General Description

The CRT-300 Cellcorder battery cell voltage and resistance tester features a
Smart Media



memory card, infrared communication, graphical reflective

LCD display, and newly designed cables and clamps. The Cellcorder reads
single cells and multicell modules, and displays and records cell float
voltage, internal cell resistance, and intercell connection resistance. A
compatible hydrometer can transfer specific gravity and temperature data via
the IR port.

The self-contained CRT-300 Cellcorder is comprised of a microprocessor,
load resistor, display, and rechargeable battery. Voltmeter probes and a three
clip resistance set are provided; optional test leads are available from Albér.

The CRT-300 functions well even in high noise environments, without the
need to disconnect the battery from service. A 60 amp DC load (on 2V cells)
is used to calculate internal cell resistance and intercell resistance. Circuitry
rejects the 50Hz/60Hz ripple and associated harmonics often troublesome to
AC-based impedance and conductance meters.

The CRT-300 ships with an 8M memory card, USB memory card
reader/writer, resistance and voltage test leads, carrying case, charger
module, and Battery Analysis System (BAS) software. An optional thermal
printer is available.

Data Memory and Communication

- The removable memory card stores a

large amount of data in both CRT-300 .CDF and Excel



.CSV file formats.

The memory card or IR port transfers readings to a computer for analysis
and report generation.

System Display

- The high contrast, 128 x 64 pixel, backlit graphical display

shows menus, warnings, and test results.

Power

- The CRT-300 is powered by a lithium ion rechargeable battery. It

does not operate on AC power. A fully charged unit can test for seven hours.
Isolated operation helps ensure safety. A charger module is included.

Float Voltage Readings

- The CRT-300 measures the voltage applied

during full float operation. The voltage range covers all cells or modules up
to 20 volts. Accuracy of readings is to four full digits.
