NOTE: On some low AC and DC voltage ranges, with the test leads not

connected to a device, the display may show a random, changing reading.

This is normal and is caused by the high-input sensitivity. The reading will

stabilize and give a proper measurement when connected to a circuit.

6.1. MODE BUTTON

To select Diode/Continuity or DC/AC voltage, current, temperature (°C/°F)

When the meter is first turned on, it automatically goes into Auto ranging.

This automatically selects the best range for the measurements being

made and is generally the best mode for most measurements. For

measurement situations requiring that a range be manually selected,

perform the following:

1. Press the RANGE button. The "AUTO" display indicator will turn off.

2. Press the RANGE button to step through the available ranges until

you select the range you want.

3. Press and hold the RANGE button for 2 seconds to exit the Manual

Ranging mode and return to Auto Ranging.

The Data Hold function allows the meter to "freeze" a measurement for

later reference.

1. Press the DATA HOLD button to "freeze" the reading on the indicator.

The indicator "HOLD" will be appear in the display.

2. Press the DATA HOLD button to return to normal operation.

The max. Hold position is used to measure the maximum value. The

maximum measured value is up dated continuously. Press the button once

again to release the hold and allow a further measurement.

CAUTION: Do not measure DC voltages if a motor on the circuit is

being switched ON or OFF. Large voltage surges may occur

that can damage the meter.

Set the function switch to the V DC position ("mV" will appear in the

display).

Insert the black test lead banana plug into the negative (COM) jack

and the red test lead banana plug into the positive (V) jack.

Touch the test probe tips to the circuit under test. Be sure to observe

the correct polarity (red lead to positive, black lead to negative).

Read the voltage in the display. The display will indicate the proper

decimal point and value. If the polarity is reversed, the display will

show (-) minus before the value.
