Measurement Considerations

NOTICE: Read and understand all warning and caution statements

listed in the safety section of this operation manual prior to using this

meter.

1. Always move the rotary function switch to the OFF position when the

meter is not in use. This meter has Auto Power OFF that

automatically shuts the meter OFF if 17 minutes elapse without

activity.

2. If "OL" appears on the display during a measurement, the

measurement exceeds the range selected. Change to a higher range.

AC/DC Voltage Measurements

1. Insert the black test lead into the negative COM jack and the red test

lead into the positive V jack.

2. Set the function switch to the "VAC" "VDC" "mV" position. Press the

SELECT key momentarily to toggle between AC and DC.

3. Read the voltage measurement on the display

AC/DC Current Measurements

CAUTION: Do not make current measurements at 20A for longer than

30 seconds. Exceeding 30 seconds may cause damage to the meter

and/or the test leads.

1. Insert the black test lead into the negative COM jack.

2. For current measurements up to 4000

µA, set the function switch to

the "

µA" position and insert the red test lead into the mA-µA jack.

3. For current measurements up to 400mA, set the function switch to the

"mA" position and insert the red test lead into the mA-

µA jack.

4. For current measurements up to 10A, set the function switch to the

"A" position and insert the red test lead into the A jack.

5. Press the SELECT key momentarily to toggle between AC and DC.

6. Remove power from the circuit under test and open the circuit at the

point where you wish to measure current.

7. Touch the black test probe tip to the negative side of the circuit and

touch the red test probe tip to the positive side of the circuit.

8. Apply power to the circuit.

9. Read the current on the display
