General Description
ChartScan is an easy to use, advanced hybrid data recorder that combines the desirable features of common
paper-based strip-chart recorders with the latest PC-based data acquisition technology. In addition to chart
displays, ChartScan allows you to display digital, analog, and bar graph meters.
paper-based strip-chart recorders with the latest PC-based data acquisition technology. In addition to chart
displays, ChartScan allows you to display digital, analog, and bar graph meters.
ChartScan requires no external signal conditioning or use of multiplexers. The unit can measure up to 64
differential input channels; and can easily be expanded up to 128 channels with the use of an expansion module.
differential input channels; and can easily be expanded up to 128 channels with the use of an expansion module.
ChartScan is well suited for temperature and voltage measurements requiring channel-to-channel isolation. This
isolation is made possible by the use of individual relays on each of the 64 channels. The unit provides 500 V
isolation for voltage inputs and 200 V isolation for thermocouples. The instrument scans at a rate of up to 147
channels per second and includes a single-channel burst mode for digitizing waveforms at rates up to 20 kHz.
Measurements include:

ChartScan includes ChartView, a software program which provides a Windows-based graphical-user-interface
approach to obtaining data collection and display; PostView, a post-acquisition data review program; and
ScanCal, a software application that automates instrument calibration.

Although ChartScan can acquire temperature readings at a rate of 147 channels/sec, you may also program the
unit to acquire data at specified time intervals using the
unit to acquire data at specified time intervals using the
hh:mm:ss.t
format. For the ultimate in flexibility, you
may also program separate pre-trigger and post-trigger sample rates. As an example, ChartScan can be
programmed to sample data once per hour and then sample once per second when channel 2 reaches 70°C.
An interface card can be plugged into ChartScan unit through a slot on the unit’s rear panel. When the only
interface desired is RS-232, no interface card is needed and the card interface port is shielded with a removable
protective cover.

Statistics such as High, Low, and Last are available for each channel for data reduction. In addition, up to
32 alarms may be programmed using the programmable high and low limits for each channel.
