The Sencore LC75 (also known as the "Z Meter II") is a vintage digital capacitor and inductor analyzer designed to test component values, equivalent series resistance (ESR), and high-voltage leakage up to 600V.
Key Features and Uses
• Capacitance & Inductance: Accurately measures capacitor values and inductor parameters across multiple ranges.
• High-Voltage Leakage Testing: Applies up to 600V DC to test electrolytic capacitors under real operating voltage conditions and measure actual leakage current in microamps (μA).
• ESR Testing: Measures Equivalent Series Resistance to identify failing or dried-out capacitors, often while still in-circuit.
The item is in used and functional, seem to measured accurately.
You can get what you can see in pictures.
Power up and seems to work, measuring the 20uF, 100uF and 2.2uF in the photo.
Tested unknown inductors and it shows its value.
Pull out chart for instructions how to use look excellent.
Sold as-is due to age, and no way to confirm all functions and accuracy of the unit.
A photocopy of Operation Manual, Schematics & parts list, calibration procedure and circuit description included.
Please, carefully review all attached photos which is part of the descriptions.
