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.
Correct Incorrect
WARNING
•
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.
MEASURING FREQUENCY BY V RANGE
•
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.
WARNING
•
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.
MEASURING FREQUENCY BY HZ/DUTY RANGE
•
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)
WARNING
•
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.
