Measuring Duty - KPS -PA60 Manual De Funcionamiento

NOTE:
1) 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 not be en-
sure.
2) " "means the maximum input voltage is 600V rms AC.
4.13.3 By HZ/DUTY range:
Beware of Electrocution. Pay special attention to avoid electric shock
when measuring high voltage. Do not input the voltage which 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 test leads to the two ends of the source or load for measurement.
• Take the reading on the LCD.

4.14 Measuring duty

4.14.1 By A range ( from current clamp):
• Set the rotary selector to the A range position.
• Press the trigger to open jaw. Fully enclose only one conductor.
• Press the "Hz/%" to switch to the DUTY measurement.
• Take the reading on the LCD.
NOTE:
1) Do not put more than one cable into the jaw during test, otherwise incorrect
test value might be obtained.
2) If the duty cycle is less than 10%, symbol „UL‟ will be displayed on LCD;
if the duty cycle is more than 94.9%, symbol „OL‟ will be displayed on LCD.
3) The input signal frequency range is 10 – 1kHz. It is possible to test duty
cycle of the higher than 1 kHz frequency signal, but the tolerance of the test
result can not be ensure.
4) " "means the maximum input current is 1000A rms AC.
4.14.2 By V range:
• Plug the black test lead into the COM jack and the red test lead into the
KPS-PA60 • Digital clamp meter
