With switch II in position 1, the meter measures the root-
mean-square value of sinusoidal voltage, and in position 29
the effective value of noise voltage. Via a voltage divider
the A.C. voltage is applied to the wide-band amplifier and
then to the detector. From the detector output the rectified
voltage is fed to the indicator. With switch n in positions 3
or 4, the meter functions as a D.C. voltmeter.
With switch n in position 3, the meter measures positive
D.C. voltage relative to the "earth", whereas with switch ii
in position 4, the meter measures negative D.C. voltage
relative to the "earth".
A D.C. source voltage is applied to the D.C. voltage
divider and then to the measuring bridge, into the diagonal
of which an indicator is out in.
The circuit is provided with a limiter which protects the
Indicator from overloading in case the measuring range on
the divider is set wrong.
Both the A.C. and D.C. voltages are read off with the aid
of the same indicator scales.
4. DESCRIPTION OF KEY CIRCUIT DIAGRAM
(See Diagram 1(6.294.0060x3)
(A) A.C. Voltmeter
The A.C. voltmeter employs valves 6H1n (13), 622n (21, 31)
and 6X2II (38).
There is a stage with a cathode load (valve 13) at the
electronic voltmeter input. A low input capacitance of the
stage ensures a constant high input resistance up to the
frequency of 100 Ko/s.
Both triodes of valve 614111 (13) are oonnected in parallel
In order to decrease its inner resistance, whioh is required
to ensure linearity of the stage amplitude obaraoteristio
within 100 V. This excludes a necessity to use a high-ohmic
divider at the voltmeter input which might lead to a consi-
derable increase of input oapaoltanoe and, consequently, to
the narrowing of the frequency range. Tho voltage divider
reuifitorkl (5 to 12) serve as a stage cathode load.

select one or the required rans.
The circuit eploys a low?ohmic voltage divider (30 kil?
ohms) which makes its frequency characteristic almost inde?
peaJoat of the input capacitance of the subsequent stage.
The wide?band voltage amplifier employs valves oimn
(22 and 31) in accorrR'nee with the ordinary rheostat circuit
with a negative feedback dependent on values of resistors 23.
24, 37 and capacitor 33.
The feedback provides for the linearity of the frequency
characteristic of the amplifier and stability of its opera?
tion.
Capacitor 33 is designed for compensating the frequency
characteristic at the hizh -frequencies. Potentiometer 40 is
intended to set the electronic?voltmeter zero.
To make it possible to measure the sinusoidal and aoise
voltages at one scale, potentiometer 80 is connected in
parallel with the indicator for measuring the sinusoidal
voltage. To make the indicator time constant equal to 4 to
6 sec., Which is required for measuring the noise voltage,
charging capacitor 78 is used. Menthe D.C. voltage is
measured, capacitor 78 is discharged through resistor 77.
Capacitor 75 serves to provide for required inertia of the
indicator pointer in the process of measuring the sinusoidal
voltages.
(B) D.C. Voltmeter
The D.C. voltmeter circuit is a bridge consisting of four
arw3. Instrument M-24, serving as an electronic?voltmeter
indicator, is cut into the bridge diagonal.
Two arms of the bridge are triodes of valve 61111I (68),
whereas the third and fourth arms are resistors 70 and 71
interconnected by potentiometer 69 which is designed for set?
ting the electronic?voltmeter zero.
Diode 64 serves to limit the current flowing through the
instrument when a voltage exceeding 4 V is applied to the
leit?hand triode grid of valve 68. The limiting proceeds in
the following way: the anode:, of valvc 64 are supplied with
6
ST4T.PF.

-3.8 V relative to the cathodes, and the valve is out off.
When the voltage at the grid of valve 68 exceeds the value
11.8 V (depending on the polarity of the voltage to be
measured, the left-hand or right-hand diode is operative),
the current begins to flow through the diode. As a result,
the voltage drops across resistor 63 which prevents further
increase of the voltage across the grid of valve 68.
A voltage divider employing resistors 56 to 62 is connect-
ed to the voltmeter input.
The total resistanoe of the divider is equal to 10 meg-
ohms. Resistor 63 decreases the influence of the variation
of the grid-leak resistor of valve 68 at different positions
of switch MEASUREMENT RANGES 15, thus nearly excluding the
necessity to compensate the instrument zero when switching
over from one scale to another.
Besides, resistor 63 and capacitor 66 serve as a filter
protecting the grid circuit of valve 68 from possible
variable components of the voltage when measuring the D.C.
voltages, as it may take place, for instanoe, in the process
of measuring the anode voltage of the operative amplifier.
Potentiometer 67 is designed to adjust the circuit
sensitivity.
The measurement ranges of both voltmeters are switched
over with the aid of switch 15. Selector switch KIND OF
MEASUREMENT (MA 143MEPEliffial) 76 serves to select the required
kind of measurements.
The circuit is supplied by the A.C. mains of 220 or 127 V,
which is achieved by switching over correspondingly power-
transformer 49 primary winding with the aid of fuses 51 and
The rectifier employs a full-wave circuit with valve 48.
A filter composed of choke 45 and capacitors 44, 46, 47
serves to smooth pulsations.
The A.C. voltmeter supply voltage is not stabilized, since
a sufficient stability of the circuit is ensured at the
expense of a deep negative feedback.

5. DESIGN
(See Figs 2 and 3)
Al]. elements of the meter are mounted on the chassis
consisting of two main plates: a vertical plate and a horizon?
tal one fastened together. At the same time, the vertical
plate serves as a front panel of the meter and carries all
controls. There are two handles on the panel which are used
to remove the chassis out of the housing and to protect
simultaneously the controls from damage when the meter is
plaoed with its front panel downwards for repair.
The meter chassis carries all elements of the circuit.
The indicator is arranged on the meter front panel and is
made shockproof by means of a rubber gasket. All transfor?
mers, chokes and wire?wound resistors are impregnated with
speoial lacquer to prevent moisture from penetrating inside
the windings. All soldered joints are painted for the purpose
of checking. The Chassis is inserted into the housing and
fastened by four screws. For the purpose of conveniently
carrying the meter, its casing is made in the form of a
suitcase with a detachable lid covering the front panel.
The inside of the meter lid is provided with clamps which
serve for arrangement of a supply cable and two measuring
cables. On the rear side of the chassis, under the flap, are
mounted: a supply-block and two fuses for 127 and 220 V.
This construction allows to change over the mains voltages
and to replace the fuses without removing the meter casing.
The walls of the casing are provided with louvers for better
cooling of internal elements. The meter is provided with a
cover to prevent the former from damage and penetration of
moisture during transportation.

tion.
