DESCRIPTION

Ideal for use where measurements must not appreciably disturb
the circuit being tested, the Model Sears 5205 features high
50,000 ohms/volt DC and 10,000 ohms/volt AC sensitivities, on
one set of voltage ranges. A second group of voltage ranges with

- sensitivities of 25,000 ohms/volt DC and 5,000 ohms/volt AC
has been designed into this instrument. Because of the avail-
ability of 12 DC voltage ranges and8AC voltage ranges, more

accurate readings are possible with this instrument than with
an ordinary VOM. Also included are ten DC current ranges and
five resistance ranges to assure precise current and resistance
indications. In conjunction with a power supply, the Model
Sears 5205 can be used to measure capacitance and inductance.
Special circuitry has been included to protect the meter move-

ment against accidental overload. A mi rror arc has been pro-
vided to help eliminate parallax errors from readings. A con-
venient carrying handle built onto the case can also be used to

Position the meter for easy reading. The Sears 5205 is a quality

product in both performance and appearance.

HOW TO INSTALL BATTERIES

Remove the screws in the rear cover of the case- Lift the back of

the case off the front section. Note the orientation of the bat-
teries in their compartments. When replacing the" AA"cell, the
positive

(+)

the case closest to the top. Be sure that the contact at each end

of the compartment makes a good connection with the metallic
battery terminal at its positive end and with the metallic
portion of the battery case at its negative end.

The 9 volt battery must be so oriented that its plus terminal is at
the connector marked
its minus terminal is at the connector marked "-". Slide the
battery straight down into its compartment, being sure that it is
held firmly.

end of the cell should be at the end so indicated on

in the case (closest to the side) and

Carefully replace the back onto the front of the case. Tighten
the screws. Do not tighten them excessively, or you will strip
the threads in the case.

CONTROLS AND JACKS

RANGE switch: Select factor and range to be measured.

V-fl.-A slide switch: Meter pointer indicates DC or AC voltage

or DC cu rrent on range selected by RANGE switch, when
slide switch is set to the V-fl.-A position. Meter pointer
indicates one half the voltage or current on range selected
by RANGE switch, when slide switch is set to the V-A/2
position,

OHMS ADJ. control: Use to set pointer to 0 (extrema right on

meter scales) on uppermost ohmmeter scale in an OHMS

setting of the RANGE switch, when test leads are in contact
with each other.

Mechanical adjust: Adjustable screw on meter movement to

set pointer to zero when leads are in contact with each other
in a DCV setting of the RANGE switch.

COM jack: Plug-in connection for black, negative test lead.

Ef>V-fl.-A jack: Plug-in connection for red, positive test lead,

1000V DC jack: Plug in connection for red test lead when

measuring DC to 1,000 volts. RANGE switch must be set to
the 250&1000 DCV position and V-fl.-A slide switch must
be set to the V-fl.-A position. Voltage will be 1/2 that noted
on meter (to 500 volts) if the V-rl.-A slide switch is set in the

V-A/2 position.

BAT_ jack: Plug-in connection for red, positive test lead when

testing batteries,
RANGE switch must be set to BAT. CHECK and slide
switch must be set to the wanted position.

OPERATING PROCEDURE

PRELIMINARY ADJUSTMENTS

1. Check the mechanical adjustable screw setting as follows:
a. Place the Sears 5205 tester flat on a bench:
b. Set the RANGE switch to 2.5 DCV. The V-fl.-A slide

switch can be set in either position.
c. Connect one test lead to the other,
d, Note if the meter pointer indicates exactly 0 at the

extreme left end of the black scales.
e. If it does not read 0, turn the screw on the meter move-

ments slowly until the proper 0 reading is realized.

2. Check the batteries as follows:

a

Place one test lead in contact with the other.
b. Set the RANGE switch to R x 1.
c. Turn the OHMS ADJ_ control until you fi nd the position

where the pointer indicates the full scale 0 on the OHMS
scale. If this adjustment cannot be made, replace the 1.5
volt size" AA" cell.

d. Now set the RANGE switch to R x 10K.
e. Turn the OHMS ADJ_ control until you find the position

where the meter pointer indicates full scale 0 on the

OHMS scale .. If this adjustment cannot be made, replace

the 9-volt battery.

OPERATING SUGGESTIONS

1. Meter ranges are noted on the front panel, arou nd the
RANGE switch. DC and AC voltage as well as DC current
ranges selected through use of the knob on the RANGE

switch are those shown at this switch only when the V-fl.-A
slide switch is in the V-fl.-A position. In this case, the

sensitivity of the voltmeter is 25,000 ohms/volt DC and
