The Seco model 208 VTVM is especially designed for the electronic technician. It has a sloping front meter which is easy to read and provides 7 a-c, 7 d-c and 7 ordinary OHMS ranges -- PLUS --a special RETMA (Electronic Industries Association) ohms scale for extra fast checking of these coded values ,^nd their tolerance limits. The function selector switch is a specially designed "shift lever" which allows change of function without looking. The two most often used functions, PLUS D-C and OHMS are at the two extremities of the switch. The color of the test lead to be used is also indicated opposite each function. The input resistance on alld-c ranges is 11 megohms, whi,ch is high enough to prevent loading of most circuits under test. A one-megohm isolation resistor is incorporated in the d-c test Probe. An additional feature, exclusive with the Seco 208, is a separate terminal for connecting a "high voltage” Probe which extends the d-c voltage range from 1500V to 50,000V, without disconnecting the regular probes and provision is made for measuring a-c line volts by turning the OFF-ON switch to LINE VOLTAGE. Facilities that increase the versatility and ease of operation include zero-center indication for measuring minus and plus d-c volts and measuring tolerance of RETMA coded resistors.
