The B & K-Precision Model 1035 Wow & Flutter Meter manual covers the setup and operation of the instrument, including line voltage selection, input signal levels, and measurement standards for wow and flutter in audio equipment. It also provides troubleshooting guidance, such as fuse replacement and instrument repair, to ensure accurate and reliable measurements.
Manual Overview
The B&K-Precision Model 1035 Wow & Flutter Meter is designed for precise measurement of wow and flutter in audio equipment like turntables and tape recorders. It supports four international standards (JIS, NAB, CCIR, DIN) and can operate on multiple line voltages (100, 117, 220, or 240 volts at 50/60 Hz). Troubleshooting involves using the built-in frequency counter and level monitor to ensure proper input signal levels, with the level monitor indicating if the signal is adequate. The device measures wow and flutter from 0.003% to 10% across six ranges, with input sensitivity options from 0.5 mV to 30 V. Calibration is facilitated by internal crystal-controlled oscillators providing stable 3 kHz and 3.15 kHz tones. Error diagnostics are aided by an overflow indicator for frequencies exceeding 9999 Hz. The instrument also features auxiliary outputs for additional analysis with external devices. Board-level guidance includes fuse replacement and case removal for maintenance.
Quick Issues Covered
- Diagnose wow/flutter issues with selectable measurement standards.
- Calibrate using built-in crystal-controlled oscillators for accuracy.
- Error codes for input signal levels via automatic level monitor.
