Omega Products RD820-IA1 User Manual

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.

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
