Chapter 1: Description
The Celltron Advanced is a stationary battery string analyzer that measures the conductance and
voltage of individual or strings of single cell (2 V) through six cell (12 V) stationary, lead-acid
jars to help identify those that
• Are good
• Are serviceable
• Need to be replaced
Specifications
Measurements
The analyzer measures the status of a jar in voltages and conductance values. It displays
conductance values in siemens (S). Ampere hours (Ah) are a typical measurement of jar
capacity, however, they are difficult to measure without knowing the load the jars supply
power to.
Midtronics recommends that you use a reference value to compare the conductance value to the
test results. A reference value is a typical conductance value for the type of jars you are testing.
For more information about determining a reference value, refer to "Chapter 2: Pre-testing."
Test capability
The analyzer tests jars that are providing power to a load or (in-service) or those that are not
providing power (not in-service).
Test range
The analyzer has an operating range of 0–20000 S. This range includes jars that have about
5–6000 Ah of reserve capacity
Data storage
The analyzer can store 480 test results for a string at one time. Tables 4 and 5 show the number
of jars you can test depending on the number of jar posts and straps that you test.
