SP3 Circuit.

How to use a VOM:


There are many VOM’s on the market so we
will

give you one example.

Simple VOM’s read many things.

DC Volts, AC Volts, Amps, Resistance, Diodes and Transistors.


This one costs $9.95 We
found it on the web.

This is one of the smallest and neatest digital VOM meters we have ever seen. Unlike most small VOM meters, this
meter even measures transistors and current (up to 10
amps). Ranges: DCV 200MV, 2000MV, 20V, 200V, 500V; ACV
200V, 500V; DCA 200uA, 2000uA, 20mA, 200mA, 10A; Resistance 200ohms, 2000ohms, 20Kohm, 200Kohm,
2000Kohm; Diode; Transistor hFE NPN/PNP. This tiny meter is only 3/516" L x 1 3/4" W and fits completely
in your
hand or pocket. Comes with flexible test leads and built in battery. Easy to read high contrast LCD display features
large digits! Once you try this meter, you'll seldom use your full size meter again! Brand new in retail blister package.
Hurry, we

bought out the supplier's entire inventory of these quality meters and they won't be able to supply more of
these for a long time. Orange case (picture shows black case which we no longer sell). G12847



To find
Resistance

of motors, solenoids

or pots, turn the selector to
20K

ohms then

press the test probes to the part. If the

reading is below 2000 then you can turn

the selector down to 200, if below 200,

turn down again or until you get a

full 3 or 4 digit reading.


To test
DC Voltages
, turn the selector to

DC 500V

then press the test probes to

the points you want to test. + to +

-

to
-
. It will show a “

“ on the display if

the wires are backwards.

If the reading is below 200V then you can

turn the selector down to 200V, if below

20V, turn down again. Always start with the

higher setting so you don’t burn out the meter.





To test
Amps
and

mA
, turn

the selector to
10A
, move Red wire from

center socket to one on right (the 10A socket) then press the test probes

to the part.

If the reading is below 002 then you can move Red wire back to center one.

Then turn the selector down to 200mA, if below 20mA
, turn down again.

Always start with the higher setting so you don’t burn out the meter.
