* Do open/short calibration before measuring for above ranges with * to have better precision measurements.
If D > 0.1, the accuracy should be multiplied by
If D << 0.1 in capacitance mode ZC = 1/2πfC
If D << 0.1 in inductance mode ZL = 2πfL
Sub-display parameters accuracy
Ae = impedance (Z) accuracy
Definition: Q = 1/D & Rp = ESR * (1+1/D2)
D value accuracy De = ± Ae *(1+D)
ESR accuracy Re= ± ZM * Ae (Ω)
ie., ZM = impedance calculated by 1/2πf C or 2πf L
Phase angle θ accuracy θe= ± (180/π) * Ae (deg)
