The manual provides detailed instructions on how to reform aluminum electrolytic capacitors using a Z Meter, including connecting the capacitor to the test leads, selecting the appropriate leakage voltage, and using a hold-down rod to maintain the test button in position. It also covers troubleshooting steps, such as monitoring the leakage current and determining if the capacitor is reformable or needs to be discarded if the leakage does not drop to an acceptable level after several hours.
Manual Overview
The Sencore Tech Tip 170 manual provides guidance on reforming aluminum electrolytic capacitors using a Z Meter. Aluminum electrolytic capacitors can become defective due to prolonged inactivity, leading to increased dielectric absorption and leakage. The manual explains that reforming involves applying voltage to restore the dielectric oxide layer. To reform a capacitor, connect it to the Z Meter test leads, select the appropriate leakage voltage, and use the CAPACITOR LEAKAGE button with the hold-down rod to maintain voltage application. Monitor the leakage current; if it drops below the maximum allowable level, the capacitor can be used. If not, it should be discarded. The reforming process may take from a few minutes to several hours. If successful, the capacitor should be rechecked after 30 minutes to confirm improvement. If the leakage remains high, the capacitor is considered defective. The manual emphasizes the importance of timely reforming to extend the capacitor’s life.

Basic Usage / Operation Tips
Begin by carefully discharging the capacitor and inspecting it for any visible damage. Use a variable DC power supply to slowly increase voltage to the capacitor, starting at a low level and gradually ramping up while monitoring leakage current. This controlled reforming process helps restore the capacitor’s dielectric layer. Always allow sufficient time at each voltage step to ensure the capacitor stabilizes before increasing voltage further. Avoid applying full rated voltage immediately to prevent damage.
Troubleshooting & Maintenance
If the capacitor exhibits excessive leakage current or overheating during reforming, immediately reduce the voltage or discontinue the process as the capacitor may be beyond recovery. Regularly check capacitors for bulging, corrosion, or electrolyte leakage. After reforming, store capacitors in a cool, dry environment to prevent premature deterioration. Periodic reconditioning may be necessary for capacitors in long-term storage or infrequent use.
Safety Reminder
Always exercise caution when working with capacitors and high voltages. Ensure capacitors are fully discharged before handling to avoid electric shock. Use insulated tools and wear protective equipment as needed. Follow all recommended safety procedures outlined in this manual to protect yourself and prevent damage to equipment.
