U1731C/U1732C/U1733C Electrical Specifications

Accuracy is given as ±(% of reading + counts of least significant digit) at 23 °C ± 5 °C, with relative humidity less than 80%. Please refer to

the User Guide about the measuring mode specified for each range of L/C/R, series or parallel mode. Measurements performed at the test

socket and necessary Open and Short corrections must prior be done. The accuracy is verified by design and specified type tests.

The accuracy for ranges 2 Ω to 200 Ω is specified after Null function is used to subtract the resistance of test leads and the contact resistance.

Notes:

a. For the ranges of 20 MΩ and 200 MΩ, the R.H. is specified for < 60%

c. Equivalence Series Resistance (ESR) measurement is determined by impedance measurement and range. The maximum

This accuracy for the ranges of 20 pF~2000 pF is specified after Math Null which is used to substrate the stray capacitances for test leads.

Notes:

a. The accuracy for the ceramic capacitor will be influenced depending on the dielectric constant (K) of the material used to make

the ceramic capacitor. For related influence factors, please refer to the Component dependency factors section in the Impedance
