minutes. I would provide the test fixture.Finished board is connected to AC power,high voltage output is connected to light bulb loads, service port connected to PC serial port(I'll provide the SIM program),flow sensorinput from pulse circuit,conductivity readings from potentiometer,all other input are on off.All this is built into the tester,you just plug into the connetors,you read the flow, the temp,the conductivity,the other inputs in the sim program,you manually test the leds and the relays and the test id done. Unplug and insert new board.We would start out 100% then quickly move to a couple per lot once we were convinced we got all the problems.We will pull a few from each shipment for test if no problems then we can adjust the testing to minimum.If there are problems we ratchet back up to more testing.测试过程将持续五分钟。

Notes
[2] Electrons which are forced out of their orbits can result in a lack of electrons where they leave and an excess of electrons where they come to rest 本句中的主语是electrons，谓语是can result in， a lack of electrons where they leave and an excess of electrons where they come to rest是 宾语。这个宾语由and连接的名词短语a lack of electrons以及an excess of electrons组成，两个where引导地点状语，在理解时要分 清这里面的层次。 由于电子从轨道移走而造成该原子缺少电子，而移入电子的原子电子 过剩。使由于质子数多余电子数，缺少电子的成为正电荷。
参考译文
1.3 电荷之间的吸引和排斥 俗话说， 异性吸引” 处理电荷时是正确的。 俗话说 ， “ 异性吸引 ” ， 处理电荷时是正确的 。 每个 电荷四周有一个看不见的电场。 电荷四周有一个看不见的电场 。 当两个电性相同的电 荷靠近时电场将相斥， 荷靠近时电场将相斥 ， 当两个电性不同的电荷靠近时 电场将相吸。 电场将相吸 。 电荷周围的电场通过不可见的电力线表 示 ， 不可见的电力线表示引起吸引和排斥的不可见的 电场。 正电荷用离开的电力线表示、 电场 。 正电荷用离开的电力线表示 、 负电荷用进入的 电力线表示。 电力线表示。
Notes
[3] Trying to measure even small values of current would result in unimaginably large numbers. 本句的主语是一个动名词短语trying to measure even small values of current，谓语是动词词组result in，result in不能 机械地理解为“导致”，因为“导致”带有明显的感情 色彩，理解为“造成”更顺畅。 试图测量电流微小的值将产生难以想象的巨大的数字。

电力专业英语翻译(第二版)
A decrease in the field current gives rise to lagging (inductive) current in the stator; and increase in the field current that overexcites the motor causes a leading (capacitive) current to appear in the stator.励磁电流减小时，定子电流感性增强；励磁电流增加使电机过励时将在定子中产生容性电流。
An induction machine is an AC two-winding unit in which only one (primary, usually the stator) winding is supplied with an alternating current at a constant frequency ω1 from an external source.感应电机是一种具有双绕组的交流电气设备，它只有一个绕组（一次侧，通常是定子）通过外电源输入固定频率为ω1的交变电流。
Current transformers for protection are essentially similar to those used for the operation of ammeters, watthourmeters and other instruments.保护用电流互感器基本上同操作用的电流表、电能表和其他仪器类似。
DG planning also involves arranging for connection of the renewable power generator with the local grid, and for support of any local electric load when the renewable source is not available.分布式发电规划还包括安排可再生能源发电机与地方电网相连接，这样当可再生能源不可用时，本地电力负荷仍能得到支持。
