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 specications.
If a certicate 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:
• Donotoperatetheinstrumentaroundammableorexplosivegas,
vapor or dust.
• Neverapplymorethan30Vbetweenanytwoterminals,orbetweenany
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.

8. Press the °C/°Fbuttontoselecttheunit°Cor°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
forceforoutputfollowedbydisplayingthesymbol"RJ-ON"where:

It takes two seconds for the instrument to start its internal referencejunction
temperature. After this, each automatic compensation occurs at
10 second intervals.

of the meter and connect
the other end to the input of
the instrument under test as
shown in the diagram to the
right. The dedicated test leads
supplied with the simulator are
intended for a 2-wire system
for testing output according to
user's requirement.
Note: An additional set of test leads are required for 3-wire or
4-wire systems.

Note: The instrument produces a simulation resistance up to 400Ω at
itsoutputterminal(RTD/Ω).Themethodofsimulatingresistanceoutput
istosendoutanappropriatevoltage'Vx'accordingtotheexcitation
current'Ix'producedbythecalibratedinstrument.BecauseR(set
resistance)=Vx(outputvoltage)/Ix(excitationcurrent),thecalibrated
devicemustprovideanexcitationcurrenttothesimulator.Theexcitation
current should range from 0.5mA to 2mA.
Note: When testing the resistance output of a 4-wire system while
employing a 2-wire connection, you should take into consideration the
error(approx.0.1Ω)arisingfromtheleadresistanceofthetestleads.If
the capacitance between the resistance output terminal of the simulator
and the tested instrument is more than 0.1μf, the simulator will produce
improper resistance.
Battery Replacement
When the battery symbol, , appears on the display, the battery needs to
be replaced. In order to replace the battery, proceed with the following steps.
1. Ensure that the meter is turned OFF
and remove any test leads from the
meter's terminals.
2. Liftthetiltstandonthebackoftheunit
to access the battery compartment
door which can be removed using a
Phillips head screwdriver.
3. Replacethe2xAAbatteriesinthelid
of the battery compartment.
4. Reinstall the compartment lid by ensuring that battery terminals
touch the unit's contact points and snap into place.
5. Tighten the screw to secure the battery compartment cover.
Note: Ensure battery door is closed and secured in place before using
the meter. To ensure proper operation, please wait 5 seconds before
turning meter on after changing batteries.
