3. OPERATION
3.1 Measurement Preparation
3.1.1 Main Unit Structure and Operation
Below are the pictures for the main unit:
Back Side

Operation of touch-screen
Click on each menu to highlight it and click it again to carry out each function. Click “Back” to return to
the upper menu and click “Home” to return to the starting screen.
Operation of keyboard:
Keyboard operation has the same effect with touch-screen operation. Press each arrow key “←”, “→”,
“↑” and “↓” to highlight each menu and press Enter to activate it. And key Esc is for going back to
upper menu.
3.1.2 Wire Connection
Before measurement, please first connect the testing clip with main unit and fix the screw like Fig
3.1.2.1. Then clamp the black clip with the negative polar of battery and the red clip with positive.
NOTE:
1) To enhance the measurement accuracy, please try to clamp the clips around the posts of
battery. Rust or any insulating material (e.g. glue) around the posts will increase the
resistance. Therefore, please try to avoid these causes before connecting the clips.
2) Measurement of PITE 3918 is based on 4-point measurement. Each clamp has two metal
points that are connected with the battery posts during measurement. This is same to the pin
type probe. So each time when you use the pin probe for measurement, make sure that all the
four pins on the pin probe should be connected with the battery posts well.

3.1.4 About Reference Values
PITE 3915 has pre-installed reference conductance for some common battery types. These values are
average conductance values got from samples of strong battery strings similar in condition and age of
usage. Generally, a sample of 30 new or healthy batteries are tested to obtain a value representative
of a new online battery 90 days after installation. By comparison, the differences between test results
and reference values will help you determine the string capacity and health status for further solutions.
Differences may reflect how a string was treated, installed, or maintained.
How to specify your reference values?
Reference values in PITE 3915 menu may not universally fit the batteries that you are testing.
Therefore, you are recommended to specify your own reference values. You have the following
options to set your reference value:
A. Consult to your document from battery manufacturer for the reference values for the batteries that
you are testing.
B. Test the batteries in the string and use the lowest conductance under correct way of test for
reference value. For cells ranking in the string, please refer to String summary in 3.3 Data
Management.

PITE 3915 Battery Tester User Manual

C. Use the average conductance of the string as reference value. This is only used for measurement
of battery string. For detailed setting, please refer to “Set average value as reference” in section
3.2.2 Test for Battery String.
Indications of Battery Condition
Below is the definition of the testing result for battery and battery string.

NOTE: You could also see reference values in Appendix of this manual.
3.2 Measurement
3.2.1 Test for Single Cell
This is for testing single cell. To do this, you will need to set the parameter of the cell before
measurement. If you have several blocks of batteries of the same rating (e.g. 2V, 100Ah), you are
suggested to use “string test” (see 3.2.2) which will be much more time-saving and convenient for data
management in PITE PC software.
Select “Test Cell” in the menu to enter the screen for parameter setting. (See Fig 3.2.1.1).
Fig 3.2.1.1 Fig 3.2.1.2
Use main unit keyboard or mini keyboard on screen for number input.
Totally there are 5 options for single cell voltage: 1.2V, 2V, 6V, 12V and self-defined. Please click the
option of “Voltage” to view each one (Fig 3.2.1.1). As voltage changes, cell rating will be changed
accordingly. Click the box or use arrow keys to select the cell type that you will test. Reference
resistance will be changed to fit each cell type.

PITE 3915 Battery Tester User Manual

Cell number is self-defined to distinguish from each other. This could be viewed in data management.
After the setting, click the button Start at right bottom to carry out the test.
Testing result will display in seconds like Fig 3.2.1.7. If you need to retest it, click the button Retest.
Click Save (in Fig 3.2.1.2) to save the testing result, or disconnect the testing clips from battery and
testing result will be automatically saved.
NOTE: As mentioned in 3.1.2 Wire connection, testing result may vary a little due to different way of
connection between testing clips and battery posts. Therefore, if testing result varies in different time,
please refer to the lower value.
Specify Battery Type & Reference Value
If you could not find the exact type of battery that you want to test, or you want to specify your own
reference resistance, you could self-define the parameter.
1) Specify battery type
If you have battery that has non-standard voltage type (e.g. 4V 100Ah), you could add this type. To do
this, please select “Defined” in the box of “Voltage”, then click Set Para at the bottom, input the
parameters required and click Add to save the setting (e.g. refer to images from Fig 3.2.1.3 to Fig
3.2.1.5). Maximally you could set 10 different voltage types.
2) Specify reference value
If you would like to set different resistance reference or cell type under the same battery voltage,
please first select voltage rating and then click the button Set Para to add these information.
Maximally you could add 10 different cell types under each battery voltage. Screen in Fig 3.2.1.6 and
Fig 3.2.1.7 are for your reference.
