Measurement of each additional voltage ratio on the same divider with the same applied voltage as in 1 1所述的同一测试电压的同一分压器的每一额外电压比。
Ac voltmeters will normally be calibrated at 5 test voltages for one range to establish the scale linearity 交流电压表一般以一个量程的五个测试电压值进行校正以定立标度线性。
To test passive components , the tester places a test voltage across the component under test and measures the current 在测试无源器件时，测试设备对被测试的器件施加一个测试电压后，测量电流。
The theoretical power measuring range is 37 . 5 w to 6 kw and the maximum test voltage and current are respectively 300 v and 20 a 理论上的功率量程为37 . 5w至6kw而最高测试电压及电流则分别为300v及20a 。
Measurements of voltage ratios are generally made at rated voltage of the divider but the maximum test voltage will be limited to 30 kv 电压比测量工作一般按分压器的额定电压进行，但最高测试电压不得超过30kv 。
Multifunction of testing voltage value , current value , rf value and transient current strength . it also acts as soldering station with option soldering pen 多用途测试电压值,电流值,射频值及瞬变电流强度等外,并设置焊笔接口,可选购焊笔作为焊台使用。
Measurement uncertainties will depend on the values of the voltage ratios being determined , the magnitude of the applied voltage and stability of the dividers under test 测量不确定度将视乎测试分压器的电压比率，测试电压值及该分压器的稳定性而定。
Solid state components not relied upon to reduce the risk of electric shock and that may be damaged by the applied dielectric potential may be disconnected for the test 不可能用来减少电击风险或有可能被所加的绝缘测试电压损伤的固态组件可以为测试而断开连接。
A luminaire shall withstand for a period of 1 minute , without breakdown , a test potential applied between live parts and accessible non - current - carrying metal parts , including parts accessible only during relamping 将一测试电压加在一个带电部件和一个非载流金属部件之间，灯具应能承受1分钟而不会出故障，包括只有在再开灯时才能接触的部件。
Calibration will be made by applying appropriate sinusoidal voltage and current signals with known phase relationship to the meter under test . the ranges of test voltages and currents are 25 v to 250 v and 50 ma to 100 a respectively 按已知的相位关系，将适当的正弦电压及电流讯号加于接受测试的功率因数表，以进行校正。测试电压及电流量程分别为25v至250v及50ma至100a 。
