UT205E/UT206B/UT207B/UT208B User Manual 7. Resistance Measurement (Picture 9) UT205E/UT206B/UT207B/UT208B User Manual When measuring resistance above 1MΩ, it is normal to take a few seconds to stablize reading. Use caution when working with voltage above AC 30Vrms, 42Vpeak or DC 60V. Those voltages may pose shock hazard. After completing the measurement, disconnect the test leads from the circuit under test. 8.
UT205E/UT206B/UT207B/UT208B User Manual 3) Connect the red probe with the diode anode, and black with the diode cathode. 4) Read the approximate forward voltage of the diode on the display. For silicon PN junction, the normal value is generally about 500~800 mV. Note: If the diode is open or its polarity is reversed, the LCD will display “OL”. Before measuring the diode online, switch off the power supply of the circuit, and fully discharge all capacitors.
UT205E/UT206B/UT207B/UT208B User Manual 1) Insert the red test lead into the , or jack, and black into the COM jack. 2) Turn the function dial to the Hz% position, and connect the test leads with both ends of the measured signal source in parallel. 3) Short press the SELECT button to switch to frequency/duty ratio measurement. Note: Do not input voltage higher than 30Vrms to avoid personal injury. After completing the measurement, disconnect the test leads from the circuit under test. 12.
UT205E/UT206B/UT207B/UT208B User Manual 1) Turn the function dial to the NCV position, and bring the NCV sensor close to the wire under test. 2) If there is AC voltage or electromagnetic field in the space, the LCD will display the sensing intensity from weak to strong by “—”. At the same time, the buzzer will beep intermittently and the LED indicator light will be on. When no voltage is sensed, the LCD displays “EF”. 14.
