Detection of a triac with a multimeter resistance R * 1Ω block, with red, black and two pen were measured between any two pins positive and negative resistance, the result of which two readings of infinity. If a group of tens of ohms, the group of red and black two-pin connection table for the first anode A1 and the gate G SCR BTA312, another empty foot is the second anode A2. Determine A1, G pole, and then carefully measured A1, G pole between positive and negative resistance readings that measure relatively small black table pen connects to pin the first anode A1 SCR BTA208, the red pen access control electrode pin G. The black pen then identified a second anode A2, the red pen then the first anode A1, this time should not deflect the meter pointer SCR, resistance is infinite. Discrimination thyristor (SCR) SCR pin pin discrimination by the following methods: first with a multimeter to measure the resistance R * 1K block between tripod, the resistance of small feet were a control electrode and cathode, the remaining The kick for the anode. Then multimeter R * 10K block SCR BTA216, with fingers anode and the other foot, and do not let the feet touching, black pen then the anode, the red pen then the rest of the foot, such as the swing to the right hands , indicating that the red pen for the connected cathode-gate was not swinging. SCR BTA312, SCR, are fertile Electronics Dongguan City is provided by Wal-Electronic Technology Co., Ltd. Dongguan City is Wal-Electronic Technology Co., Ltd.
