Manual Overview

The Sencore LC102 AUTO-Z manual provides guidance on interpreting readings from the capacitor-inductor analyzer, focusing on troubleshooting, error codes, diagnostics, calibration, and adjustments. The manual emphasizes understanding capacitor tolerances, particularly for electrolytic capacitors, which often read higher than their marked values due to frequency effects. Technicians are advised to enter both positive and negative tolerances into the LC102 for accurate readings. The manual also details the dielectric absorption (D/A) test, which is crucial for identifying capacitors with excessive D/A that may not fully discharge. The LC102 automates this test, charging capacitors to a reference level and monitoring recovery voltage to ensure reliable results. Technicians should be aware of the GOOD/BAD limits for D/A, which vary by capacitor type, and use these limits to assess capacitor health. The manual underscores the importance of allowing previous charge effects to dissipate before testing to avoid misleading results.
