One example of a multiple closure would be to route a single device output to two instruments, such as a voltmeter and a frequency counter.
复用开关的一个简单例子就是将单台设备的输出连接到2台仪器，例如一台伏特表和一台频率计数器。
The output trigger may be connected to a measuring device, such as a voltmeter. This will ensure the measurement is not made until the switch contacts have fully settled.
输出触发可被连接到一个测量装置，例如伏特计。这样能够确保在开关触点完全稳定之后再进行测量。
When an unknown signal is connected to a measuring device, such as a voltmeter or ammeter, the measurement accuracy is almost entirely determined by the measuring device.
当一个未知的信号被连接到测量装置时，例如伏特计或安培表，测量准确度则几乎完全由测量装置决定。
