The probe can be used to check the continuity of all electronic circuits. Probe, also known as "test needle", is used to test a PCBA electronic consumable with good conductivity.

How to use the probe:

(1) After opening a hole in the resin plate (bakelite board, etc.), insert the probe seat. ). (See Figure 1) * For the hole size, please refer to the press-fitting hole size recorded on each page. (See Figure 2) * At this time, if there is a gap between the resin plate and the probe base, please fix it with adhesive before using it. ② After installation, connect it to the probe base. * When welding wires, please be careful not to let flux flow into the probe bracket. Otherwise, the probe may not work. * According to different environments, when there is no space for welding or wiring, please wire before pressing. ③ Insert the probe into the probe seat. (See Figure 1) * At this time, if the front end (plunger) is pressed hard, it may cause damage or function degradation.
