Detector (RTD)
The calibrator accepts Pt100, Pt1000, Cu50 and Cu100, etc. The calibrator
accepts RTD measurements inputs in two-, three-, or four-wire connections,
with the three-wire connection the most common. A four-wire configuration
provides the highest measurement precision, and two-wire provides the lowest
measurement precision.
To measure temperature using an RTD input, proceed as follows:

5.2 Application of Resistance
Temperature Detector (RTD)
Connect the calibrator and the instrument to be tested according to the Figure
5.2-1. Simulation of RTD should be based on the following steps:
Three-wire (3 W) and four-wire (4 W) terminals are just for measurement, not
output simulation. The calibrator can simulate a two-wire RTD output in the front
panel. To be connected to a three-wire or four-wire transducer, use folding
cable to provide extra wiring.

6 Advanced Application
6.1 Setting 0 % and 100 % output
parameters
As for stepping operation and percentage display, 0% and 100% should be set
before using. Some gear values have been set when delivered from the factory
and set values are illustrated below:
The default set values may not meet your requirements, so you can reset them.
Then you can display the percentage with stepping or ramp output as well as
display the percentage. Adjust the output value with keys , press and
hold or for a long time until the buzzer sends a “Ticking” sound to
define the new 0% or 100% values. The new defined span value is saved in the
calibrator storage automatically and remains effective after restart. The flowing
operations are available with the setting:

to 100%.
6.2 Auto Ramping the Output
Automatic ramping gives you the ability to continuously apply a varying stimulus
from the calibrator to a transmitter, while your hands remain free to test the
response of the transmitter.
When you press , the calibrator produces a continuously repeating 0 % -
100 % - 0 % ramp in your choice of three ramp waveforms:
each step.
Exit the slop output function, please press any key.
6.3 Factory Reset
Factory reset consists of the following items:
Start the calibrator and press until the buzzer works, and the recovery of
factory default will enter working mode when the recovery is completed.
Page 25
BRIGHTWIN BRT 2010 TEMPERATURE CALIBRATOR
Disposable batteries are used.
Electric quantity is enough.
7 Power
The calibrator needs 6 disposable LR03 model (size 7) alkaline batteries or 6
R03 model (size 7) nickel-metal hydride batteries (or nickel-cadmium batteries).
The longest service life of alkaline batteries can reach 50 hours.
A 12V/1A power adaptor is used for charging and providing working power for
the calibrator.
7.1 Charge
When the battery indicator is pointed at , the remaining electric quantity is
less than 20%. Charge is necessary for normal operation of the calibrator. The
LCD backlight will start operation and the will display on the screen when
the power adaptor is used. If the battery indicator flashes, the calibrator
will be in the charging process, after which the battery indicator will stop
flashing.
The calibrator will stop charge automatically in case of the following
circumstances:
