Model UT60D: OPERATING MANUAL Measurement Ranges (1) A measurement range determines the highest value the Meter can measure. Most Meter functions have more than one range. See "Accuracy Specifications." A. Selecting a Measurement Range Being in the right measurement range is important: l l If the range is too low for the input, the Meter displays to indicate an overload. If the range is too high, the Meter will not display the most accurate measurement. B.
Model UT60D: OPERATING MANUAL Measurement Ranges (2) 2. To exit the manual range mode, press and hold RANGE for over one second. The Meter returns to the autorange mode and is displayed. Note l If you manually change the measurement range after entering Hold mode, the Meter exits this mode. l Under diode, continuity and A range measurement, only manual range mode is available.
Model UT60D: OPERATING MANUAL Measurement Operation (1) A. AC & DC Voltage Measurement Warning To avoid harms to you or damages to the Meter from electric shock, please do not attempt to measure voltages higher thanDC1000V / AC750V rms, although readings may be obtained. AC Voltage Measurement (see figure 3) red black (figure 3) The AC voltage ranges are: 3.400V, 34.00V, 340.0V and 750.0V. To measure AC Voltage, connect the Meter as follows: 1. 2. 3.
Model UT60D: OPERATING MANUAL Measurement Operation (2) l When AC voltage measurement has been completed, disconnect the connection between the testing leads and the circuit under test. DC Voltage Measurement (see figure 4) red black (figure 4) The DC Voltage ranges are: 340.0mV, 3.400V, 34.00V, 340.0V and 1000V. To measure DC voltage, connect the Meter as follows: 1. 2. 3. Insert the red test lead into the HzV terminal and the black test lead into the COM terminal.
Model UT60D: OPERATING MANUAL Measurement Operation (3) B. Measuring Continuity, Diodes & Resistance 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 continuity, diodes & resistance. Testing for Continuity (see figure 5) W red black (figure 5) To test for continuity, connect the Meter as below: 1. 2. 3. Insert the red test lead into the HzV terminal and the black test lead into the COM terminal.
Model UT60D: OPERATING MANUAL Measurement Operation (4) Testing Diodes (see figure 6) W red black (figure 6) Use the diode test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semiconductor junction, then measures the voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V. To test a diode out of a circuit, connect the Meter as follows: 1. 2. 3.
Model UT60D: OPERATING MANUAL Measurement Operation (5) l l l l Connect the test leads to the proper terminals as said above to avoid error display. The LCD will display indicating open-circuit for wrong connection. The unit of diode is Volt (V), displaying the positiveconnection voltage-drop value. When diode testing has been completed, disconnect the connection between the testing leads and the circuit under test.
Model UT60D: OPERATING MANUAL Measurement Operation (6) Note l The test leads can add 0.1 to 0.2 of error to resistance measurement. To obtain precision readings in low-resistance measurement, that is the range of 340.0 , short-circuit the input terminals beforehand and record the reading obtained (called this reading as X). (X) is the additional resistance from the test lead. Then use the equation: measured resistance value (Y) - (X) = precision readings of resistance.
Model UT60D: OPERATING MANUAL Measurement Operation (7) The frequency measurement ranges are :3.4kHz, 34kHz, 340kHz, 3.4MHz, 34MHz. To measure frequency, connect the Meter as follows: 1. 2. 3. 4. Insert the red test lead into the HzV terminal and the black test lead into the COM terminal. Set the rotary switch to HzRPM; frequency measurement (Hz) is default or press Hz to select Hz measurement mode when it is under V Hz, A Hz, mA Hz or Hz A range.
Model UT60D: OPERATING MANUAL Measurement Operation (8) D. DC or AC Current Measurement (see figure 9) black red (figure 9) Warning Never attempt an in-circuit current measurement where the open-circuit voltage between the circuit and ground is greater than 250V. If the fuse burns out during measurement, the Meter may be damaged or the operator himself may be hurt. Use proper terminals, function, and range for the measurement.
Model UT60D: OPERATING MANUAL Measurement Operation (9) 3. 4. 5. 6. Set the rotary switch to A Hz, mA Hz or Hz A. Use the 10A terminal and Hz A measurement position if the current value to be tested is an unknown. The Meter defaults to DC current measurement mode. To toggle between DC and AC current measurement function, press BLUE button. AC current is displayed as an mean value (calibrated against sine wave effective value). Break the current path to be tested.
Model UT60D: OPERATING MANUAL Turning on the Display Backlight Warning In order to avoid the hazard arising from mistaken readings in insufficient light or poor vision, please use Display Backlight function. l l Press once to turn the Display Backlight on. Display Backlight will automatically shut off in about 10 seconds later. The BLUE button It uses for selecting the required measurement function when there is more than one function at one position of the rotary switch.
Model UT60D: OPERATING MANUAL Operation of Hold Mode Warning To avoid possibility of electric shock, do not use Hold mode to determine if circuits are without power. The Hold mode will not capture unstable or noisy readings. The Hold mode is applicable to all measurement functions. l Press HOLD H to enter Hold mode; the Meter beeps. l Press HOLD H again or RANGE or turn the rotary switch to exit Hold mode; the Meter beeps. l In Hold mode, is displayed.
