The ChartScan/1400 is a compact voltage and temperature recorder that can beused as a paperless chart recorder or as adata logging and control instrument. The­convenient safety jack, subminiature plug,and screw-terminal connectors make signal
connection easier than other data recorders
or loggers. The system offers high-speed,
high-­channel counts, voltage isolation,and user-selectable signal c­ onditioning.
The ChartScan/1400 is a next-­generation
recorder that combines the ease-of-use
common in paper-based strip-chart recorders with the advanced features of PC-based
data acquisition systems. The ChartScan
offers distinct advantages over typical chart
recorders. For example, it is not prone tomechanical failure like conventional paperbased recorders with chart drives, paper
feeds, moving pens, and knobs.
Measurement Computing

ChartScan/1400 provides measurement and control

ChartView Software
The ChartScan/1400 includes ChartView,
one of IOtech’s Out-of-the-Box, Windows®based setup and acquisition applications.
ChartView provides a graphical spreadsheet-style user interface that lets you easily­configure your hardware, acquisition, anddisplay parameters. ChartView features ano programming ­approach that enables datacollection and display within minutes.

Isolated Inputs
The ChartScan/1400 is ideal for temperature and voltage measurements that requirechannel-to-channel isolation. The systems
provides 500V isolation for high-voltage
applications using the CSN14/HVX/S
module and 200V isolation when thethermocouple and other voltage modules
are used. The systems achieve this highisolation by using individual relays oneach ­channel, yet still maintain a very
fast 147 ­channels/s scan rate.

Faster Scanning
The ChartScan/1400 offers faster scanning
than a typical strip-chart recorder, andexceeds the typical two Hz rate found on
most strip-chart, multi-point, or hybrid
recorders. The unit provides an arrayof scanning capabilities to meet your(508) 946-5100

The ChartScan/1400 portable recorder is ideal
for making isolated temperature and voltage
measurements (notebook PC not included)
application requirements. Because datalogging and chart recording applications
frequently require logging at fixed timeintervals, the system uses the standard
hours-­m inutes-seconds (hh:mm:ss.s)
format to specify the time interval between­channel scans. Users can configure the unit
to begin and end data logging on a specified

General Information
event such as a TTL signal, temperature level, alarm condition,
absolute time of day, or upon completion of a specified numberof readings.

Noise Filtering. The system reduces noise by sampling and averaging 32 measurements per line cycle. The system also offers theflexibility to average across multiples of 1, 2, 4, or 8 line cycles.

Programmable Scan Rates. The ChartScan/1400 offers programmable scan rates for applications requiring acceleration of themeasurement rate on a specified event, such as an alarm condition.
For example, you can program the instrument to scan once per minute and then, upon the occurrence of a specified alarm condition,
switch to scanning once per second. Upon cessation of the alarm
condition, the unit resumes scanning at the rate of once per minute.

High-Accuracy Cold Junction Compensation. The CSN14/TC/P
thermocouple/volt scanning module features multiple, strategically located temperature sensors that provides high-accuracy,
cold junction compensation across all inputs.
Accurate Linearization. The system enables quick and accurate
linearization by providing built-in lookup tables for popular­thermocouple types, including J, K, T, E, R, S, B, and N.

Scanning Techniques

AlarmsThe ChartScan/1400 offers three measuring modes for application flexibility. These include a line-cycle integration mode, ahigh-speed multichannel scanning mode, and a single-channel
burst mode. A discussion of the particular attributes of eachmeasuring mode follows.

Detecting an alarm condition is a common requirement in logging
applications and the ChartScan/1400 offers a number of modes
to facilitate alarm detection. With 32 digital TTL alarm outputs
available on the 50-pin rear panel connector multiple ­conditions
can be set and monitored. ­Unlike some instruments which allow only one channel to be assigned to a single alarm output,
the ChartScan/1400 ­allows one or more channels to be logically“OR-ed” and connected to an alarm output. In this way, all 64
channels can participate in the alarm process. Channel settings
for alarm limit and hysteresis are individually set with the alarm
output remaining high for as long as the alarm condition is valid.

Line-Cycle Integration. The ability to sample and average 32
measurements per line cycle over multiple line cycles, makes
the systems useful for high-accuracy applications and thermocouple measurements in applications subject to high AC noise­environments. When engaged in line-cycle ­averaging, theunit provide AC or DC voltage, or linearized and compensated­thermocouple-based temperature readings at up to 44 channels/s.
The AC voltage measurement capability is ideal for power-line
monitoring applications. For each measurement, the unit calculates the equivalent true RMS voltage based on 32 samples it
acquires during each AC line cycle.

The units’ ability to automatically update alarm outputs in realtime affords you greater control of your applications and reduces
your programming burden by eliminating the need for constantper-channel m­ onitoring by the controlling computer.

High-Speed Multichannel Scanning. When line-cycle averaging is disabled, the system can average 1, 2, 4, 8, or 16 samples
per channel. When the unit is configured to take 1 sample perchannel, it can scan 147 channels/s or all 64 channels in undera half second. This is important when trying to time-correlatea large number of channels. By contrast, data loggers and othertemperature measuring instruments typically acquire readings
at only 5 to 20 channels/s.

In addition, the ChartScan/1400 can update alarmed output
channels in real time, at their programmed scan rates, and canalert the host computer of active alarm conditions.

Real-Time Clock
The ChartScan/1400 features a real-time clock that allows you
to synchronize acquisition to a specific time of day. Duringacquisition, the system stores the time and date of every data
scan in memory, enabling later retrieval of this information foruse in plotting and analyzing measurements. The instrument also
time and date stamps each channel’s high and low excursions,providing a precise time record of a channel’s minimum andmaximum values.

Single-Channel Burst Mode. In single-channel burst mode, thesystem can sample at up to 20 kHz on a single channel and store
the data in memory. When performing post-acquisition waveform
analysis such as Fast Fourier Transforms (FFTs), the unit can returneach data point in a waveform to your program. Alternatively,
the unit can provide a true RMS value of the sampled voltage.

MemoryAccuracy

For high-speed and long-term data ­logging, the systems areequipped with 128 Kreadings of data storage. Since eachapplication requires different measurements, each channel’shigh, low, and last readings are available throughout ­acquisition.
A 4 Mreading memory option is also available.

The ChartScan/1400 has a number of features and capabilities
that enable it to deliver the high accuracy demanded by many
research applications.
High Resolution. The system is equipped with a high-speed
16-bit A/D converter. This enables the system to offer up to 0.1 ˚Cand 3.05 µV resolution with the CSN14/TC/P ­thermocouple/volt
scanning module.

Scanning Modules
Temperature & Voltage Modules
All scanning modules feature isolated, differential input capabilities that can make accurate measurements in high common-mode
voltage applications. Each relay-isolated channel can be scanned
at up to 147 channels/s. In that time, all channels are logged tomemory, high/low/last registers are updated, alarms are reported,and thermocouple inputs are cold junction compensated andlinearized. Modules can be mixed to match your application.

Input modules are ideal for making isolated temperature andvoltage measurements. Each features 16 isolated inputs and plugs
directly into the ChartScan/1400.
Depending upon the module and signal input, cards have either
safety jack, or thermocouple plugs for quick and easy input
connections. The modules slide into a shielded metal ­enclosure
within the ChartScan/1400, keeping noise to a minimum andmaintaining a stable internal temperature for accurate Cold
Junction Compensation (CJC) reading.
