Data Hold
• If the result is an open circuit (or the measured circuit
resistance is higher than 200
Ω
) “
0L
” is displayed.
Frequency/Duty Cycle
Use caution when measureing high voltage circuits
to avoid electrical shock and injury. do not test
voltages higher than dc/ac 600v.
Warning
•
Make sure the probe cap is screwed on if making CAT III
or higher measurements.
•
Insert the black test lead or test clip in the “
jack.
•
Set the rotary switch to the “
Hz%
” position; “Hz” is
displayed.
•
Connect the probe tip of the meter and tip of the test
lead (or test clip) across the source or load for
measurement and read the measured frequency on the
display.
•
Press “
Hz%”
to switch to duty cycle measurement; “%”
is displayed.
•
Connect the probe tip of the meter and tip of the test
lead (or test clip) across the source or load for
measurement and read the measured duty cycle on
the display.
•
Alternatively, while in AC voltage or AC current modes,
pressing the
“Hz%”
button will switch to frequency
mode.Press the button again to switch to duty cycle.
Press the button a third time to return to voltage/current
mode.
COM”
To hold a reading, press the“ / ”button and the current
reading will be held on the display. Press the button again
to return to normal reading.
Backlight
• Hold the“ / ”button for two seconds to turn on
backlight. The backlight will go off automatically after
10 seconds.
• Hold the“ / ”button again to manual turn off the
backlight.
Work light
While the meter is on in any position, hold the “ ”
button to turn on the work light.Use this in areas that are
poorly illuminated to make measurements easier.
NCV (Non-Contact Voltage)
While the meter is on in any position, hold the “
NCV
”
button to turn check for the presence of voltage. Move
the top of the meter toward the voltage source and if the
voltage detected is >110VAC, the meter will beep and
the NCV indicator will flash.
NOTE:
Do not rely solely on NCV detection to determine the
presence of voltage in a conductor.Socket design,
insulation, interference, etc. can affect detection.
Auto Off
When not in use, the Meter will automatically turn off after
approx. 15 minutes. After auto off, press “
FUNC
” to turn
the power back on. The Meter will beep 5 times 1 minute
before and a long beep right as it turns off.
Hold the “
FUNC
” button while turning on the meter to
disable auto off.
