RTD INPUT CHANNEL2
Chapter 2
RTD Input Channel
2.1 Features
The RTD Input channel provides a DC excitation current to and accepts millivolt
signals from a standard platinum, 100ΩResistance Temperature Detector (RTD).
These signals are digitized, converted into engineering units, and placed into the
track, peak and valley data values of the channel.
Setup and calibration of the channel is made at the factory for operation with a
customer-supplied Pt-100 RTD with a DIN-43760 standard calibration curve. Re-
calibration can be made manually through the SETUP mode with the known-load
calibration method and a customer-supplied RTD calibrator.
The engineering units used to display the temperature readings are field select-
able from a built-in conversion table. In addition, the engineering units used for
calibration can be independently selected.
Two rear panel control inputs can be field-configured for such functions as remote
track/hold, disabling peak/valley detection and clearing the peak/valley values. A
voltage or current digital-to-analog output is also provided.
2.2 Getting Started Quickly
As shipped from the factory, the RTD Input channel is calibrated for a standard
Pt100 (platinum, 100Ω@ 100ºC) RTD that conforms to the DIN-43760 / IEC751
standards (∝=0.00385). No further calibration is required prior to use.
Connect the RTD to the RTD Input channel according to “Wiring”on page 10.

page 10 008-0608-01
2.3 Wiring
2.3.1 Channel
Connector
The pin-out for the channel’s connector is shown in the following table.
The Analog Output and Analog Return pins are electrically isolated from all other pins
on the instrument.
Do not connect anything to the pins labeled as “N/C”. Damage to the instru-
ment or loss of accuracy may result.
2.3.2 4-Wire RTD
Connection
Use a 4-wire RTD connection when the highest possible accuracy is desired. The
excitation current from the instrument will be carried by two wires and the voltage drop
across the RTD will be sensed with the other two wires. Since the (+)Signal and (-
)Signal pins are high impedance inputs, there is little current flow through these wires
therefore the resistance of the wires doesn’t add to the resistance of the RTD.

RTD INPUT CHANNEL2
2.3.3 3-Wire RTD
Connection
If the cost of 4-wire cable is an issue, it is possible to use a 3-wire RTD connec-
tion that shares many of the benefits of the 4-wire connection. The wire lengths
should be equal and the wire type should be identical. This will equalize wire
resistance and thus obtain the best accuracy.
Figure 2-2: “3-Wire RTD”Connection to RTD Input Channel
2.3.4 2-Wire RTD
Connection
The 2-wire connection scheme is not recommended unless the cable length is
short. The wire’s resistance will add to the resistance of the RTD and result in
reduced accuracy.

page 12 008-0608-01
2.4 Calibration
A listing of all menu items for this channel is given in “Setup Menu Reference”on
page 55.
A customer-supplied RTD simulator/calibrator is required for re-calibration.
Although not recommended, field re-calibration of the channel for operation
with RTDs with outputs other than the Pt100 DIN-43760 / IEC751 standards
can be made; this may result in reduced accuracy and resolution.
Step 1: Wire the RTD simulator/calibrator to the channel’s connector.

”registers. This technique is used to compensate for the non-
linearity inherent in RTDs.
The calibration points used for factory calibration are -200ºC, -100ºC, +0ºC, +100ºC
and +200ºC. Using these temperatures for calibration is recommended for most appli-
cations. If desired, accuracy may be improved by calibrating over a narrower temper-
ature range which decreases the difference between the points.
Choosing calibration points where the difference between points is larger than
100ºC will result in greatly reduced accuracy.

The instrument expects the input signal applied at each known-load point
to be increasing. For example, the load applied at Known-Load Point 2/5
must cause the transducer to produce a more positive output than at
Known-Load Point 1/5.

Menu Item This chooses which channel will drive the DAC output. Normally, the DAC located
on a particular channel will be driven by that channel, but that need not be the
case. For example, if a Mathematics Virtual channel is installed on the instru-
ment, the output of this Virtual channel could be used to drive this channel’s DAC
output.
