The manual provides guidance on using the Z METER for leakage testing of capacitors, emphasizing the importance of selecting the correct voltage under the capacitor's rated voltage to prevent overloading during tests. It also addresses troubleshooting issues such as overrange indications and explains how to reform leaky electrolytic capacitors, while highlighting the need for caution when working with high voltages that pose a shock hazard.
Manual Overview
The Sencore Z Meter manual addresses common questions related to the leakage test function. It explains that high voltages are necessary for testing capacitors because leakage is not linear with voltage, and low-voltage ohmmeters cannot detect issues at operational voltages. When selecting test voltages, always choose one below the capacitor’s rated voltage to avoid overloading. If the display flashes “888,” it indicates an overrange condition, which could be due to incorrect range settings, a charging capacitor, or excessive leakage. For large capacitors, hold the LEAKAGE button to see if the condition resolves. The manual advises using a capacitor in parallel with the meter for accurate voltage readings, as the Z Meter’s output is rectified but not filtered, affecting voltmeter readings. The manual also highlights safety precautions, particularly with high voltages that pose shock hazards. Calibration and adjustments are not detailed, but the manual emphasizes correct range selection and voltage application for accurate testing.
