G E N E R A L
The K E N W O O D E l e c t r o n i c Voltmeter V T - 1 7 3 is an
absolute-mean value indication type a u t o m a t i c electronic
voltmeter which can measure A C voltage ranging
10Hz to 1MHz on the root-mean-square value scale.
It has a wide f u l l scale ranges covering f r o m
300V

a .
Dual power differential input a m p l i f i e r s used in the
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 resistors as accurate as 1 %.
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 10 M i l
ranges and its parallel capacitance is 45pF 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 d B m scales convenient for measuring
relative values.
