	5.5 位模型中最高的满量程计数值。（2004年11月岩津测试仪器株式会社研究）

	隔离式 2 路输入，双显示器（仅限 VOAC7523H/7520H）
	提供两个直流测量输入。两个通道彼此隔离。电压比较两个不同电路之间或电位差测量之间同一电路中的部件可以轻松执行。单个VOAC7523H/7520H 单元可以执行通常需要两个单元的直流电压测量，从而节省安装空间并提高测量速度。 VOAC7523H/7520H还具有双显示功能，可显示测量值用于其他功能。例如，更改输入电缆连接或功能切换需要对现有功能进行不同功能的测量单显示万用表。单个VOAC7523H/7520H装置可以执行这些操作同时进行两种类型的测量。

	双显示
	传统上，电缆断开和功能切换需要执行不同类型的测量。A VOAC752xH 系列单个单元可以执行需要多个单元的测量提高测量效率。例如，在测量功耗（视在功率，VA）时，同时测量和操作电压和电流使能实时功率测量。
