Tough Against Noise Plus Wide 60V Range
Trying to measure UPS backup batteries while they
are still being used naturally brings about noise com-
Three-rank rating of battery state:

plus fortified circuit design, added with the Averaging
Function to handle batteries that have fluctuating
measurement values no matter how steady you hold
the probe makes the battery tester extra resistant
against the adverse effects of noise.
Assessment is based on a 6-way combination of comparisons against upper and lower
resistance limits and a voltage threshold. Immediately see the judgement result on the
bright LCD and beep on your choice of PASS or WARNING/FAIL.

with the single test pin on each lead has been fortified to
withstand even the toughest use, while a new dual-axis mechanism incorporated in the new

allows the TWO pins in each test lead to move independently. Just in case of breakage,
the pins on both the 9465-10 and the 9772 can be replaced easily on site.

The Advantages of 4-Terminal Measurement
The Quality of Your Test Lead CAN Make a Difference
When measuring certain batteries such as lead-
acid cells, the resulting measurement value may differ
depending on the test leads used to conduct the
measurement. This difference is due to the shape
of the probe tip as well as the dimensions of the
4-terminal test leads used for measurement. However,
despite a difference in value given by different test
leads, it is safe to assume that each specific value
reflects the correct value obtainable by the respective
test leads.
Based on this principle, when diagnosing
battery deterioration in a time series, it is particularly
important to use test leads having the same tip shape
and dimensions in order to maintain measurement
consistency.

phenomenon caused by the difference in distance
between the SOURCE and SENSE pins of the test
leads. This is more significant when the battery
terminal contains a resistance higher than the internal
resistance of the battery under test. The figure on
the right demonstrates how even minute physical
differences between the SOURCE and SENSE pins for
two types of test leads can affect the detected voltage
level of the battery.
