1. Specifications are applicable to all models (U1731C, U1732C, and U1733C) unless specified

2. The “AZ, AL, AC” and Offset are the accuracy specified at Impedance, Inductance, and Capacitance, respectively

3. The Zx, Lx, and Cx are the display count of the reading. For example, the Cx is 8888 as if the capacitance is 88.88 μF for the range of

200 μF.

4. The Quality Factor is the reciprocal of Dissipation Factor
