0.001 ohms
0.1001 ohms
10^5
100 ohms
The power consumption of a PMMC instrument is typically about 0·25 mW to 2 mW. [True/False]
In measurement systems, undesirable static characteristics are
Sensitivity and Accuracy
Drift, Static Error and Dead Zone
Reproducibility and Non-linearity
Drift, Static Error; Dead Zone and Non-linearity
Fast Response and Fidelity are the desirable dynamic characteristics of a measurement system. [True/False]
