Note: Do not put more than one cable into the jaw during the
test, otherwise incorrect values may be obtained.
•
If the duty cycle is less than 10%, the symbol "UL" will be
displayed on the LCD and if the duty cycle is more than
94.9%, the symbol "OL" will be displayed on the LCD.
•
The input signal frequency range is 10 - 1kHz. It is
possible to test duty cyle of a frequency signal higher
than 1kHz, but the tolerance of the test result can't be
ensured.
•
"
" means the maximum input current is 400A rms AC.
MEASURING DUTY CYCLE BY V RANGE (FROM CURRENT CLAMP)
•
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 V~ range position.
•
Press the "Hz/%" button to switch to DUTY
measurement.
•
Connect the test leads to the two ends of the
source or load for measurement.
•
Take the reading on the LCD.
Note: If the duty cyle is less than 10%, the symbol
"UL" will be displayed on the LCD and if the duty cycle
is more than 94.9%, the symbol "OL" will be displayed
on the LCD.
•
The input signal frequency range is 10 - 10kHz.
It is possible to test the duty cycle of a frequency
signal higher than 10kHZ, but the tolerance of the
test result can't be ensured.
•
"
" means the maximum input voltage is 750V
rms AC.
MEASURING DUTY CYCLE 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.
•
Press the "Hz/%" button to switch to Duty Cycle measurement.
•
Connect the test leads to the two ends of the source or load for measurement.
