Example calculation
1. Impedance (Z=500
Ω
) basic accuracy
Measurement conditions: test frequency = 10 kHz, speed = SLOW2,
range = 1 k
Ω
From Basic Accuracy Coefficient
Table, basic Z accuracy
coefficients A=0.08, B=0.001.
Inserting these in the calculation expression yields:
Similarly for
θ
basic accuracy coefficients A = 0.05, B=0.001, and thus:
2. Capacitance(Cs=160 nF) basic accuracy
Measurement conditions: test frequency = 1 kHz, speed = SLOW2
Test Z and
θ.
Measurement range: AUTO
When Z = 1.0144 k
Ω
,
θ
= -78.69 ,
test range is 10 k
Ω
From Basic Accuracy Coefficient
Table, basic Z accuracy
coefficients A=0.1, B=0.002.
Inserting these in the calculation expression yields:
Similarly for
θ
basic accuracy coefficients A = 0.05, B=0.001, and thus:
