DC Current Measurement (see figure 4) ( figure 4) Warning Never attempt an in-circuit current measurement where the open circuit voltage between terminals and ground is greater than 60V DC or 30V rms. 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 UT60H: OPERATING MANUAL Measurement Operation(4) Note l If the value to be measured is unknown, use the maximum measurement position and reduce the range step by step until a satisfactory reading is obtained. l When the measured current is 5A, continuous measurement is allowed. l When the measured current is between 5A-10A, continuous measurement 10 seconds and interval more than 15 minutes.
Model UT60H: OPERATING MANUAL Measurement Operation(5) Note l If the value to be measured is unknown, use the maximum measurement position and reduce the range step by step until a satisfactory reading is obtained. l When the measured current is 5A, continuous measurement is allowed. l When the measured current is between 5A-10A, continuous measurement 10 seconds and interval more than 15 minutes.
Model UT60H: OPERATING MANUAL Measurement Operation(6) E. Measuring Resistance (see figure 5) (figure 5) Warning To avoid harms to you, please do not attempt to input voltage higher than 60V DC or 30V rms AC. 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. The resistance ranges are:400Ω, 4kΩ, 40kΩ,400kΩ, 4MΩand 40MΩ. To measure resistance, connect the Meter as follows: 1.

Model UT60H: OPERATING MANUAL Measurement Operation(8) F. Testing for Continuity (see figure 6) (figure 6) Warning To avoid harms to you, please do not attempt to input voltage higher than 60V DC or 30V rms AC. 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. Note l Open circuit voltage around –1.2V and range is 400Ω measurement range.
Model UT60H: OPERATING MANUAL Measurement Operation(9) G. Testing Diodes (see figure 7) ( figure 7) Warning To avoid harms to you, please do not attempt to input voltages higher than 60V DC or 30V rms AC. To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before testing diodes. Use the diode test to check diodes, transistors, and other semiconductor devices.
Model UT60H: OPERATING MANUAL Measurement Operation(10) 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 leads to the proper terminals as said above to avoid error display. l The LCD will display OL indicating either open circuit or wrong polarity connection.
Model UT60H: OPERATING MANUAL Measurement Operation(11) Ω Note l The LCD displays OL indicating the tested capacitor is shorted or it exceeds the maximum range. l Analogue bar graph will be disabled when measuring capacitance. l It is normal to take a while when measuring high capacitor 400 F. The analogue bar graph at this time will show the time left before finishing the measurement.
Model UT60H: OPERATING MANUAL Measurement Operation(12) I. Frequency Measurement (see figure 9) ( figure 9) Warning To avoid harms to you, please do not attempt to input voltage higher than 30V rms. The measurement ranges are:40Hz, 400Hz, 4kHz, 40kHz, 400kHz, 4MHz, 40MHz and 400MHz. To measure frequency, connect the Meter as follows: 1. 2. 3. Insert the red test lead into the Hz terminal and the black test lead into the COM terminal. Set the rotary switch to Hz.
Model UT60H: OPERATING MANUAL Measurement Operation(13) J. Temperature Measurement (see figure10) ( figure 10) Warning To avoid harms to you, please do not attempt to input voltages higher than 60V DC or 30V rms AC. o o The temperature measurement range is -40 C~400 C.

Set the rotary switch to C/EF and press SELECT to select EF measurement mode. 2. Place the housing front part near the object being measured. 3. The LCD displays “EF”. The Analogue bar graph indicates the AC signal between 50~400V.
Model UT60H: OPERATING MANUAL Sleep Mode To preserve battery life, the Meter automatically turns off if you do not turn the rotary switch or press any button for around 30 minutes. The Meter enters into sleep mode The Meter can be activated by turning the rotary switch or pressing any button except POWER and Low imp. 200KΩ button. To disable the Sleep Mode function, press MAX MIN or REL button while turning on the Meter.
Model UT60H: OPERATING MANUAL The Use of Relative Value Mode The REL mode subtracts a stored value from the present measurement value and displays the result. For instance, if the stored value is 20.0V and the present measurement value is 22.0V, the reading would be 2.0V. If a new measurement value is equal to the stored value then display 0.0V.
