The voltage of 2 volts cells must be recorded to 3 digits. Ex: 2.122 instead of 2.12.
The Cell condition Report in the Analysis section of the Review page compares cell voltages. Therefore if a cell measuring 2.121 is entered as 2.12 and a cell measuring 2.129 is entered as 2.12 the difference is 0 and no number will be plotted on the Cell Condition Report chart.
While the actual difference in the example above is 0.008 the number will be plotted on the chart providing a very accurate representation of the relationship between the 2 cells.
Similarly the voltage of 6, 8 and 12 volt batteries should be entered to the maximum number of digits that the voltmeter displays.
