Voltage Inputs, available in blocks of sixteen (16), are
easily assigned to test channels. These voltage inputs are
high impedance, fully isolated, and are offered in various
ranges such as: ±5 volts, 0 – 10 volts, etc.
Any combination and quantity of voltage inputs may be assigned
to a test channel. Data measured by these inputs becomes
part of the data record for the test channel assigned and
voltages measured can control flow of the test procedure
(schedule).
Reference voltage inputs may be used for: 3 or 4 reference
electrode experiments; measuring individual cells within
a pack, monitoring external voltages, etc. Readings may
be viewed or plotted in real time, or plotted either as
a single input or overlay all the inputs associated with
the experiment.

Thermocouple Inputs, available in panels with sixteen (16)
inputs, are software assignable in any combination or quantity
to a test channel. Thermocouple Input panels are offered
for Type "K", "T", and "J"
thermocouples. Each panel must be for one thermocouple type.
Data measured by these inputs becomes part of the data record
for the test channel assigned creating a historical record
of temperature for the test schedule. Temperature functions
can be used to control flow of the test schedule on channels
with thermocouple inputs on the basis of absolute temperature,
T/dt, T, and several others.
-
Thermistor Inputs, available in panels with sixteen (16)
inputs, are software assignable in any combination or quantity
to a test channel.
Data measured by these inputs becomes part of the data record
for the test channel assigned creating a historical record
of temperature for the test schedule. Temperature functions
can be used to control flow of the test schedule on channels
with Thermistor inputs on the basis of absolute temperature,
T/dt, T, and several others.
Pressure Inputs, available in panels with sixteen (16) inputs,
are software assignable in any combination or quantity to
a test channel.
Data measured by these inputs becomes part of the data record
for the test channel assigned creating a historical record
of pressure for the test schedule. Pressure functions can
be used to control flow of the test schedule on channels
with pressure inputs on the basis of absolute pressure,
P/dt, P, and several others.

External Charge Controllers can be added to any or all of
the test channels. These devices work as follows: The test
channel retains all of the capabilities it normally has.
In addition, tests run on the channel can connect to an
external charger during a charge controller step. During
such connection, all the data gathering capabilities and
all the step end conditions of the test channel can still
be used.
External Load Controllers can be added to any or all of
the test channels. These devices work as follows: The test
channel retains all of the capabilities it normally has.
In addition, tests run on the channel can connect to an
external load during a load controller step. During such
connection, all the data gathering capabilities and all
the step end conditions of the test channel can still be
used.

Maccor's Frequency Response Analyzer (EDA 0305) may be added
to new and existing test systems running Maccor's Windows
based software. The EDA and eight (8) position Multiplexer
add full AC impedance analysis to a test system allowing
frequency scans without disturbing the device under test
or its connections at any time during the test. The positions
on the multiplexer are assignable to any test channel in
the system.
Data from the EDA include: frequency, magnitude, phase angle,
real and imaginary impedances, and capacitance or inductance.
Standard plots available in the MIMS Client include: Nyquist,
Bode, magnitude, real, imaginary impedances, and phase angle
versus frequency, real or imaginary impedances, cycle, voltage,
capacity, energy, or power.
New test system's interface can be fitted with a LED status
indicator. The LED provides a visual indicator on the test
system when the channel is active.
The SMBus battery interface, offered in modules of twelve
positions, is used to read and write to certain registers
of SMBus compliant battery packs. The fields read by the
test channel are added to the channel's data file. The test
channel responds to different SMB alarms during testing.
If a test step ends on an alarm, the data file will have
the appropriate end code.
The data from the Smart Battery pack consists of header
and data information. The data read from the SMBus Battery
pack can be viewed in real time for the test channel the
pack is assigned.
This hardware option provides eight TTL optically isolated
input bits for a tester channel. The flow of the test procedure
may be controlled based on the bit values (high or low).
-
With this hardware option, a tester channel may set individual
lines of TTL outputs high or low during the test. These
lines may be used to trigger an event or simply display
status lights.
-
This option allows test channels to peform popular Telecom
and similar pulse profiles. The period for the tester channel
is adjustable from 4 to 10 mS, with pulses available from
100 µS on up. All channels on a single controller
board are set to the desired period. In the test procedure,
the magnitude and pulse duration are set.
For demanding tests, this options provides the flexibility
to create a train of up to sixteen sub-millisecond pulses.
Individual pulses may each be less than 100 µS provided
one of the pulses is greater than 1 mS. Once the train has
been created, it is looped until the programmed end criteria
is reached.
-
Test systems are designed to detect power outages and avoid
losing any data when a UPS is used on the logic power supplies
and tester PC. System can be user configured to restart
suspended test when power is restored or wait for user intervention
depending on the length of the power outage.
