Introduction

The 6222 is a twelve-channel, 24-bit resolution thermocouple input module device that connects to a host PC‟s
Ethernet port (directly or via a network hub/switch) and can be synchronized with other 6000 series devices.

Up to twelve thermocouple inputs can be connected to each unit via front panel removable screw-terminal
connectors. Each of the channels has a TC+ and TC- connection.

As indicated by the block diagram in chapter 2, the 6222 contains three internal modules. Each supports four
thermocouple channels; and each module has a common terminal (COM) that is internally connected to an isolated
ground reference. Within a module channel to channel can be within 1.5V of each other and within 250V to ground
and within 250V to one of the other two modules.

The hardware provides the signal conditioning and acquisition engine, and the software defines the specific
configuration and analysis aspects of the system.

Front Panel

The front panel is populated with three removable screw-terminal connectors. Each of these connectors contains 10
terminals to support COM and three thermocouple channels. Each channel has two connection points, the odd
numbered terminals are the negative (-) input and the even numbered terminals are positive (+). Additional
information is included in chapters 3 and 8. Note that connector backshells can be fitted over the terminal­connectors to protect them and the associated thermocouple connections. Backshells are discussed further on
page 1-3.

After this, the Active light will signal communications with a host computer at a slower
blink rate.

Data

The Data light will be On any time the device is acquiring channel data that is available
to the host PC control software.

Note:

After turning on the device, it can take up to 2 minutes to reach ready state, depending on
network settings. This can be monitored by the LED sequence:
Power Light On Boot Light On then Off Active Light Off, then Blinking, then On.

Up to nine units can be synchronized. The total combined length of the SYNC cables is not
to exceed 2.438m (8 ft).

CABLE TIE MOUNTS: Two cable tie mounts are present to provide for strain relief of cables.

ETHERNET: The 10/100BaseT Ethernet port can connect to the Ethernet port of the host PC, or to an

Ethernet network. The Ethernet connector has two built in LEDs that indicate traffic flow on the network.
Refer to Accessories in the Specifications chapter for Ethernet cables available from Measurement

Connector Backshell (2 views)

Using a Ferrule

Connector Backshells and Ferrules

Connector backshells are optional protective casings that can be fitted onto the 6222 removable screw-terminal
connectors. The backshells provide a thermal shield to reduce the effect of short term ambient temperature changes,
and to ensure the accuracy of the cold junction measurement. They also provide mechanical relief and protection for
the TC wires and screw terminal connections.

Accuracy specifications are only valid when using provided connectors and properly installed backshells.

Terminating thermocouple wires with ferrules will also help maintain good connections in vibration applications,
but unless a backshell is used, there will be no protection to the screw-terminal connectors or to the wires at the
point of connection.

Each 6222 is shipped with three screw-terminal connectors and three backshells. Extra connector/backshell kits can
be ordered from the factory. Each kit contains one connector and one backshell.

6222 User’s Manual General Information 1-3

Up to nine units can be synchronized. The total combined length of the SYNC cables is not
to exceed 2.438m (8 ft).

Unplug sync cables from devices that are not intended to be part of a “Synchronized Device
Group.” Leaving a sync cable connected to an independent device can lead to errors.

Leaving an un-terminated sync cable on a synchronized device can lead to errors.

The sampled data phase relationship among channels between multiple devices is
dependent on the Channel Sync Skew specification for each device. When utilizing
different models in a multi-device system, any differences in the ADC filter delay
(“Input Delay”) should be added.

Reference Note: For detailed information refer to the Encore software‟s Comprehensive Help.

You can access the Help from within Encore. After doing so, navigate to the synchronization
related topic as follows from the Help‟s Contents panel:
Configuring Hardware>>Hardware Setup>>Synchronizing Devices.

Synchronization

To synchronize from two to nine 6000 Series devices, link
them together with synchronization cables as indicated in the
example figure. Note that the first device (relative to the
circuit) will be the Master. The last device connected will be
the Terminating Slave. Thus the synchronized devices must
proceed sequentially from the Master to Terminating Slave, as
indicated in the figures. Note that channel-to-channel phase
relationships in a multi-device configuration are not
necessarily fixed. See notes below.

After physically linking the devices via the sync cables, they must still be configured as a “Synchronized Device
Group” in the Encore software. To do this, use the Synchronize Devices page of Encore‟s Hardware Setup tab.

Each Synchronized Group consists of one Master Device
and at least one Slave Device. By default, the first 6000
Series device added to the Synchronization Group will be
the Master and the last device added to the group will be the
Terminating Slave.

Encore‟s Synchronized Device Group Configuration
panel includes a pull-down list which allows you to select
the device that you want to have function as Master and the
one you want to function as Terminating Slave, should this
be different than the default settings.

Encore will display a Synchronization Error icon if it
detects that a necessary synch cable is missing or not
properly connected.

Wiring

The 6222 has three 10-terminal, detachable screw-terminal connectors. Each of the three connectors supports
four thermocouple input channels. Each channel has a terminal to which you can connect the positive lead of
the thermocouple, TC+, and a terminal to which you can connect the negative lead of the thermocouple, TC–.

For each set of four channels (Channels 1 through 4, 5 through 8, and 9 through 12) the 6222 has a common
terminal (COM) that is internally connected to the isolated ground reference of the module. The following
figure shows the terminal assignments for each channel. Odd numbered terminals are negative (-) and even
numbered terminals are positive (+).

When connecting thermocouple input signals to the 6222, connect the positive lead of the thermocouple to the
TC+ terminal and the negative lead to the TC– terminal. If you are unsure which of the thermocouple leads is
positive and which is negative, check the thermocouple documentation or the thermocouple wire spool. If you
are using shielded wiring, connect one end of the shield to the COM terminal as indicated in the following
figure.

6222 User’s Manual Thermocouple Input 3-1

Circuitry

Analog Input Circuit for 1 Channel

The following figure represents a circuit for one channel. The two 10M ohm resistors produce input impedance
at the channel’s positive and negative terminals. The gain and offset errors that result from the source
impedance of the thermocouple will be negligible for most applications. Other voltage sources (with higher
source impedance) can introduce more significant error. Refer to the Specifications chapter for more
information about errors that result from source impedance.

Accuracy

This section pertains to various factors that have an effect on temperature measurement error. These are: the
type of thermocouple being used, the temperature being measured, the accuracy of the thermocouple, and the
cold-junction temperature.

Accuracy for Different Thermocouple Types

The following figures show the typical and maximum errors for the different thermocouple types when used
with the 6222 over the full temperature range. The figures also show the maximum error for the thermocouple
types with the 6222 at room temperature (15°C to 35°C). The figures account for gain errors, offset errors,
differential and integral nonlinearity, quantization errors, noise errors, and isothermal errors. The figures do not
account for the accuracy of the thermocouple itself.

Temperature gradients across the 6222 terminals affect the cold-junction temperature accuracy. Refer to the
upcoming Cold-Junction Temperature Measurement Accuracy sub-section for more information about
temperature gradients.

3-2 Thermocouple Input 897690 6222 User’s Manual

6222 User’s Manual Thermocouple Input 3-3

Cold-Junction Temperature Accuracy

Heat dissipated by the 6222’s internal circuitry and other nearby heat sources can heat up the unit’s terminals,
placing them at a different temperature than that of the cold-junction compensation sensor. The thermal
gradient generated across the terminals can cause terminals of different channels to be at different
temperatures; the resulting measurement creates errors not only in absolute accuracy but also in the relative
accuracy between channels.

The accuracy specifications (presented in Chapter 8) include the errors caused by the gradient across the
module terminals, and assume the use of properly installed connector backshells.

Minimizing Thermal Gradients

Thermocouple wire can be a significant source of thermal gradients if it conducts heat or cold directly to the
terminal junctions. To minimize these errors follow these guidelines:

Use small-gauge thermocouple wire. Smaller wire transfers less heat to or from the measuring

junction.

Run thermocouple wiring together near the screw-terminal connector to keep the wires at the same

temperature.

Avoid running thermocouple wires near hot or cold objects.
If you connect any extension wires to thermocouple wires, use wires made of the same conductive

material.

Install connector backshells.

equipment. Most laboratory and industrial environments suffer from multiple sources of electrical noise.
For example, AC power lines, heavy equipment (particularly if turned on and off frequently), local radio
stations, and electronic equipment can create noise in a multitude of frequency ranges.

Local radio stations are a source of high frequency noise, while computers and other electronic equipment
can create noise in all frequency ranges. Creating a completely noise-free environment for test and
measurement is seldom practical. Fortunately, simple techniques such as using shielded/twisted pair wires,
filtering, and differential voltage measurement are available for controlling the noise in our measurements.
Some techniques prevent noise from entering the system; other techniques remove noise from the signal.

While many techniques for controlling noise in signals provide a means of removing the noise that is
already present, the preferred solution is to prevent the occurrence of noise in the signal in the first place.

The following practices, some of which are required for CE compliance, should be employed to minimize
noise.

Make a solid earth ground connection. Using insulated, low resistance wire, connect the

chassis to solid earth ground. This practice accomplishes the following:
(a) keeps radiated emissions low by keeping the chassis electrically quiet,
(b) keeps potential common-mode voltages low,
(c) improves user safety, and
(d) provides a safe path for Electrostatic Discharge energy back to earth ground.

Minimize ambient EMI. The lower the ambient EMI, the better. Sources of electromagnetic

interference include solenoids, motors, computer equipment, high power distribution wiring,
etc.

Distance cables. Route signal cables away from Ethernet lines, Mains and other high voltage

cables and equipment to minimize signal interference from radiated noise.

Encore is the premier Out-of-the-Box data acquisition software package and is included with each 6000 Series
module. Encore combines ease of use with advanced functionality, including customizable data layouts, powerful
analysis, and reporting capabilities. Instead of having a program to log data, another to analyze, and a third to
develop report data, Encore includes the functionality of all three into one package, thus shortening the learning
curve, and saving time and cost.

Features

Easily configure 6000 Series hardware
Data streaming & playback
Comprehensive report generation
Drag and drop directly into Excel
Built-in analysis including FFT

We recommend that you watch the Encore Quick Start Video Tutorial prior to using Encore. After watching the
video you should be able to set up and run an application. You can use Encore’s Comprehensive Help to view
details about various aspects of the application. Comprehensive Help includes a search function, allowing you to
quickly look up the subject of interest.

Once you have installed Encore you can navigate from the host PC’s Windows’ Desktop to access the

The discharge of static electricity can damage some electronic components. Semiconductor devices are
especially susceptible to ESD damage. You should always handle components carefully, and you should
never touch connector pins or circuit components unless you are following ESD guidelines in an
appropriate ESD-controlled area. Such guidelines include the use of properly grounded mats and wrist
straps, ESD bags and cartons, and related procedures.

Electrostatic Discharge (ESD) Handling Notice

Product Care

6000 series devices are essentially maintenance free and require only a minimal amount of care. They should be
treated much like any other high-tech piece of equipment. In general:

Operate the units in ventilated and relatively dust-free environments.
Keep the units clear of harsh chemicals and abrasive elements.
Avoid exposing the products to extreme heat; for example, avoid setting the units near boilers and

furnaces.

Avoid extreme shock and vibration.
Avoid subjecting the units to liquids and extremely fine air particulate, such as silica dust.
Never open the unit. The unit should only be opened by qualified service technicians.

A “common-sense” approach to handling acquisition components will go a long way in protecting them from
inadvertent damage.

Note that you can use lint-free rags and Isopropyl Alcohol (Rubbing Alcohol) to clean the outer surfaces of a 6000
series device.
