When measuring the charge on a device such as a capacitor, it「s important to disable the zero check of the electrometer first, and then connect the capacitor to the high impedance input terminal.
在测量一个器件,如电容器上的电荷时,重要之点是要首先关闭静电计的零点检查功能,然后再将电容器连到高阻抗输入端。
High resistance insulation in the test circuits is one of the first requirements of making successful electrometer measurements.
在测试电路中,高绝缘电阻是成功地进行静电计测量的首要要求之一。
Isolation resistance measurements are usually made by sourcing a voltage, then measuring the resulting current using an electrometer or picoammeter.
在测量隔离电阻时,通常是提供一个电压,然后利用一个静电计或皮可安培计测量形成的电流。
The damping circuit may already be built into the electrometer or may be an external circuit.
衰减电路可以装在静电计的内部,也可以是一个外部电路。
Notice that this is a two-wire resistance measurement compared to using the electrometer voltmeter and external current source, which can make a four-wire measurement.
注意,这种测量方法是两线电阻测量,而使用静电计电压表和外部电流源则可以进行四线测量。
Connect an electrometer to the switch card output and measure the cur rent.
将一个静电计连接到开关卡输出并测量电流。
Quartz has properties similar to sapphire, but considerably higher piezoelectric output, so it」s rarely used in electrometer circuits.
石英具有类似于蓝宝石的性质,但是其压电输出相当高,所以很少用于静电计电路中。
Therefore, it's prudent to measure the insulation resistance of the test fixtures and cables periodically with an electrometer ohmmeter to ensure their integrity.
因此谨慎的做法是定期地用静电计欧姆计来测量测试夹具和电缆的绝缘电阻,以保证其完整性。
Figure 2-24 shows a protection circuit for an electrometer ammeter or picoammeter, consisting of a resistor and two diodes (1n3595).
图2 - 24示出静电计或皮安计的过载保护电路,其中包括一个电阻器和两个二极管(1n3595)。
Figure 2-33 shows the electrometer ohmmeter measuring a resistance (R).
图2-33示出静电计欧姆计测量电阻(R)的情况。
The resistors (RL) are current limiting resistors used to protect the switches and electrometer from high current.
电阻器(RL)是电流限制电阻器,用来保护开关和静电计不受大电流的损害。
Figure 1-18 shows the basic configuration of an alternative form of electrometer ohmmeter.
图1 -18示出另一种形式的静电计欧姆计的基本电路结构。
Here, an electrometer ohmmeter is forcing a current (IR) through the unknown resistance (RS) and then measuring the voltage (VM) across the DUT.
静电计欧姆计的电流激励(IR)流过未知电阻(RS),然后测量dut上的电压(VM)。
The measured current is usually quite small, so a picoammeter or electrometer is often required to make the measurement.
测得的电流通常非常小,因此往往需要使用皮安计或静电计进行测量。
The ohmmeter USES an internal current source and electrometer voltmeter to make the measurement.
欧姆计使用内部的电流源和静电计电压表来进行测量。
The circuit of the electrometer when used as a voltmeter is actually as shown in Figure 2-6.
当静电计作为电压表使用时,其电路实际上如图2 - 6所示。
