Functional Diagram for the 41-760-001 Millivolt Thermocouple Simulator Module
The 41-760 is a low voltage source module ideal for
simulating the operation of a thermocouple, available with
a choice of 32, 24, 16 or 8 channels. Each channel of the
41-760 provides a low voltage output across two connector
pins capable of providing ±20 mV with 0.7 µV resolution,
±50 mV with 1.7 µV resolution and ±100 mV with 3.3 µV
resolution, covering most thermocouple types.
The use of two wire outputs ensures that the 41-760 can
be used to accurately simulate low voltages even in the
presence of common mode voltages in the system. Each
Vcold connection is independent permitting the 41-760 to
be connected to multiple cold junctions.
Each simulation channel is able to provide an open circuit
setting to simulate faulty wiring connections to a sensor.
For improved accuracy each channel of the Low Voltage
Source carries accurate calibration data stored in EEPROM
on the module. Regular calibration of the channels is not
necessary.
When used for Thermocouple Simulation the 41-760 can
be connected straight into the measurement system,
bypassing the need for Isothermal Blocks and Cold
Junction Compensation. To aid in this, Pickering offers a
78-pin connector solution that has 32, 24, 16 or 8 copper
twisted pairs terminated with mini copper thermocouple
plugs. Use of copper connections minimizes offset voltage
generation in the connection interface.
Alternatively Pickering can also supply connector blocks
that convert the copper connections of the module’s 78-pin
connector to that of the required thermocouple type.

MILLIVOLT THERMOCOUPLE SIMULATOR MODULE 41-760
GUIDANCE ON USING THE MODULE
The 41-760 behaves as a precise but adjustable low voltage source, making it ideal for Thermocouple Simulation.
As well as Thermocouple Simulation, it can be used for applications that require a reference voltage with ne
adjustment, with high accuracy and stability.
The module responds directly to a request for a particular voltage and is therefore very easy to use in a system.
Applications programs are easily generated to convert, for example, temperature requests to voltages for different
types of Thermocouple that are to be emulated.
Each channel is independent and has an “input” connection, Vcold, and an “output” connection, Vo. The Vo
connections provide an output voltage relative to Vcold, allowing the channel to compensate for the presence of
small voltages on the Vcold connection.

78-Pin D-Type Front Panel Connector
Figure 2.6 - Each channel is independent and has separate “input” and “output” connections
Note: While each channel is independent from the others, Vcold ratings relative to module front panel ground must
be observed. If the Vcold voltage is signicantly different to module front panel ground then users should be aware
of the common mode rejection ratio provided by Vcold.
Voltage Range
The 41-760 provides three output voltage ranges. The available ranges are +/-100mV, +/-50mV and +/-20mV. The
20mV range has the nest output voltage resolution and the 100mV range the coarsest output voltage resolution.
There are four voltage range modes dened in the driver. These are High (+/-100mV), Medium (+/-50mV or Low
(+/-20mV) ranges. The fourth mode is an auto-range, the default setting, which automatically switches between the
three ranges according to the requested voltage in order to provide the nest voltage resolution and best accuracy
available. At the changeover point between each range there may be small discontinuities in the output voltage
steps.
Remote Sense
At start up the 41-760 defaults to where the channels all connect their Vcold to the modules front panel ground as
a reference. This conguration only requires a single connection to the module using the Vo line for each channel.
For normal operation, remote switch should be closed.
The module also features a mode where Vcold remotely senses the “ground”. If for example the remote “ground” is
100uV different to the module front panel ground then the voltage on Vo will be automatically corrected to remove
the 100µV error that would otherwise be present at the remote point.
If the Vcold line is left unconnected but remote sensing is still enabled, the module will default to using the module’s
front panel ground for Vcold.

Isolation Switches
The 41-760 isolation switches on each channel provide the ability to disconnect the channels from the UUT, providing
the benet of not requiring the removal of cabling when wanting to isolate the UUT.
Additionally, due to having independent control of the Vo and Vcold connections, the simulation of common cable
faults, for example a broken wire or connection, can also be simulated.

MILLIVOLT THERMOCOUPLE SIMULATOR MODULE 41-760
Thermocouple Simulation
The 41-760 connections to the front panel are copper based. Users should consider the consequences of using
thermocouple materials for connection to 41-760 channels.
Monitor Port
The monitor port, which is part of the main front panel connector, is a convenient way of measuring the output
voltage of a channel without having to use an external switching network to connect a DMM to each channel in turn.
The monitor port must only be used with a very high impedance load, such as a DMM, to avoid loading the voltage
channels.
The monitor port can be daisy chained with other modules (for example multiple 41-760 modules), as it has an open
condition.
Figure 2.5 - The Monitor Port Can be Daisy Chained Between Modules to Allow One DMM to Support
Multiple Modules for Monitoring Purpose
The monitor port has a multiplexer on the output, also known as the monitor multiplexer which multiplex all the active
channels to output port.
This feature is particularly useful when in-system monitoring is needed since one DMM can sequentially access all
the channels in a system without any additional switching.
Warning: The monitor port is purely use for monitoring purpose, exp. Indication on the operation status of the
module. It is not for the purpose of Verication or Calibration as the accuracy of output on this port cannot be
guaranteed due to the tolerance in the multiplexer.

SECTION 3 - INSTALLATION
SOFTWARE INSTALLATION
First install the appropriate Pickering PXI switch card drivers by running the installer program Setup.exe (provided
in a compressed zip le), either from the CD-ROM supplied, or by downloading the latest version from our website
pickeringtest.com - the recommended method. Setup is accompanied by a ReadMe le containing
additional installation information. A single installation covers all cards in the System 40, System 45 and System
50 ranges.
When installation completes, the installed drivers’ ReadMe le is offered for display. It can also be displayed
later using a shortcut on the Programs>>Pickering menu.
If you are not a LabVIEW user you should choose the “full” version, and once that has been installed run
the LabVIEW Runtime Engine installer via the shortcut on the Programs>>Pickering menu. In the absence of
LabVIEW the Runtime Engine is required to support the Pickering Test Panels application.

HARDWARE INSTALLATION
ELECTRICAL CONNECTION (CHASSIS)
1. The chassis must be electrically installed in accordance with local regional electrical codes by a qualied
engineer.
2. The chassis must be grounded.
Electrostatic discharge can damage the components on the module. To avoid such damage in handling the
board refer to page VII.
Ensure that there is adequate ventilation.
The module should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. Choose an appropriate slot in the rack.
3. Remove the blanking plate for the chosen slot.
4. Ensure that the injector/ejector handle is in its downward position. Align the module with the card guides on
the top and bottom of the slot.
Do not raise the injector/ejector handle whilst inserting the module as the module will not insert properly.
5. Hold the handle whilst slowly sliding the module into the card guides until the handle catches on the injector/
ejector rail (refer to Figure 3.1).
6. Raise the injector/ejector handle until the module rmly seats into the backplane. The front panel of the
module should be ush with the front panel of the chassis.
7. Secure the front panel of the module using both screws to the chassis front panel mounting rails.
8. In a system employing a remote control interface to connect an external controller to a PXI chassis or to link
multiple chassis, power-up the system as follows:
a. For a system comprising an external controller and one chassis, power up the chassis before powering up
the external controller.
b. For a system comprising more than one chassis, turn ON the last chassis in the system followed by the
penultimate, etc, and nally turn ON the external controller or chassis containing the system controller.
9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up
sequence.
