146-4080 (1)     数字万用表总成    
( 1 ) 该万用表可使用 RS232C 电缆连接至笔记本电脑或 Dataview 工具总成以进行故障诊断与排除。

有关维修 Sure Seal 接头的说明,请参考专门说明书, SMHS7531。 关于 Deutsch "DT" 型接头的维修说明,请参阅专门说明书, SEHS9615。

不需要 Cat® 电子技师 (Cat ET) 维修工具来确定和清除诊断代码。 但是,使用 Cat ET 确定诊断代码的过程更快更简单。 Cat ET 还可以显示诊断代码的历史记录信息以及诊断代码的参数状态。 这些特性使得 Cat ET 成为故障诊断和排除中的有益工具。

使用数字万用表进行导通性检查或电压测量。 有关数字万用表的使用方法,请参阅万用表附带提供的用户手册。 7X-1710 万用表表笔 用于在不断开接头的情况下测量接头上的电压。 把表笔电缆沿导线推入接头的背面。 8T-8726 适配器电缆 有一条 3 针叉接线束。 适配器电缆用于进行传感器电路的测量。

注: 除了线束测试之外,对于当今的 Cat 电气电路不推荐使用例如 8T-0500 导通性测试仪 的导通性测试仪或例如 5P-7277 电压测试仪 的电压测试仪。
