1. G E N E R A L

Y o u r K E N W O O D ' S Electronic V o l t m e t e r , Model V T - 1 7 1 ,
r"VT-171EJ , is a voltmeter
indication type capable of measuring A C voltages
f r o m I m V T S O O ^ V J to 300V r 100VJ in the frequency
range as wide as 5Hz to
value scales. Y o u r V T - 1 7 1 T V T - 1 7 1 E J is available in
v a r i e t y of applications as it is highly sensitive and responds
accurately to given voltages in such a wide frequency
range. F o r use on production

a . Dual power differential
entire circuit provide a high reliability and good
characteristic of restoration f r o m possible s a t u r a t i o n
due to excessive inputs.
b. A large-sized Taut-band meter has a high s e n s i t i v i t y
and reliability.
c. The number of adjusting t r i m m e r s are minimized
w i t h the use of the a m p l i f i e r s which are precisely
calculated in the open loop gains and are negative-
biased through metal-film
The a m p l i f i e r characteristics, therefore, are free f r o m
any secular change.
d. The input resistance is a s high as 1 0 M O in a l l
ranges and its parallel capacitance is 4 5 p F or lower.
e. The meter scales are graduated in the root-mean-
square values for sinusolidal waves. A l s o , the meter
has a d B and dBm scales convenient for measuring
relative values.
f. The output t e r m i n a l
to use as a high-gain, wide-band
input a m p l i f i e r s used in the
resistors as accurate as 1%.
