(i) Measuring Single Cells
The meter is capable of measuring cells as small as 100mAh but the
4 wire Kelvin measurement, and therefore the Lipotool calculation,
cannot be made because there is no balance connector to plug the
search lead into. In any case, such small cells have IR values outside
of the Cell Mode measurement range 0f 0 35milliohms and can
therefore only be measured in Pack mode where the range is 0
250millioums. This means that the additional resistance of the leads
and connector are included in the measurement figure. You will need
a multi plug charger adapter lead to convert from the ‘T’ connector
to any small single cell connector used on small single cells. These
are available for at minimal cost on line or from most serious hobby
stores.
The small micro connectors used on very small cells are very
variable in their contact resistance and it is recommended that you
take several readings and use the lowest as several insertions will
help to remove the oxide film on contacts. Alternatively use a
contact cleaner.
REMEMBER: FOR ACCURATE RESULTS YOU MUST
TAKE ESR AND CURRENT READINGS AT 22 - 25C (72 -
77C)
