Note: All accuracy is guaranteed by proper ratio resistor
calibration and open/short calibration.
If D > 0.1, the accuracy should be multiplied by
1
Z = if D << 0.1 in capacitance mode

Z = 2πf L if D << 0.1 in inductance mode

Sub-display parameters accuracy:
Ae = impedance (Z) accuracy
Definition: Q =
Rp = ESR (or Rs) * (1+1/D²)
1. D value accuracy: De = ±Ae × (1+D)
2. ESR accuracy: Re= ±Z
ie., Z = impedance calculated by
M
3. Phase angle θ accuracy: θe= ±(180/π) × Ae (deg)
