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:

lIf the range is too low for the input, the Meter displays

to indicate an overload.

lIf the range is too high, the Meter will not display

the most accurate measurement.

B. Manual Ranging and Autoranging

The Meter has both manual range and autorange options:

lIn 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.

lIn the manual range mode, you select 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.

To enter and exit the manual range mode:

1. 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 UT60D: OPERATING MANUAL

15

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

lIf you manually change the measurement range

after entering Hold mode, the Meter exits this mode.

lUnder diode, continuity and A range measurement,

only manual range mode is available.

Measurement Ranges (2)

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)

(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. Insert the red test lead into the HzV terminal and

the black test lead into the COM terminal.

2. Set the rotary switch to V Hz and press BLUE

button to select AC measurement mode.

3. 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).

Note

lIn 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).

blackred

Model UT60D: OPERATING MANUAL

17

Measurement Operation (2)

lWhen AC voltage measurement has been

completed, disconnect the connection between the

testing leads and the circuit under test.

DC Voltage Measurement (see 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. Insert the red test lead into the HzV terminal and

the black test lead into the COM terminal.

2. Set the rotary switch to V Hz; DC measurement

is default or press BLUE button to select DC

measurement mode.

3. Connect the test leads across with the object being

measured.

The measured value shows on the display.

Note

lIn 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).

lWhen DC voltage measurement has been

completed, disconnect the connection between the

testing leads and the circuit under test.

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)

Measurement Operation (3)

To test for continuity, connect the Meter as below:

1. Insert the red test lead into the HzV terminal and

the black test lead into the COM terminal.

2. Set the rotary switch to and press BLUE

button to select measurement mode.

3. The buzzer sounds if the resistance of a circuit under

test is less than 50 .

Note

lThe LCD displays indicating the circuit being

tested is open.

lWhen continuity testing has been completed,

disconnect the connection between the testing leads

and the circuit under test.

Testing Diodes (see figure 6)

Measurement Operation (4)

(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. Insert the red test lead into the HzV terminal and

the black test lead into the COM terminal.

2. Set the rotary switch to and press BLUE

button to select measurement mode.

3. 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.

The measured value shows on the display.

Note

lIn 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.
