Battery Tester  (220-0032A)        Installation        Faxback Doc. # 7037

Your Radio Shack Battery Tester is a sensitive, accurate tester for
checking batteries under designed load conditions.  You can test standard
carbon zinc, alkaline, mercury, silver oxide, lithium, and nickel cadmium
batteries.

1.  Set the recessed index mark of the rand switch adjacent to the marked
    voltage and type of the battery you want to check.

For example, to check a 1.5V C-type battery, move the switch opposite the
label 1.5V AA C D.  To check a 9V rectangular battery, position the switch
opposite 9V.  If you want to check a mercury, silver oxide or alkaline
button cell, move the switch to BUTTON CELL 1.5V.  If the button cell is
a lithium type, position the switch to LITHIUM 3V.

To test 1.25V nickel-cadmium batteries, use the 1.5V AA C D position and
read the lower nickel-cadmium scale.

The current figure within the range on the meter is the load current drain
placed on the battery during checking.

CAUTION:  If you position the switch improperly, you cannot obtain an
          accurate battery check.  In addition, you might damage the
          tester.

2.  Touch the red probe tip to the positive battery terminal and the black
    probe tip to the negative battery terminal.

CAUTION:  Always identify battery polarity correctly before testing.

USE THE FOLLOWING HANDLING METHODS FOR MOST BATTERIES:

-Position the negative side of the battery against the negative post and
 touch the red probe tip to the positive terminal of the battery.

-To check a 9V rectangular battery, position the battery terminals so that
 they make contact with the 9V positive and negative posts on the battery
 tester.

-To check a button type battery, insert the battery into the recess at the
 right side of the test with the negative terminal of the battery up.
 Then, press the brown switch down.

CAUTION:  To avoid damage to the battery under test:

-Do not push the brown switch down when using the probe tips for testing
 a button type battery.

-Do not allow the red probe tip to contact the black probe or negative post
 when you use the 9V rectangular or button type battery terminals.

3.  Read the scale to determine the battery condition.

-Use the upper REGULAR scale for measuring regular carbon-zinc and
 alkaline batteries.  Use the center BUTTON CELL-LITHIUM scale for
 measuring mercury, silver oxide, alkaline and lithium button cell
 batteries.  Use the lower NICKEL CADMIUM scale for measuring rechargeable
 nickel cadmium batteries.

-If reading is in the red REPLACE or RECHARGE zone, replace or recharge
 the battery.  IF the reading is in the green GOOD zone, the battery has
 considerable life.  IF the reading is on the oblique lines in the REGULAR
 scale, this indicates that battery strength is marginal.  consider
 replace the battery.

NOTE:  Your tester is designed to check almost all electronic and
       flashlight batteries.  It is NOT designed to test 6 to 12
       volt lantern, motorcycle, or marine batteries.

If the needle fails to align with the black dot in the upper left hand
corner, you can adjust the zero position of the needle.  Insert a flat
bladed screwdriver in the zero-adjustment screw.  Rotate the screw so that
the needle aligns with the black dot at the extreme left end of the top
scale.
