Test Capability; Measurements; Test Range; Data Storage - Midtronics Celltron Ultra Instruction Manual

Chapter 1: Introduction
The analyzer features a backlit graphical LCD, a digital multimeter, and an SD (Secure Digital) fl ash
memory card for data storage and transfer to a PC. The analyzer software includes an icon-based
menu and pre-loaded data on over 200 battery models to expedite testing and record-keeping.

Test capability

The Celltron ULTRA tests lead-acid batteries that are 2, 4, 6, 8, 10, 12, 14, and 16 V. The analyzer
can test batteries providing power to a load (in service) or not providing power (not in service).

Measurements

The analyzer measures the status of a jar in voltages and conductance values. It displays conduc-
tance values in mhos ( ). Ampere hours (Ah) are a typical measurement of jar capacity; however,
they are diffi cult to measure without knowing the load to which the jars supply power. Midtronics
recommends that you compare test results to a conductance reference value. For more information
about determining a reference value, refer to Chapter 3.

Test range

The analyzer has an operating range of 0 to 20,000 S. This range includes jars that have about 5 to
6000 Ah of reserve capacity .

Data storage

The analyzer's SD memory card can store 480 test results per string for as many as 500 strings.
Tables 1 and 2 show the maximum number of jars you can test depending on the number of jar posts
and straps that you test.
