Introduction
Thank you for purchasing your REED R2800 Temperature Simulator. Please
read the following instructions carefully before using your instrument. By
following the steps outlined in this manual your meter will provide years of
reliable service.
Product Quality
This product has been manufactured to meet the stated product specications.
If a certicate of calibration is required please contact the nearest authorized
REED distributor or authorized Service Center. Please note an additional fee for
this service will apply.
Safety
Never attempt to repair or modify your instrument. Dismantling your
product, other than for the purpose of replacing batteries, may cause
damage that will not be covered under the manufacturer's warranty.
Servicing should only be provided by an authorized service center. To
avoid injury to the user or damage to the instrument, please read the
safety information below before initial use:
• Donotoperatetheinstrumentaroundammableorexplosivegas,
vapor or dust.
• Neverapplymorethan30Vbetweenanytwoterminals,orbetweenany
terminal and ground terminal.
Note: For optimal accuracy, allow the instrument to warm up 5 minutes
before operating. If the automatic reference-junction temperature
compensation of the instrument deviates from its designed accuracy,
contact an Authorized REED Service Center.

Operating Instructions
Power ON/OFF
Press the POWER button to turn the instrument on. Press and hold the
POWER button to turn the instrument off. When the instrument is on, it
will begin an internal self-diagnosis at which time the full screen will be
displayed. When complete, the instrument is ready to take measurements.

As a default the instrument will automatically turn off after 15 minutes of
inactivity. To turn off this feature:
1. Turn the meter off.
2. Press the POWER button (to display the full screen).
3. Quickly press the RANG button when the instrument is in the

Output Function
• TheoutputterminaloftheinstrumentcanproduceDCvoltagessetby
the user or can simulate resistance.
Do not apply any voltage to the output terminal during the operation.
If any improper voltage is applied to the output terminal, it will cause
damage to the internal circuit.
Simulating Output from DC Voltage
1. Insert one end of the test lead into
theoutput(TC/mV)jackofthe
meter and connect the other end
to the input of the instrument under
test, as shown in the diagram to
the right.
2. Press the FUNC button to select
"DCVoltageOutput"."V"will
appear on the display.

8. Press the °C/°Fbuttontoselecttheunit°Cor°F.
Note: During the direct calibration of an instrument with reference-junction
temperature compensation, it is recommended to press the RJ-ON button
so that the instrument can start the function of automatic reference-
junction compensation. Thus providing the required thermo-electromotive
forceforoutputfollowedbydisplayingthesymbol"RJ-ON"where:
Output thermoelectric force = corresponding emf of set
temperature – emf of room temperature
•
It takes two seconds for the instrument to start its internal referencejunction
temperature. After this, each automatic compensation occurs at
10 second intervals.
