Example calculation
1. Impedance (Z=500 Ω) basic accuracy
Measurement conditions: test frequency = 10 kHz, signal level = 1 V,
speed = SLOW2, range = 1 kΩ
From Basic Accuracy Coefficient
Table (0.501V to 1.000V) on the
following pages), basic Z accuracy
coefficients A=0.08, B=0.01.
Inserting these in the calculation expression yields:
Similarly for θ basic accuracy coefficients A = 0.05, B=0.005, and thus:
2. Capacitance(Cs=160 nF) basic accuracy
Measurement conditions: test frequency = 1 kHz, signal level = 1 V,
speed = SLOW2
Test Z and θ.
Measurement range: AUTO
When Z = 1.0144 kΩ, θ = -78.69 ,
test range is 10 kΩ
