CIRCUIT DESCRIPTION
In studying the operation of each circuit in voltmeter please refer to Figure 1. the "Block Diagram "· and the Schematic Diagram on the back.
Outline of Operation A signal voltage to be measured. which is input from the INPUT connector. is
passed through the First Attenuator and is converted to a low impedance by the lmpedance Converter. The impedance-conv~rted signal is normalized. or further attenuated in proportion to 1 Vrms fullscale value through the Second and Third Attenuator. The normalized signal is magnified 20-fold by the Main Amplifier and is fed to the Output Amplifier and the Absolute-Mean Value Detctor.
The Output Amplifier magnifies the signal 50-fold and feeds to the OUTPUT connector. The Absolute-Mean Value Detector converts the signal from the Main Amplifier to DC current in proportion to the absolutemean value. The converted signal activates the Meter.
The Attenuator Control encodes the signal led fro m the RANGE selector to generate an Attenuator Control s ignal. This signal controls the First. Second. and Third Attenuators to set the sensitivity corresponding to each range.
The Power Supply feeds to the functional circuits +-5 V DC voltages stabilized by its IC regulator.

OPERATION
Set-up Values in brackets ( j are for the TMV-380, TMV-360 version . 1. Press the POWER pushswitch 2 in. The Power-on indicator 1, a lightemitting diode, will light, indicating that power has been applied.
2. Plug the signal calbes into the INPUT 1 and 2 connectors 4 and 6.
3. Set the CH2 SELECTOR switch 5 to the i ndi vidual side (right position).
4. Set the RANGE-CH 1 & 2 selector 3 and the RANGE-CH2 selector 7 to "100V [300V]". To measure an AC voltage superimposed on a DC voltage, be sure to set the selectors to the positions before connecting the cables to points to be measured. Otherwise, the DC voltage causes a high surge, which could burn voltmeter.
5. Set the GNO ~ODE selector 8 to "GND" (right position).
6. Connect the cables to points to be measure.
7. Turn the selectors 3 and 7 for proper ranges until each Meter pointer switngs over one third of the fullscale.
B. Read the Meter.

(1). Voltage Scales There are two black voltage scales: a scale A graduated 0 to 10 and a scale
B 0 to 3. When the RANGE se l ector 3 is at "1 V", for e xample , the division 10 on the scale A indicates 1 V. At the "300mV" posi ti on, the division 3 on the scale B indicates 300mV. Si milarly, the other RANGE selecto r positions show their full scale values.
(2) . dB Scale In general, the dB values are e x pressed in dB V wh ich is a unit referenced
by 0 dB equal to 1 V. (Note that the TMV-380, TMV-360 version has no dB scale. ) The division 10 at the scale A corre s po nd s t o 0 dB on the red dB scale, whi c h is a voltage ratio s c ale. Sinc e the RANGE s e lector has 12 range positions in steps of 10 dB, the voltage ratio o f 0.3mV to 100 V is 110 dB attenuation. Assume a reference voltage level on th e scale A be 1 V with the RANGE selector at "1 V", a given voltage c an be rea d as low as -70 dB (0.3mV) by t urning the selector downward. Further, as t he sc ale A allows reading to 20 dB ( 0.03mV ) , you can conti nuously measure the voltage ratio as high as -90 d B (0.03m V to 1 V) . The read of -90 dB mean s a si g na l-to-nois e ratio of around 10 dB. Al so , the dB s cale allows continuou s mea su ri ng up to +40 d B (1 to 100 V) by turing the selector upward.
(3). dBm Scale In general, voltmeters have a re f eren c e le vel division of 0 dBm equal to
- 16 -
0.775 V (1mW power) induced across a 600n resistance load , Therefore, the
red dBm scale is available to measure a power level referenced to 0 dBm, with
the impedance of the g1ven power circuit being 600fi pure resistance. Where
measured across specific resistance loads, for example, 10kil
other than
the 600fi load, the levels are sometimes expressed in dBs.
How to Use Remote Control
Availability of the optional Remote Control is one of outstanding features
of Voltmeters.
T~V-3B1R :
To attach the Remot~ Control, remove the blind plate
at the rear of voltmeter. Install and plug the optional conn ec t or into the 16-
pin connector on the PC board. Wire it to the multi - pin connector (plug)
supplied with the option. Also, wire its pins to a RANGE pushs witch or rotary
switch and to a PANEL-REMOTE switch and individual-i nt er lock s witch (toggle
switch, pushswitch or slide switch). These switches allows you to change the
measuring voltage range on your voltmeter from a distance place.
T~V-3B1R type: The measuring range of TMV-381R can be remetely coutrolled by
ACS-017(option ) . The outputs of remote cantrall c onn ector 16 are as table 1
and the input and output or each range are as tabel 2.

APPLICATIONS
The basic use of your voltmeter is to measure sinusoidal wave voltages as an AC voltmeter. In addition , it provides a wide variety of applications as described below.
Amplifier Gain ~easurement Voltmeter is capable of measuring an ampl ifier gain , which is a signal
magnification from point A to B in Figure 6 with a signal generator connected to the amplifier input. If the measured signal levels at poi nts A and B are a and b dB, respectively, then the gain is (b - a) dB .
SIGNAL GENERATOR
Figure 6 - Amplifier Gain ~easurement
Also the method is applicable for measuring an open loop gain of each amplifier circuit with the negative-feedback signal leaves applied . Further, the method can be used for measuring the freq uency responses of given cixcuits by changing the signal generator frequenc y. Voltmeter is capable of directly reading a gain between two points as having two indspendent voltmeters . As an
- 19 -
example, let us calculate the open loop gain {from point A to B) of the negative-feedback amplifier shown in Figure B. Assume that the measured level at point A be +1.5 dB on the -60 dB range of the channel 1 and that of point B -4 dB on the +10 dB range of the channel 2. The gain from point A to B is then (+10 dB -4 dB) - {-60 dB+ 1.5 dB) = 64.5 dB.

Voltage Calculations of Some Special Waveforms An voltmeter of absolute-mean value indication type, reads root-mean-square
values of sinusoidal wave inputs. Also it deflects the pointers in proportion to the abs olutemean value of a given input wave.
If the form factor (=root-mean-square value/absolutemean value} of the input. wave and the crest factor (=peak value/root-mean-square value) are known; then the root-mean-square value and peak value can be calculated as follows.

v ~ 0.9 v.
Root-mean-square value =(Absolute-mean val ue ) x (F orm f a c t or ). Peak value= (Root-mean-square value ) x (C r e s t f ac t or) . For rectangular wanes, their form factor and c res t f ac t or a r e un i t y (1 ).

Wa ye To Better Dual-Channel Voltmeter Operation The two input channels and two meter poin t er s arranged specif i cally in
Voltmeter are most useful for measuring an elec t ron i c equipment having two signal sources.
For example, Voltmeter is far more convenient for measuring stereo left and

CAUTIONS FOR USE
1. Your voltmeter will work just when the POWER switch is pressed in. For accurate measurements, wait around five minutes for warm-up.
2. Avoid placing your voltmeter where magnetic field and electric field are to o strong.
3. The input signal cable other than supplied should be low-capacitance shielded cable, or coaxial cable. For measurements at higher than audio frequencies, terminate the input connetors with 50n or BOOn, resistor.
4. The continuous ma ximum input voltage allowable for your voltmeter is 80 Vrms with the RANGE selector at "-70d8" to "-10dB". Full care should be observed in measuring high voltages.
5. Be careful of a line noise and similar small noises as your voltmeter is a highly sensitive voltmeter ·.
6. Do not leave your meter at any of high temperature and humidity places for a long period of time.
7. As having two channel independent voltmeter, your voltmeter is involved in selection of grounding point on some equipment udner measurement. Set the GND ~ODE switch to "OPEN" and connect the GND post of your voltmeter to a point where noise effect is minimized.
