MT235

1. INTRODUCTION
This tester measures all kinds of batteries. The user can choose three
measurement methods according to the battery shape and read the voltage
on the LCD display. Proper use and care of this tester will provide many
years of reliable service.
2. SAFETY INFORMATION
Please read this manual carefully and pay attention to related safe working
standards before using this tester. Protection provided by the instrument will
be impaired if used in a manner not specified by the manufacturer.
WARNING
Ÿ This is not a high voltage test instrument (max. 30V DC). Under no
circumstances should the test leads come in contact with an AC voltage of
any value. Test only batteries for which the designated setting of the
battery selector indicates. Improper use of this battery tester can result in
severe damage to the meter or personal injury.
Ÿ Do not use this tester for measurements within measurement categories
II, III and IV.

5. OPERATION
5.1. TESTING A BATTERY
NOTICE: Always identify the battery polarity before testing.
NOTICE: To avoid excessive drain on the battery under test, do not press
the push button (5) down when using the test leads or short the test leads
across one another when pressing the button (5).
NOTICE: Do not allow the test leads to touch the metal positive and
negative contact points on the tester during any battery test.
1. Set the battery selector (4) to the type of battery you are testing. If the
battery selector (4) is incorrectly positioned, an inaccurate test will result
and may damage the tester and cause excessive drain on the battery.
2. Touch the red test lead (6) to the positive (+) terminal on the battery and
the black test lead (7) to the negative (-) terminal on the battery.
3. Observe the battery condition on the LCD display (1).
4. When testing 9V rectangular batteries, position the positive (+) and
negative (-) battery terminals directly onto the positive and negative
contact points (3 and 2), then observe the battery condition on the LCD
display (1).

5.2. ALTERNATING TESTING METHODS
Depending on the battery type, it may be easier to
use the positive and negative contact points (3 and
2) on the tester instead of touching both test leads
to the positive and negative terminals on a battery.
1. Position the positive (+) terminal of the battery on
the positive contact point (3). Then touch the
black test lead (7) to the negative (-) terminals of
the battery and observe the battery condition on
the LCD display (1).
2. The reverse can be done by positioning the
negative (-) terminal of the battery on the
negative contact point (2) and touching the red
test lead (6) to the positive (+) terminal on the
battery.
5.3. Testing Button Cell Batteries
1. Inserting the battery, negative (-) side up, in the
slot below the push button (5).
2. Press down on the push button (5) to make
contact with the positive and negative terminals on
the battery.
3. Read the battery condition on the LCD display (1).
