嗨，我正在尝试设置一个实验来测量处理过程中设备的电流。
我想从设备发送一个触发器到DMM，以便在给定时间开始测量。
我无法找到用于触发输入的正确设置，即触发脉冲应使用的电压，脉冲的最小长度是多少。
一旦完成处理，是否可以停止测量？
处理所需的时间长度会有所不同，所以我只能为数字万用表设置一个预先计算的读数。

Hi, I am trying to setup an experiment to measure the current of a device during processing. I would like to send a trigger from the device to the DMM to start the measurement at a given
time. I am not able to find the correct settings to use for the trigger input i.e what voltage i should use for the trigger pulse, what is the minimum length of the pulse.
also, would it be possible to stop the measurements once i am done with the processing? The length of time required for processing will vary so i cant just set a precalculated number of readings for the DMM.
