Chapter 1 General Description
1.1 Recorder Description
The Solid State Data Recorder is a Paperless Recording instrument. Data is stored on either an internal floppy
disk, a removable PCMCIA memory card or a Zip Drive.
All data is stored in MSDOS format and may be archived or analyzed on any IBM compatible PC running Microsoft
Windows 3.1 or Windows 95/98 using the available Companion Software. The instrument retains all the features of
a traditional Paper Chart Recorder by virtue of its large STN monochrome or TFT color Liquid Crystal Display (LCD)
which presents the data in the traditional chart mode as well as in bar graph or digital numeric form.
The unit has many features and functions which are unique and cannot be performed on traditional paper recorders,
such as data compression and historic data browsing. The recorder is programmed via a touch screen keypad on
the display.
The recorder will measure and process up to six direct inputs, calculated, conditional, or external points for logging,
trending, or data manipulation.
If direct inputs are not desired, the Data Recorder will accept up to fifteen points from a combination of calculated,
conditional, or external point types.
1.1.1 Inputs
Direct input sources may come from voltage, current, dry contacts, thermocouple, or RTD sources. The
voltage and current ranges accepted by the instrument include: ±150 mV, ±1.25 V, ±2.5 V, ±12.5 V, and ±25 V;
4 to 20 mA, 0 to 20 mA and 10 to 50 mA current. Thermocouple inputs include Type J,K,T,E,R,S,B,C and N.
RTD inputs accepted include 10 ohm Cu, 100 ohm Platinum, 200 ohm Platinum, 120 ohm Nickel and 1000
ohm Nickel.
1.1.2 Instrument Size
The instrument is sized to fit in a DIN standard panel cutout of 5.43 inches x 5.43 inches [138 mm x 138 mm]
and requires 7.41 inches [188.2 mm] behind panel depth, not including power and input source cable space
needed. Actual dimensions of the instrument are shown in Figure 2-1 Recorder Dimensions in Chapter 2 of this
manual.
1.1.3 Menus

bottom right hand corner of the LCD screen. The STATUS bar along the top of the screen displays the various
recorder parameters. (Refer to Section 3.1). The Command Button Bar contains three user programming option
