The RD820 Series paperless recorder
provides single or dual channel realtime graphic display, recording, and
digital display in engineering units of
your measurements. The 160 x 80 pixel
LCD display offers exceptional clarity
with zoom, recall, scroll, rewind,
and replay capability. You can
compress data in time, scroll and zoom
data in amplitude and search for data
by alarm functions. You can view real
time, average, trend, or historical data.
The RD820 offers the ability to use data
cards, up to 1 MB in size, for storing
data, as well as recorder configurations.
Through an optional card reader or the
RS-232 port, data may be downloaded
to a PC for additional analysis, storage,
or hard copy printouts. The RD820,
with just five simple buttons on the
membrane keypad, is easy to use.
It provides versatile, reliable, low cost
display and storage of data in a rugged,
compact
1
⁄4DIN panel mount enclosure.

8 bits resolution
Time: Internal battery backed clock
tracks year, month, day, hours,
minutes, seconds.
Memory: Internal data buffer of 16 K
RAM, enables memory card to be
removed without loss of data. Data
storage direct to memory card.
Memory Card: PCMCIA 2.0
Compatible. Available in 256 K
to 1024 K bytes (equivalent to
1,000,000 readings @ 8 bits). Unit
automatically detects card size.
Multiple files per memory card. User
can select files from memory card
for replay.
Non-Volatile Memory: All settings
are stored in non-volatile memory.
Unit remembers setup even if all
power is removed.
Triggered Speed: Alarm setpoint can
be used to change sampling speed.
Two individual sample speeds can be
set, one for normal and one for alarm
condition.
For example, under normal conditions
record slowly, on alarm increase
recording speed for better definition of
problem period.
Triggered Record: Alarm setpoint
can be used to start and stop
recording. Monitor continually but only
record when threshold exceeded
Dual Cursor Mode:
Use to display delta time (time
differences) between events
RECORDING
Sample Rate: User selectable to
100 samples/sec. (10 msec)
Recording Method: User selectable–
Averaging, Peak, Valley, Normal.
Recording Time: up to 1,000,000 x
recording interval (at 8 bits)
Equivalent to 200+ hours at
1 sample/sec. (1 MB Memory Card)
DISPLAY
Display Type: Twisted Nematic LCD
Dot Matrix panel 160 x 80 pixels;
viewing area; 2.9 x 1.5" Backlighting
standard. Graph Direction: right to
left, Vertical Zoom Scroll
Viewing Modes: Normal, Zoom,
Compressed, SUM and Difference
Viewing Control: Real Time Data,
Historic Data, Rewind, Forward,
Search, Cursor Identification
Customization: User can customize
display by selecting line patterns, grid,
time/date stamp, and layout
INPUT
Input Display: 4 digit (-999 to 9999)
plus 3 characters for engineering units
(e.g., RPM, PSI)
