Information:

GENERAL The B & K model 375 Dynamatic VTVM enables the user to make measurements with a degree of speed and accuracy that far surpasses conventional instruments. Each voltage, resistance and current range has a separately calibrated scale that automatically appears as the range switch is rotated. The instrument is direct reading since only the one correct scale is visible to the operator. Even peak to peak voltages are direct reading and do not require special interpretation. The iridescent knife-edge pointer and anti-parallax mirror makes it easy for the user to obtain precise measurements. Illuminated scales eliminate reflections and permit readings even under poor lighting conditions. A sturdy combination Probe with built in switch is used for all voltage and resistance measurements. Separate front panel current jacks are isolated from the VTVM circuitry for safety and convenience. The high input resistance (11 megohms) on all D. C. Voltage ranges minimize circuit loading when measurements are made from high resistance sources. The 1 megohm resistor built into the combination Probe prevents cable capacitance from shunting any A. C. or R. F. signal when measuring D. C. voltage. An electronic bridge circuit protects the sensitive meter movement from any damage during accidental voltage overloads on all A. C. and D. C. voltage ranges. The VTVM incorporates a detector which is accurate for complex as well as sinusoidal voltages. A separate crystal diode R. F. Probe is available to extend the range of A. C. measurements to 250 M.C. A unique combination swivel stand and carrying handle provide the utmost in operator convenience. Any viewing and operating angle can be obtained regardless of the location of the instrument.
