VACUUM TUBE VOLT METER
Information
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.
