4.1.4 Dual Testing
If the user is testing batteries with (4), four terminals and the batteries are
connected in series.
4.1.5 Triple Testing
If the user is testing batteries with (6) six terminals and the batteries are
connected in series or if (3) three positive terminals are connected
together and the (3) negatives are connected together.
4.1.6 Quad Testing
If the user is testing batteries when each negative of (3) negative
terminals are connected to each positive of the (3) positive terminals of
the next battery.
4.1.7 Combined Testing
Combined testing is done in one-step using only two leads and does not
require the use of the third intercell lead. Connect the positive lead to the
positive post of the cell being tested. Connect the negative lead to the
positive post of the next cell. The reading combines the cell resistance/Rc
plus the intercell resistance/Ric. Using Combined, no
values are
displayed for Ric1 to Ric4. Combined is faster than Computed, but does
not separately indicate cell and intercell resistance values, whereas
Computed does.
NOTE:
The combined mode of testing can be used on the last cell
of a series.
4.1.8 Computed Testing
Computed testing requires two steps using two leads. First, attach the
leads to the positive and negative terminals of a jar connected to a second
jar via an intercell connection, then perform the resistance test. Then,
move the negative lead to the positive terminal (with the intercell
connection) of the second jar and perform the resistance test. The CRT
subtracts the lower Rc and displays two resistance readings: the cell Rc
and the computed intercell Ric. Use Computed to determine if a problem
is in the cell or in the intercell connection. Refer to Application Note
CC–002–A for connection diagrams located in the CRT User's Guide or
on the website.
