ELECTRONIC VACUUM TUBE VOLTMETER KIT FEATURES • Push-Pull Balanced-Bridge Meter Circuit Assures Accuracy and Protection • 11-Megohm Input Resistance Minimizes Circuit Loading—Gives True Readings • Measures BOTH Peak-to-Peak and RMS AC Voltages in 7 Ranges Each • Single Zero-Adjustment Control for all Functions and all Ranges • Positive and Negative DC Function Switch Positions Eliminate Lead Reversal • Zero-Center Scale for Alignment of TV and FM Discriminator Circuits • Transformer-Type Power Supply for Line Isolation and Operating Safety • Calibrates Without Removing Cabinet • Film-Type 1% Precision Resistors Outstanding in both performance and value .... offering all the quality that years of experience and research in instrument development can provide . . . having all the modern, advanced features needed for all-around efficiency of electronics servicing . . . this is your Knight-Kit VTVM. Provides entirely electronic, direct-reading measurement of AC voltage (BOTH Peak-to-Peak and RMS values), DC voltage, decibels and resistance on a rugged, highly legible, two-color 4y2" fu11-view meter. Invaluable for signal tracing, for alignment, for voltage and resistance measurements in AM/FM radios or tuners, television and hi-fi sets, for checking frequency response, for continuity tests, and for servicing electrical equipment. Feature highlights include: film-type 1% precision resistors and multipliers; low-leakage function and range switches; finest-grade printed circuit board; 3 separate test leads for AC-Ohms, DC, and Common; heavy-gauge steel case with rugged panel; pilot light; transformer-operated power supply for line isolation and safety; standard 1%-volt “C" battery; 200-microamp meter movement; carrying strap; and premium-quality parts. Circuitry boasts: push-pull balanced-bridge for maximum accuracy and meter protection; DC polarity-reversing switching; 11-megohm input resistance to reduce circuit loading to a minimum and assure true readings; zero-center scale; direct-reading decibel scale; highly sensitive DC amplifier to allow resistance measurements as high as 1000 megohms using only the 1>£ volt battery — eliminating danger to delicate apparatus under test; single zero-adjustment control for all functions and ranges; and calibration without removing internal chassis from cabinet.
