Model UT60A: OPERATING MANUAL Safety Information This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage category (CAT. III 1000V, CAT. IV 600V) and double insulation. CAT. III: Distribution level, fixed installation, with smaller transient overvoltages than CAT. IV CAT IV:Primary supply level, overhead lines, cable systems etc.
Model UT60A: OPERATING MANUAL Rules For Safe Operation (1) Warning To avoid possible electric shock or personal injury, and to avoid possible damage to the Meter or to the equipment under test, adhere to the following rules: Before using the Meter inspect the case. Do not use the Meter if it is damaged or the case (or part of the case) is removed.
Model UT60A: OPERATING MANUAL Rules For Safe Operation (2) Before measuring current, check the Meter's fuses and turn off power to the circuit before connecting the Meter to the circuit. Replace the battery as soon as the battery indicator appears. With a low battery, the Meter might produce false readings that can lead to electric shock and personal injury.

Model UT60A: 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: If the range is too low for the input, the Meter displays to indicate an overload.
Model UT60A: OPERATING MANUAL Measurement Ranges (2) To enter and exit the manual range mode: Press RANGE. The Meter enters the manual range mode and turns off. Each presses of RANGE increments the range. When the highest range is reached, the Meter wraps to the lowest range.
Model UT60A: 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 than 1000V / 750V rms although readings may be obtained.
Model UT60A: OPERATING MANUAL Measurement Operation (2) Note In each range, the Meter has an input impedance of 10M . This loading effect can cause measurement errors in high impedance circuits. If the circuit impedance is less than or equal to 10k , the error is negligible (0.1% or less).
Model UT60A: OPERATING MANUAL Measurement Operation (3) Note In each range, the Meter has an input impedance of 10M . This loading effect can cause measurement errors in high impedance circuits. If the circuit impedance is less than or equal to 10k , the error is negligible (0.1% or less).
Model UT60A: OPERATING MANUAL Measurement Operation (4) Note The LCD displays indicating the circuit being tested is open. When continuity testing has been completed, disconnect the connection between the testing leads and the circuit under test. Testing Diodes (see figure 6)
Model UT60A: OPERATING MANUAL Measurement Operation (5) Note 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.
Model UT60A: OPERATING MANUAL Measurement Operation (6) Connect the test leads across with the object being measured. The measured value shows on the display. Note 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 400.0 , short-circuit the input terminals...
Model UT60A: OPERATING MANUAL Measurement Operation (7) 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.
Model UT60A: OPERATING MANUAL Measurement Operation (8) D. Frequency & Duty Cycle Measurement (see figure 9) Select Hz Test Black (figure 9) Frequency Measurement The measurement ranges are from 10Hz to 40MHz. To measure frequency, connect the Meter as follows: Insert the red test lead into the HzV terminal and the black test lead into the COM terminal.
Model UT60A: OPERATING MANUAL Measurement Operation (9) Range Signal Frequency Requirement Range 200mV 200 A 10Hz~1kHz 20mA When Hz measurement has been completed, disconnect the connection between the testing leads and the circuit under test. Duty Cycle Measurement The duty cycle measurement range is 0.1% ~ 99.9%.
Model UT60A: OPERATING MANUAL Measurement Operation (10) E. DC or AC Current Measurement (see figure 10) Select Black Hz or (figure 10) Warning Never attempt an in-circuit current measurement where the open-circuit voltage between the circuit and ground is greater than 250V.
Model UT60A: OPERATING MANUAL Measurement Operation (11) 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).
Model UT60A: OPERATING MANUAL The POWER button This is a self-lock switch use to turn on or off the power of the Meter. 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 UT60A: 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.
