Model UT601: OPERATING MANUAL Measurement Operation is not on, l Make sure the Low Battery Display otherwise false readings may be provided. symbol, before carrying l Pay extra attention to the measurement, which is located besides the input terminals of the Meter. A. Measuring Resistance (see figure 3) (figure 3) Warning To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before measuring resistance.
Model UT601: OPERATING MANUAL Note l When measuring at 20Ω and 200Ω range, the test clips can add 0.1 to 0.3Ω error to resistance. To obtain precise readings in these low-resistance measurement, that is the range 20Ω and 200Ω, short circuit the input terminals beforehand and record the reading obtained (called this reading as X). (X) is the additional resistance from the test clips. Then use the equation: measured resistance value (Y) – (X) = precision readings of resistance.
Model UT601: OPERATING MANUAL B. Capacitance Measurement (see figure 4) (figure 4) Warning To avoid damage to the Meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the DC Voltage function to confirm that the capacitor is discharged. The Meter’s capacitance ranges are:200pF, 2nF, 20nF, 200nF, 2µF, 20µF, 200µF, 2mF and 20mF. To measure capacitance, connect the Meter as follows: 1.
Model UT601: OPERATING MANUAL 4. When measuring small value capacitor, that is 200pF, 2nF and 20nF, first open circuit the test clips or the Small Value Capacitance Jack, then turn the Capacitance Zero Adjustment Switch to adjust zero. 5. The measured value shows on the display. Note l Do not short the test clips to avoid the consumption of battery.
Model UT601: OPERATING MANUAL C. Diode and Continuity Test (see figure 5) red (figure 5) Warning To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before measuring diodes and continuity. Testing Diodes Use the diode test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semiconductor junction, and then measures the voltage drop across the junction.
Model UT601: OPERATING MANUAL Note l In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to 0.8V; however, the reverse voltage drop reading can vary depending on the resistance of other pathways between the probe tips. l Connect the test clips to the proper terminals as said above to avoid error display. The LCD will display “1” indicating open-circuit for wrong connection. The unit of diode is Volt (V), displaying the positive-connection voltage-drop value.
Model UT601: OPERATING MANUAL D. Transistor hFE Measurement (see figure 6) NPN PNP hFE (figure 6) To measure transistor, set up the Meter as follows: 1. Check that the transistor is PNP or NPN type. 2. Insert the transistor to be measured to the corresponding Transistor Jack. 3. The Meter displays the tested transistor’s nearest value.
