open circuit voltage) or the load (for measuring load voltage drop). A Note: © Do not input any voltage that is higher than 750V. Otherwise there is a risk that the instrument might get damaged. When measuring high voltage, pay attention to avoid electric shocked.
Figure 3 3.Measurement of AC /DC current {see Figure 3) 1. Insert the black test lead into the COM socket, the red test lead into the “yA” or “A” socket. 2. Switch the function knob to “A-" or “A~" position, then connect the Instrument In serfs with the cultural to be tested. A Note: ® Before measuring current, the power supply of the circuit should be switched off, and discharge all capacitors.
Figure 4 4.Measurement of Resistance {see Figure 4) 1. Insert the black test lead into the COM socket, the red test lead into the © socket. 2. Switch the function knob to Q position, then connect test leads with the resistance to be measured. A Note: ‘® Before measuring current, the power supply of the circuit should be switched off, and get the residual charge stored in the high voltage capacitor fully discharged. ® In low resistance measurement, the test leads will bring about 0.10 to 0.
Figure 5 5. Measurement of capacitance (ses Figure 5) 1. Insert the black test lead Into the COM socket, the red test lead Into the 46 socket. 2.
