Also applies For measuring high-power direct current resistance test standard. 2. References This procedure refers to the following documents.

It consists of two copper connectors and between A plate or rod resistance components, the voltage drop across the shunt on the potential of the terminal mounted on the joint leads. Shunts The rated voltage drop at the standard value selection, such as 75mV. Shunt metrological parameters of the rated input current IN, Nominal output voltage UN and the nominal shunt resistor RN (RN = UN/IN), when applied to the input current shunt I1, this When the output voltage of the U2 (when the output current is zero), the actual definition of the shunt resistor is shown RM = U2/I1.4 metering performance requirements4.1 accuracy class 4.1.1 DC shunt accuracy level is divided into 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2 7 levels. Relative error is defined 4.1.2 DC shunt is. γ = U2-I1RNI1RN × 100% (1) 4.1.3 DC shunt relative error may also be equivalently expressed as. γ = RM-RNRN × 100% (2) Formula (1), the formula (2). γ --- shunt relative error; U2 --- shunt output voltage indication, mV; I1 --- shunt the input current indication, A; RN --- shunt resistor nominal value, mΩ; RM --- shunt resistor actual indication, mΩ. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 1069-2011_English be delivered?Answer: Upon your order, we will start to translate JJG 1069-2011_English as soon as possible, and keep you informed of the progress.
