Touch the red test probe tip to the positive side of the circuit. Read the voltage value in the display. Frequency When ACA is selected, the measured frequency can be viewed in the lower display. EX622-en-GB_v2.8 4/15 contact: www.ponpe.com sale@ponpe.com... -
Page 7: Resistance Measurements
If one reading displays a value (typically 0.400V to 01.800V) and the other reading displays OL, the diode is good. If both readings display OL the device is open. If both readings are very small or ‘0’, the device is shorted. EX622-en-GB_v2.8 4/15 contact: www.ponpe.com sale@ponpe.com... -
Page 8: Capacitance Measurements
Touch the red test probe tip to the other side of the device. Read the Frequency value on the upper large display. Read the Duty Ratio on the lower small display. Press the MODE button to display the Duty Ratio on the large display. EX622-en-GB_v2.8 4/15 contact: www.ponpe.com sale@ponpe.com... -
