Brief Introduction:
U2922 series LED/diode checker can simultaneously check two-way double channel of LED/diode. CH2 can test the polarity direction of LED or diode; CH1 can test the forward VF value and reverse leakage current IR value of LED or diode. The upper limit and lower limit of VF and IR can be set. The compare results (HI/GO/LO) between the polarity of CH2 (+POL/-POL/NG) and LED VF/IR value of CH1 will be displayed after the end of the test.
Character large screen LCD can simultaneously display two-way value and polarity of VF1, VF2 / IR1, IR2 , which is particularly suitable for LED taping machines.
Features:
■ Two-way double-channel check of LED or diode (only U2922)
■ Precise bicolor LED polarity resolution capability (only U2922)
■ Selectable common anode or common cathode test mode (only U2922)
■ Diode geminate transistors can be tested (only U2922)
■ Up to 100mA forward test current (only U2922)
■ Simultaneous polarity test in two channels, forward VF1, VF2
■ Simultaneous test of LED/diode, reverse IR1, IR2
■ Large LCD screen and complete information display
■ High speed measurement: only 22ms
■ Easy operation
■ Parameter setup without loosing after shutdown
■ Standard Handler interface
■ Apply to dual LED, high speed screening and taping of diode
