HKD-2030E-A
LED dot matrix board tester Introduction
First, the machine summary:
This applies to 32 (A type, B type) or 64 (C-type) pins within the various LED displays. No jumper board and programming, automatic identification devices, materials and labor for cutting, an electric performance test, visual appearance, light leakage checking and other functions.
Second, the machine features:
A, detection of 32 (A type, B type) or 64 (C-type) pins within the various LED display and performance of various electrical parameters. Automatic Identification (scan), or manually edit all kinds of LED display pin and testing parameters.
B, test items: VFH (mA current), VFL (uA current), IR, light leakage inspection, the line (or section) and the line (or section) short circuit, the column (or words) and columns (or words) short circuit, the line ( or section) and column (or words) short circuit check and display the display circuit pin, open inspection, brake fluid effect, the whole point of light by visual appearance.
C, testing is completed, for more than the standard (set value) of the bad points from the measured LED display and LED display panel has a corresponding negative reasons, while the digital control panel displays the IR maximum, VF (mA current) minimum , VF (mA current) maximum.
D, the measured full-light or LED can display a variety of graphics, visual appearance and leaked examination.
E, four groups were set to VF (mA current) and. VF (uA small current), the lower limit. Two mA current were set, one can complete with a LED display eight different requirements (two forward mA current, four groups of VF, the lower limit) the detection of the die LED, LED display can not help on the same material in four to detect and display.
F, a single LED can display the test value. Bad points automatically display a variety of detection value and number of values.
G, may choose to pre-test with the IF VF IR pre-test the impact and the impact of using VR
H, microcomputer control, power and memory, test, high stability, long-term use of free adjustments.
Third, the technical parameters:
A, measurement. VF (uA current) when the forward current source IFL: 1 ~ 999uA
B, measured VF (mA current) when the forward current source IFH: 1.0 ~ 99.9mA
C, forward voltage measurements VF: 0.01 ~ 9.99V
D, measured when the reverse voltage IR VR: 0.01 ~ 9.99V
E, reverse current measurement value of the IR: 00 ~ 999uA
F, point forward when the full-light current source: 1.0 ~ 199mA
H, brake fluid effect detection voltage source: 0.01 ~ 9.99V
I, detection time: 0.1 ~ 100 seconds adjustable
J, Power supply: AC220V50HZ50W
Lattice detector
