Safety
This recorder is compliant with the requirements of EN61010-1, UL 61010C-1 & CSA C22.2
No. 1010.1-92. The protection provided by the recorder may be impaired if it is used in a
manner inconsistent with its intended purpose, or in an environment that exceeds the
specifications of the recorder. Omega Engineering, Inc. is not liable for customer’s failure to
comply with these requirements.
Safety Symbols
The following symbols may be seen on the recorder labeling.
Protective Earth
DC Supply
Safety Notes and Precautions
1. The protective earth terminal should be connected first before any other connection is made.
To avoid making the recorder dangerous under fault conditions, any interruption of the
protective Earth conductor inside or outside the recorder is prohibited. Even in the case of a
portable unit, the protective earth terminal must remain connected if the recorder is
connected to any hazardous voltage.
2. Keep signal and supply voltage wiring separated from one another. If this is impractical, use
shielded cables for signal wiring. Double insulation should be used for signal wiring when
the recorder is being used with hazardous voltage.
3. Do not use the recorder where there is high vibration, or high magnetic field, this could cause
damage or error of measurement.
4. All maintenance or repairs should be carried out with power disconnected, to avoid personal
injury, or damage to the unit.
5. In areas with conductive pollution, adequate ventilation, filtering and sealing need to be
installed.
4
6. When cleaning the recorder, handle carefully and use soft dry cloth. Avoid the use of
abrasives or any sharp and hard objects which would damage the display.
7. Do not operate the recorder if any part has been removed or disassembled. Consult your
nearest dealer at once.
Static Electricity
Appropriate precautions must be taken when handling the recorder. The circuit board,
components are susceptible to damage caused by electrostatic discharge. Take static electricity
precautions whilst handling and inserting Compact Flash Card into the recorder.
To replace the power-line fuse
The power-line fuse is located within the fuse-holder on the power board. For 90-250 VAD
line voltages, the user must use a 2.5A time-lag fuse, and for both 11-18 VDC and 18-36 VDC
line voltages, a 5.0A time-lag fuse must be used.

1. General Description
1.1 Unique features of recorder
The RD8900 is a well-designed paperless recorder with many outstanding features including:
• 6.1〞TFT Color LCD with VGA Display in 640x480 pixels.
• 18 isolated Analog Inputs
• Plug & play I/O cards for easy expansion
• Simple and friendly operation
• Infrared detector to prolong lifetime of LCD
• Solid storage media CF card in high capacity
• 174 mm short depth
• Ethernet as standard and optional RS-232/422/485 communication
• High accuracy 18-bit A-D Analog Input
• 15-bit D-A Analog Output.
• 200 milli second sample rate.
• Bench top with convenient portable handle, easy converted into panel mount
1.2 Expandable Input and Output Cards
The recorder is equipped with six-rear expansion slots, which work flexibly with the following
plug & play I/O cards.
Analog Input cards (part number AI181, AI182, AI183 ) : These three cards are used for 1, 2,
& 3-channel analog input. Each input is isolated from each other to avoid noise and to ensure
stable measurement. Analog input is configured by DIP switches and jumpers on the card
before plugging into rear expansion slot. Refer 2.3 Setting Input and Output Cards.
Digital Output card ( DO181 ): Each card includes 6 alarm relays. Contacts are rated 5
Amp/240 VAC
Digital Input card ( DI181 ): Each card includes 6 channels. Logic Low: -5V minimum, 0.8V
maximum, Logic High: -2V minimum, 5V maximum
1.3 Communication
The standard communication interface is Ethernet with protocol IEEE 802.3 - 10 Base T. Other
options are RS-232 / RS-422 / RS-485.

1.4 Storage Media CF Card
The Solid Compact Flash Memory Card (CF Card ) 16 MB capacity is a free standard storage
media used for this instrument. Its compact size, anti-dust and anti-vibration features increase
its reliability. To read measured data on CF Card, add a CF reader on USB port of PC. Higher
capacity 64 and 128MB CF Cards are upon request. Alternatively the user may purchase locally.
To ensure compatibility, we recommended only two brands SanDisk and Transcend.
To read the configuration and measured data on CF card for the first time, it is necessary to
press Save key to save configuration, and then press Dump key to Dump measured data from
the recorder to the CF card before inserting it into the CF card reader. If configurations been
changed afterwards, press both keys before insert CF card into reader. If configuration remains
unchanged, press Dump key only.
Each record of data uses 2 bytes of CF card memory.. If the Log Speed ( the recording speed of
measured data ) is set to the fastest speed at 1 second per data, then for a single channel, 16
MB CF card will last approximately 92 days [= 16 MB / ( 2 bytes x 24 hours x 60 minutes x
60 seconds ].
The following formula is to calculate how many days the CF card could do saving before it is
full.
The ? days = The capacity of CF Card / ( 2 bytes / the Log Speed x the working hours per
day x 3600 seconds )
To avoid loosing recorded data while storing on PC, it is necessary to insert CF card back
again into the recorder soon after loading recorded data onto PC.
1.5 Data Security
The recorded data is stored in the manufacturer’s special binary format. It is not possible to
manipulate or modify those recorded data. This feature fully guarantees the security of the
data.
1.6 Infrared Detector ( IR Detector )
The use of Passive Infrared technology on the recorder is an innovative idea to prolong the
lifetime of the LCD display. The detector senses the movement of body heat from a distance of
approximately 2 meters. This feature works together with the Screensaver. For example, if the
IR Sensor is turned on and Screensaver set to 10 Min, then the display will turn off 10 minutes
after the user walks away from the recorder. The Passive Infra Red detects when the user
returns to the recorder and the display turns on straight away, no need to press any key on the
recorder. If the user does not prefer using this function, it can be disabled.

2. Installation and wiring
2.1 Unpacking
If any damage is found while unpacking, the user should contact the local representative at once.
It is suggested that the special packaging is retained for possible future requirement.
2.2 Installation
Remove stains from this equipment using a soft, dry cloth. Don’t use harsh
chemicals, volatile solvent such as thinner or strong detergents to clean the equipment in
order to avoid deformation or decoloration.
The recorder is designed for indoor use and not in any hazardous area. It should be kept away
from shock, vibration, and electromagnetic fields such as variable frequency drives, motors and
transformers.
It is intended to be operated in the following environment:
Pollution Degree Level II IEC1010-1( EN61010-1 )
Temperature 5 ~ 50 ˚C
Humidity 20 ~ 80 % RH ( non-condensing )
Power 90 ~ 250 VAC, 50/60 Hz

Holding the handle so that the instruction side is visible, pull the handle outward by both hands
and put it in vertical position on the top of case. Then, slide the handle into both ears as Figure
2-9. Rotate the handle downward as Figure 2-10 & 2-11. Lastly, slide both feet beneath the
case and straighten up the stoppers as Figure 2-12 ∼ Figure 2-14. The bench top recorder is
now mechanically ready.
