incorrect test value might be obtained.
•
Frequency test range is 10Hz - 1kHz. "00.0" will be displayed
on the LCD if the test frequency is lower than 10.0Hz. It is
possible to test a frequency, which is higher than 1kHz, but the
tolerance of the test result can't be ensured.
•
"
" means the maximum input current is 400A rms AC.
MEASURING FREQUENCY BY V RANGE
•
Beware of electrocution.
•
Pay special attention to avoid electric shock when measuring high voltage. Do
not input voltage, which is more than 750V rms AC.
Plug the black test lead into the COM jack and the red test lead into the INPUT

jack.
•
Set the rotary selector to the V~ range position.
•
Press the "Hz/%" key to switch to frequency measurement.
•
Connect the test leads to the two ends of the source or load for measurement.
•
Take the reading on the LCD.
Note: Frequency test range is 10Hz - 10kHz. It is possible to test the frequency, which
is higher than 10kHz, but the tolerance of the test result can't be ensured.
•
"
" means the maximum input voltage is 750V rms AC.
MEASURING FREQUENCY BY HZ/DUTY RANGE
•
Beware of electrocution.
•
Pay special attention to avoid electric shock when
measuring high voltage. Do not input voltage, which is
more than 250V rms AC.
•
Plug the black test lead into the COM jack and the red test
lead into the INPUT jack.
•
Set the rotary selector to the HZ/DUTY range position.
•
Connect the test leads to the two ends of the source or load
for measurement.
•
Take the reading on the LCD.
MEASURING DUTY CYCLE BY A RANGE (FROM CURRENT CLAMP)
•
Beware of electrocution.
•
Ensure that the test leads are disconnected from the meter before making
current clamp measurements.
Set the rotary selector to the A range position.
•
•
Press the trigger to open the jaw and fully enclose only one conductor.
•
Press the "Hz/%" button to switch to Duty Cycle measurement.
•
Take the reading on the LCD.
