Parameter:

No. Parameter Value
1 Model CA-300L
2 Input Voltage 85-265V AC
3 Output Voltage 0-300V DC Auto
4 Power 12W

Features:
1) Output voltage, current auto detection, and it can randomly test LED lamp bar or lamp bead;
2) The brightness is moderate and it will not hurt your eyes.(if you test for a long time, we still recommend you wear sunglasses)
3) It is very suitable for LED manufacturers, LCD TV maintenance LED lamp string, fast detection for lamp beads.

Function:
1>.Test electrolytic capacitor voltage resistance value (finish in 5 seconds)
2>.Test the stable value of stabilivolt diode (finish in 3 seconds)
3>.Test lamp bead or lamp bar voltage

Notice: if you do not use it for a long time, please unplug the power or close the AC switch for lengthening its service life

Test Pen Introduction:
1>.Total Length: 110cm
2>.Voltage: 1000V
3>.Current: 20A

Functions:
1>. Adopt 8-bit high speed MCU for voltage sampling test, and drive LED digital tube to display voltage
2>. Intelligent identify the lamp bead or lamp bar. When tests the lamp bead, MCU will automatically identify and start low current;
    when tests lamp bar, MCU will automatically detect and sample, then start timing; after 10s, it will output high current.
    If operating for a long time, the power can be up to 18W, and the peak power is 24W.
3>. 0-300V (error 1%) self-adaptive voltage, and it is suitable for most serial parallel lamp bead test.
    When testing, the voltage will automatically adapt, and it won’t burn the lamp bead.
    When testing the lamp bead, it is low current; when it is identified as lamp bead, it is high current.
    After the MCU timing for 10s, it can reach normal brightness. If the lamp bars are reversely connected, it won’t be burnt.
4>. Digital display real-time voltage output (actual error 1%), and the digital tube adopts red emitting diode.
    If it displays 00, it means short circuit; if it displays 300V, it means open circuit.
    Every group LED lamp bar should display the same voltage in the same LCD TV; if it is different, then it means the lamp bar has something wrong.
5>. Adopt self-restore fuse, and the chip has overheat, overcurrent protection. Cold hot ground are isolated, it is non-electric shock.
6>. Light LCD TV screen without disassembling. If you don’t disassemble the screen for test, please disconnect the LED backlight connection wire;
    and other device are normally on; let the TV ON then test, it will gain better results.
7>. Please do not use this tester to charge for charge and discharge devices (capacitors, batteries) in case of burning the tester.
