7. Key Functions 1) 72-13430: SEL/REL: press this key to switch between AC and DC modes for mV , I and REL positions. HOLD/ : Press to enter or exit data hold mode. Long press over 2 seconds to turn on/off backlight. - Page 5 Note: • Before measuring PN junction, switch off the power supply to the circuit, and fully discharge all capacitors 5. Capacitance measurement (only for 72-13430, see Figure 2a) 1) Switch the dial to capacitance test. 2) Insert the black test lead into the COM jack, the red test lead into the “VΩmA” jack. Connect test leads with the capacitor in parallel 3) When there is no input, the device displays a fixed value (intrinsic capacitance).
- Page 6 • If the tested current is over 10A, each measurement time should be less than 10 seconds and the next test should be after 15 minutes. 7. AC measurement (only for 72-13430, see Figure 3) Similar to DC Measurement. Please refer to Section 6 “DC measurement (see Figure 3)”...

10. NCV measurement (only for 72-13440, see Figure 6) 1) Switch the dial to NCV position 2) Place the device near the measured object. “-” symbol indicates the intensity of the electric field. More “-” and the higher the buzzer frequency, the higher the electric field intensity. 3) Intensity of electric field. - Page 8 Part Number Resolution Accuracy 200mV 0.1mV ±(0.7% +3) 2000mV ±(0.5% +2) 20.00V 72-13430/13435/13440 0.01V ±(0.7% +3) 200.0V 0.1V ±(0.7% +3) 250V ±(0.7% +3) • Input impedance: about 10MΩ • Results might be unstable at mV range when no load is connected. The value becomes stable once the load is connected.
