OPERATION:
Auto Ranging Mode
The meter defaults to autoranging mode when powered on. In this mode, the
meter automatically selects the best range to display the measurement.
Manual Ranging Mode
By pressing the Range button on the meter, the manual range mode will override
the autoranging feature of the meter. “RANGE” appears in the the display.
Continue pressing the Range button until the desired range is obtained. The
ranges will cycle from lowest to highest. Use this mode to lock in a specific
range for repeated measurements.
To return to the autoranging mode, either depress the Range button for greater
than 2 seconds or turn the meter off and then back on again.
Data Hold Feature
Press the Hold button on the meter to toggle in and out of the data hold mode.
“HOLD” appears in the display when data hold is active. Use the data hold fea-
ture to lock a measurement reading on the display. Press the Hold button again
to unlock the display and obtain a real-time reading.
Mode Switch (AC/DC) & (
Ω
/ / ) Feature
Press this button to switch between AC and DC in the voltage measurement
mode of the function switch. Press this button to toggle between ohms, continu-
ity, and diode functions when in the
Ω
/
/
position of the function switch.
The meter display will indicate which function is selected.
Auto Power Off (APO) Feature
The meter automatically powers itself down after about 10 minutes of no use.
Press any button, and the meter will wake up and display the last reading taken
before power down. This feature can be overridden by holding the Range button
while sliding the function switch from Off to any other position. Turning the
meter off will restore the APO default.
Measuring Voltage:
• Slide the function switch to the
Volt
position.
Note: The measurement mode defaults to AC voltage.
• If measuring DC voltage, use the AC/DC button to toggle to DC voltage. The meter
display will confirm the active mode (AC or DC) on the left side of the display.
• Hold the test leads behind the finger guards and apply the lead tips in parallel
to the circuit under test.
• The meter will sense the level of voltage, automatically range to obtain the best
resolution, and accurately display the measurement.
Note: To measure millivolts, use “RANGE” button to manually select mV range.
CAUTION: For maximum safety, do not hold the meter in your hands
while measuring higher voltages.
If the meter displays zero or low volts, ensure that the meter is prop-
erly set to measure AC or DC volts and verify on a known live source.
Measuring Resistance (Ohms):
• Verify the circuit is de-energized to obtain accurate measurements.
• Slide the function switch to the
Ω
/ /
position.
Note: The measurement mode defaults to Ohms (
Ω
).
• Hold the test leads behind the finger guards and apply the lead tips to the
component or circuit under test.
• The meter will sense the level of resistance, automatically range to obtain the best
resolution, and accurately display the measurement.
Verifying Continuity ( / ):
• Verify the circuit is de-energized.
• Slide the function switch to the
Ω
/ /
position.
Note: The measurement mode defaults to Ohms (
Ω
).
• Press the
Ω
/
/
button once to toggle to Continuity. The meter display
should show the
/
in the upper right corner.
• Hold the test leads behind the finger guards and apply the lead tips to the
component or circuit under test.
• The meter will sense the level of resistance and beep if the resistance is less
than 25
Ω
to confirm that continuity is present.
