G E N E R A L
The Model V T - 1 7 5 is dual-channel electronic voltmeter
sets having t w o independent A C voltmeters in a single
cabinet. Two-pointer meter a l l o w s easy dual measurements
and inter-channel comparisons.
M O D E L V T - 1 7 5 is wideband, high sensitive voltmeter
use anywhere voltage measurements are made, w i t h a
remote control unit. The easy-to-use voltmeter provides
frequency response as wide as 5Hz to 1 M H z , measurable
range f r o m 1mV to 300V, and input impedance of
1 0 M O .

a .
T w o power source c i r c u i t s , positive and negative,
are provided for very stable D C bias and recover
f r o m any overload in a very short time.
b.
Small-sized compact construction is easy to c a r r y
for
and large-sized two-pointer
c.
Four-scale dial plate and red and black pointers
a l l o w quick, and accurate voltage reading.
d.
Number of adjusting t r i m m e r s are minimized w i t h
a m p l i f i e r s t h a t are precisely calculated in open loop
gains and are negative feedbacked through metal-
f i l m resistors a s accurate as 1%
A m p l i f i e r characteristics therefore are f r o m secular
change.
e.
Input impedance is as high a s 10 M O on a l l ranges
and its parallel capacitance less than 45 p F
f.
Indirect attenuator switching by relay and F E T
(field-effect t r a n s i s t o r ) switch provides higher
reliability, signal-to-noise r a t i o , and inter-channel
crosstalk than most previous direct method of rotary
s w i t c h .
