Manual Overview

The Sencore Tech Tips manual #139 provides guidance on testing non-polarized electrolytic capacitors using the Z-METER. Non-polarized electrolytic capacitors, commonly used in circuits without established polarity such as audio crossovers and AC motor start circuits, can be identified by their lack of polarity markings. The manual emphasizes the importance of testing these capacitors for value and leakage in both directions due to their unique construction, which resembles two polarized capacitors connected back-to-back. To perform the test, connect the Z-METER test leads to the capacitor, press the CAPACITOR VALUE button to check if the value is within tolerance, and then use the LEAKAGE VOLTAGE control set to the capacitor’s rated voltage. Press the LEAKAGE button, note the reading, reverse the leads, and repeat the leakage test. This ensures accurate assessment of the capacitor’s performance. The manual does not provide specific troubleshooting flow, error codes, or calibration instructions but focuses on the testing procedure.

Quick Issues Covered

• Type: manual
• File size: 434.0 KB

Manual Overview

The Sencore Tech Tips manual #134 provides guidance on testing ceramic capacitors using a Z-METER, focusing on troubleshooting, error diagnostics, and calibration. Ceramic capacitors, including monolithic types, exhibit value changes due to dielectric stress when DC biased. This stress causes temporary decreases in capacitance, which can be observed with a Z-METER after a leakage test. The manual explains that monolithic capacitors, which are compact and have high voltage ratings, may show significant value variations with applied voltage, making them unsuitable for circuits sensitive to voltage changes. The Z-METER uses a DC charging curve to determine capacitor values, often reading higher than AC impedance bridges. Technicians should replace failed capacitors with identical types to avoid circuit issues. The manual emphasizes understanding dielectric stress and absorption effects for accurate testing and advises against using different capacitor types without thorough circuit testing.

Quick Issues Covered

• Diagnose dielectric stress causing value change in ceramic capacitors.
• Identify monolithic capacitors' value fluctuation with DC bias on Z-METER.
• Trace circuit schematics for capacitor replacement to avoid operation issues.

Overview

The product is a Z-METER, which is used for testing ceramic capacitors. The manual covers topics such as the characteristics of ceramic capacitors, including temperature coefficients, tolerance, and color codes. It provides information on testing for dielectric stress and monolithic ceramic capacitors, and explains how the Z-METER’s value test circuits are sensitive to dielectric stress and absorption. The manual also advises on the proper testing and replacement of ceramic capacitors to ensure correct circuit operation.
