How To Use A Multimeter

What is a multimeter? and how to use it?
 • A multimeter is a devise used to measure voltage, resistanceand current in electronics & electrical equipment
• It is also used to test continuity between to 2 points to verify ifthere is any breaks in circuit or line
• There are two types of multimeter Analog & Digital– Analog has a needle style gauge – Digital has a LCD display (Referenced during this PPT) Page 3 SwitchedManually switchbetween ranges to getmost accurate reading. Auto RangeSwitches betweenranges automaticallyfor best reading.

There are 2 styles of multimeters

SwitchedManually switchbetween ranges to getmost accurate reading. and Auto RangeSwitches betweenranges automaticallyfor best reading. Both of thesestyles work thesame.

SCHEMATIC TONE CONTROL AND SUBWOOFER OUT



PT2350 is a tone control subwoofer cross-over low pass filter chip utilizing CMOS Technology. It features a tone control range of + 10dB (50Hz, 4 KHz) and subwoofer low pass filter of the second order Sallen Key Design. The roll-off point can be adjusted by changing the value of the external capacitor. Pin assignments and application circuits are optimized for easy PCB Layout and cost saving advantages.



CMOS Technology



2-Channel Input

3-Channel Output (Including 1 stereo Output and Subwoofer Output)

Low Total Harmonic Distortion (THD<0.01%, Subwoofer THD<0.2%)

High S/N Ratio (S/N Ratio <-87dB, A-weighting)

Least External Components

Adjustment of Frequency response by changing the value of the external component

Single Power Supply: 3 to 8.5 Volts

Available in 20 pins, DIP or SO Package

Frequency response of tone control unit is flat between 20 Hz … 20 kHz when treble and bass pots are in middle.

Overall gain is approx. 6 dB when treble and bass pots are in middle.

Treble and bass tone control range is approx. 10 dB (50Hz / 4 kHz) with given component values.

Subwoofer cut off frequency can be adjusted by bass potentiometer… with component values as listed above it is as follows : bass pot in minimum (left) -3dB point, 240 Hz / -12dB 450 Hz, bass pot (middle) -3dB point 100 Hz /-12dB 200 Hz, bass pot maximum (right) -3dB point 60 Hz / -12dB 120 Hz.

Distortion was < 0.1 % when input level was < 0.3V rms.

There is no balance adjustment potentiometer in this application, if you need balance, you must add it separately in this device.
