The manual for the Sencore LC77 calibration procedure provides detailed instructions for accessing the device's interior, the equipment required for calibration, and step-by-step guidance on calibrating various functions such as capacitance, leakage, dielectric absorption, ESR, and inductance. It also includes troubleshooting steps to ensure accurate readings and adjustments, emphasizing the importance of using high-accuracy standards and allowing a warm-up period before calibration.
Manual Overview
The Sencore LC77 calibration procedure is designed for qualified technicians to ensure accurate performance of the device. To access the internal components for recalibration, the unit must be unplugged, and the case removed by unscrewing and gently pulling it apart. Calibration requires high-accuracy capacitance, inductance, and resistance sources, as well as a digital voltmeter, adjustable DC voltage source, 100 Hertz sine wave source, and oscilloscope. The power supply calibration involves adjusting specific resistors on the leakage supply and main boards to achieve precise voltage readings. Capacitance calibration requires connecting known capacitors and adjusting resistors to match specified values. Leakage calibration involves setting resistors to ensure accurate current readings at various voltages. Dielectric absorption and ESR calibrations require adjusting resistors to achieve specified readings with test resistors. Inductance calibration uses standard inductors to adjust controls for accurate range calibration. Each calibration step involves precise adjustments and repeated verification to ensure the LC77 meets its operational specifications.
