1、 Applicable scope:
1. This instrument is suitable for measuring the voltage drop of similar connection ports such as non reconnected plug pins and connecting plug lead wires, in order to determine the quality of the connection port. It can also check the wire breakage of the plug wire after completing the bending test times specified in the standard.
2. It is also suitable for voltage drop testing of switch contacts, relays, switches, wire harnesses, crimping terminals, connectors, and other related products
2、 Meet standards:
Meeting standards: SAE/USCAR38 2009 QC/T 730-2005; ISO 6722:2002 GB/T 2951-1997; GB/T 3048-1994 QC/T29106-2004; QC/T413-2002; QC/T413-2002; At the same time, it meets the requirements and testing specifications of national standards such as Germany, France, South Korea, Japan, and other countries. When the voltage drop experiment uses the crimping method, the voltage drop in the conductor crimping area should not be greater than QC/T 29106-2014-4.4.7 as shown in Figure 3. QC/T29106-2004 Standard 5.7 Conduct the experiment QC/T29106-2004 Standard: 5.7 Voltage drop experiment at the crimping point between the terminal and the wire. As shown in Figure 2, measure between two points at the middle position of the crimping point between the terminal and the wire, resulting in a 75mm long wire (with the insulation layer removed and firmly brazed). After deducting the 75mm long wire voltage drop, the voltage drop at the crimping point between the terminal and the wire is calculated. When two or more wires are connected to a terminal at the same time, current is applied to each wire to measure the voltage drop
