DC Current. AC Current. Previous Page. Next Page. Page 3: Overview To avoid electric shock or personal injury, read the "Safety Information" and "Rules for Safe Operation" carefully before using the Meter. Digital Multimeter Model UT60A hereafter referred to as "the Meter" has autorange and manual range options with maximum reading The enclosure structure design adopted advanced "co-injection" IV V and double insulation.

Do not use the Meter if it is damaged or the case or part of the case is removed. 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. DC Direct Current. AC or DC. Double Insulated. Deficiency of Built-In Battery. Continuity Test. Capacitance Test. Refer to the Operating Manual. Conforms to Standards of European Union. Most Meter functions have more than one range.

See "Accuracy Specifications. 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. The Meter enters the manual range mode and turns off. When the highest range is reached, the Meter wraps to the lowest range. 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.

When continuity testing has been completed, disconnect the connection between the testing leads and the circuit under test. The measured value shows on the display. Note The test leads can add 0.

To obtain precision readings in low-resistance measurement, that is the range of Use the DC Voltage function to confirm that the capacitor is discharged. 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. Duty Cycle Measurement The duty cycle measurement range is 0. 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 V.

AC current is displayed as an mean value calibrated against sine wave effective value. 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. The Hold mode will not capture unstable or noisy readings. The Hold mode is applicable to all measurement functions. Deficiency of Built-In Battery. Continuity Test. Capacitance Test. Refer to the Operating Manual. Conforms to Standards of European Union.

Most Meter functions have more than one range. See "Accuracy Specifications. Selecting a Measurement Range Being in the right measurement range is important: l If the range is too low for the input, the Meter displays to indicate an overload. Manual Ranging and Autoranging The Meter has both manual range and autorange options: l In the autorange mode, the Meter selects the best range for the input detected.

This allows you to switch test points without having to reset the range. This allows you to override autorange and lock the Meter in a specific range. The Meter defaults to the autorange mode in measurement functions that have more than one range.

When the Meter is in the autorange mode, is displayed. The Meter enters the manual range mode and turns off. When the highest range is reached, the Meter wraps to the lowest range. The Meter returns to the autorange mode and is displayed.

Note l If you manually change the measurement range after entering the REL or Hold modes, the Meter exits these modes. To measure AC Voltage, connect the Meter as follows: 1. Connect the test leads across with the object being measured. The measured value shows on the display, which is effective value of sine wave mean value response.

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. To measure DC voltage, connect the Meter as follows: 1. The measured value shows on the display. If the circuit impedance is less than or equal to 10k , the error.

Testing for Continuity see figure 5 -g Select red black all figure 5 To test for continuity, connect the Meter as below: 1. Set the rotary switch to and press BLUE button to select measurement mode.

The buzzer sounds if the resistance of a circuit under test is less than Testing Diodes see figure 6 Select 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, and then measures the voltage drop across the junction. A good silicon junction drops between 0. To test a diode out of a circuit, connect the Meter as follows: 1. For forward voltage drop readings on any semiconductor component, place the red test lead on the component's anode and place the black test lead on the component's cathode.

Resistance Measurement see figure 7 Select red black figure 7 The resistance ranges are: To measure resistance, connect the Meter as follows: 1. Set the rotary switch to , resistance measurement is defaults or press BLUE button to select measurement mode.

Note l The test leads can add 0. To obtain precision readings in low-resistance measurement, that is the range of Use the DC Voltage function to confirm that the capacitor is discharged. The Meter's capacitance ranges are: To measure capacitance, connect the Meter as follows: 1. Set the rotary switch to. To measure frequency, connect the Meter as follows: uid 1. Connect the test leads across with the object being -g measured.

Input scope 30V rms frequency signal: Follow the above step 2 carrying out the measurement. Duty Cycle Measurement The duty cycle measurement range is 0. To measure duty cycle: 1. Set up the Meter to measure frequency. Note l The LCD displays 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. When the testing leads are connected to the current terminals, do not parallel them across any circuit.

The A Hz has a To measure current, do the following: 1. Turn off power to the circuit. Discharge all high- voltage capacitors. 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. AC current is displayed as an mean value calibrated against sine wave effective value.

Break the current path to be tested. Connect the red test lead to the more positive side of the break and the black test lead to the more negative side of the break. Turn on power to the circuit.

Note l For safety sake, the measuring time for high current should be 10 seconds for each measurement and the interval time between 2 measurements should be greater than 15 minutes. 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.

If a new measurement value is equal to the stored value then display 0. The Hold mode will not capture unstable or noisy readings. IV V overvoltage and double insulation standard. Open circuit voltage approximate 0. Displays approximate forward voltage drop reading 0. Maximum input amplitude: 30V rms.
