2.1 Features
Chapter 2
RTD Input Channel
The RTD Input channel provides a DC excitation current to and accepts millivolt
signals from a standard platinum, 100Ω Resistance 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. Recalibration 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 selectable 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.

2.3.2 4-Wire RTD Connection
Do not connect anything to the pins labeled as “N/C”. Damage to the instru-
ment or loss of accuracy may result.
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.

page 10 008-0608-01
Page 11
2.3.3 3-Wire RTD Connection
2.3.4 2-Wire RTD Connection
If the cost of 4-wire cable is an issue, it is possible to use a 3-wire RTD connection 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
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.

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.
See “Wiring” on page 10.
Step 2: Enter the

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 applications. If desired, accuracy may be improved by calibrating over a narrower temperature 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.

Sub-Menu
This sub-menu contains four items that control the Digital-to-Analog Converter
(DAC) output of the channel.
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 instrument, the output of this Virtual channel could be used to drive this channel’s DAC
output.
If the DAC is set-up to be driven by its own channel’s tracking value, the Analog
Output will have the frequency response specified by “Channel Specifications” on
page 13. Otherwise, the Analog Output will operate more slowly.
Menu Item This designates the data source of the channel monitored by the analog output.
Each channel has three data sources: the live tracking value (TRACK), its highest
value (PEAK), and its lowest value (VALLEY).
The options for this menu item are:
•“
•“
” means the live tracking value of the channel.
TTTTRRRRAAAACCCCKKKK

“Zero output” might be 0 Volts, 2.5 Volts, 5 Volts, 4 mA or 12 mA depending on if
the channel has a voltage or current output and how it is configured. See the
“Digital-to-Analog Output” section of this chapter for details.
Menu Item Specifies what value, in engineering units, corresponds to full output on the Ana-
log Output.
“Full output” might be 5 Volts, 10 Volts or 20 mA depending on if the channel has
a voltage or current output and how it is configured. See the “Digital-to-Analog

3.1 Features
Chapter 3
Frequency Input Channel
The Frequency Input channel accepts square wave or sine wave input signals
from such transducers as magnetic pickups, devices with TTL outputs, or devices
with PNP or NPN transistor outputs. These signals are AC coupled into a zerocrossing detector, digitized, converted into engineering units, and placed into the
track, peak and valley data values of the channel. A 5V excitation is available in
case it is required by the device.
Setup and calibration of the channel is made at the factory. Re-calibration can be
made manually through the SETUP mode with the known-load calibration method
and a customer-supplied frequency calibrator.
The engineering units used to display the frequency are Hz. A Mathematics Virtual channel can be factory programmed for specific applications that required
conversion into units of RPM or horsepower.
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.
3.2 Getting Started Quickly
As shipped from the factory, the Frequency Input channel is calibrated and ready
for use.
Connect the output of your transdcuer to the Frequency Input channel according
to “Wiring” on pag e34.

3.4 Calibration
A listing of all menu items for this channel is given in “Setup Menu Reference” on
page 55.
A customer-supplied signal generator is required for re-calibration. It should be set up
to produce a square wave output at 1V peak-to-peak amplitude.
Step 1: Wire the signal generator to the channel’s connector.
See “Wiring” on page 34.
Step 2: Enter the

Sub-Menu
This sub-menu contains four items that control the Digital-to-Analog Converter
(DAC) output of the channel.
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 instrument, the output of this Virtual channel could be used to drive this channel’s DAC
output.
If the DAC is set-up to be driven by its own channel’s tracking value, the Analog
Output will have the frequency response specified by “Channel Specifications” on
page 37. Otherwise, the Analog Output will operate more slowly.
Menu Item This designates the data source of the channel monitored by the analog output.
Each channel has three data sources: the live tracking value (TRACK), its highest
value (PEAK), and its lowest value (VALLEY).
The options for this menu item are:
•“
