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.

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.
