Introduction
1 Before You Start
1.1 Introduction
Field Temperature Blocks (FB150, FB350, and FB660) are designed to be reliable,
stable heat sources that can be used in the eld or laboratory. They offer accuracy,
portability, and speed for nearly every eld calibration application. The instruments
have been designed with the eld user in mind and are easy to use while maintaining
stability, uniformity, and accuracy comparable to some laboratory instruments.
Special built-in features make Field Temperature Blocks extremely adaptable. The
exclusive Voltage Compensation allows the technician to plug into mains power with
voltage from 90 V ac to 250 V ac without degradation to the instrument. The Ambient
Temperature Compensation provides the largest operating range in the industry (0°C
to 50°C) with the largest guaranteed temperature range (13°C to 33°C). The Gradient Temperature Compensation keeps the axial gradient within specication over the
entire temperature range of the instrument and over the specied guaranteed operating temperature range. These combined features along with the rugged design, light
weight, and small size make this line of instruments ideal for eld applications.
Unique Patent Pending safety features make these the safest eld heat sources available. The unique Air Flow Design keeps the probe handle cool protecting delicate
instruments and the user. The Block Temperature Indicator shows the user when the
well temperature is above 50°C letting the user know when it is safe to remove the
insert or move the instrument. The indicator light illuminates when the instrument is
energized and the well is above 50°C. If the instrument is removed from mains power,
the indicator light ashes until the well has cooled to less than 50°C.
The optional “-R” version (“FBXXX-R”) combines the heat source with a built-in
reference.
The Field Temperature Blocks’ controller uses a PRT sensor and thermoelectric modules or heaters to achieve stable, uniform temperatures throughout the block.
The LCD display continuously shows many useful operating parameters including the
block temperature, the current set-point, block stability, and heating and cooling status.
For the -R version, the reference temperature readings are displayed. The display can
be set to show the information in one of eight different languages; English, Japanese,
Chinese, German, Spanish, French, Russian, and Italian.
The instrument’s rugged design and special features make them ideal for the eld or
the laboratory. With proper use, the instrument provides continued accurate calibration
of temperature sensors and devices. Before use, the user should be familiar with the
warnings, cautions, and operating procedures of the block as described in the User’s
Guide.

CE Comments
around the instrument. Overhead clearance of 1 meter (3 ft) is required. DO NOT
place instrument under any structure.
Component lifetime can be shortened by continuous high temperature operation.
DO NOT use uids to clean out the well. Fluids could leak into electronics and damage the instrument.
Never introduce any foreign material into the probe hole of the insert. Fluids, etc. can
leak into the instrument causing damage.
Unless recalibrating the instrument DO NOT change the values of the calibration constants from the factory set values. The correct setting of these parameters is important
to the safety and proper operation of the block.
DO NOT allow the probe sheath or inserts to drop into the well. This type of action
can cause a shock to the sensor and affect the calibration.
The instrument and any thermometer probes used with it are sensitive instruments that
can be easily damaged. Always handle these devices with care. DO NOT allow them
to be dropped, struck, stressed, or overheated.
DO NOT operate this instrument in an excessively wet, oily, dusty, or dirty environment. Always keep the well and inserts clean and clear of foreign material.
The Field Temperature Block is a precision instrument. Although it has been designed
for optimum durability and trouble free operation, it must be handled with care. Al-
ways carry the instrument in an upright position to prevent the inserts from dropping
out. The convenient handle allows for hand carrying the instrument.
If a mains supply power uctuation occurs, immediately turn off the instrument.
Power bumps from brown-outs could damage the instrument. Wait until the power has
stabilized before re-energizing the instrument.
The probe and the block may expand at different rates. Allow for probe expansion
inside the well as the block heats. Otherwise, the probe may become stuck in the well.
Most probes have handle temperature limits. If the probe handle limits are exceeded,
the probe may be permanently damaged. Due to a unique Air Flow Design, Field Tem-
perature Blocks protect the probe handle temperature and provide a safer temperature
handle for the user.
1.5 CE Comments

FBXXX Field Temperature Blocks
CE Comments
8
The instrument was designed specically as a test and measuring device. Compliance
to the EMC directive is through IEC 61326-1 Electrical equipment for measurement,
control and laboratory use.
As noted in the IEC 61326-1, the instrument can have varying congurations. The
instrument was tested in a typical conguration with shielded RS-232 cables.
1.5.2 Immunity Testing
Using Clamp-On Ferrites
For the –R model only, clamp-on ferrites are provided for use in improving its electromagnetic (EM) immunity in environments of excessive EM interference. During EMC
testing we found that ferrites clamped around probe cables for the Reference PRT input reduced the risk the EM interference affects measurements. Therefore, we recommend that the clamp-on ferrites provided be used on the cables of probes attached to
the readout, especially if the product is used near sources of EM interference such as
heavy industrial equipment.
To attach a ferrite to a probe cable, make a loop in the cable near the connector and
clamp the ferrite around half of the loop as shown in the diagram. The ferrite can be
easily snapped open and moved to a new probe when needed.

3.2.4 -R Option Panel (-R models only)
The -R (reference sensor) panel is the readout portion of the instrument and is only
available with -R models.
Figure 7 -R option panel
Reference Thermometer Connection (1)
The 6-pin Lemo smart connector on the front panel allows a reference probe to be attached to the instrument for use with the reference thermometer function of the instrument. The smart connector stores probe calibration coefcients. Using an adapter, the
6-pin Lemo will accept traditional connectors and the probe coefcients can be entered
into the readout or an appropriate characterization curve can be selected through the
user interface (see Section 1.5.2, Immunity Testing, on page 8 for information on using clamp-on ferrites).
A PRT is the only type of probe that is supported by the reference thermometer input.
The PRT (RTD or SPRT) probe connects to the reference thermometer input using a
6-pin Lemo connector. Figure 8 shows how a four-wire probe is wired to the 6-pin
Lemo connector. One pair of wires attaches to pins 1 and 2 and the other pair attaches
to pins 4 and 5 (pins 1 and 5 source current and pins 2 and 4 sense the potential). If
a shield wire is present, it should be connected to pin 3, which is also used for the
memory circuit. Pin 6 is only used for the memory circuit.

5 Controller operation
This chapter discusses in detail how to operate the Field Temperature Block temperature controller and/or thermometer readout using the front control panel. Using
the front panel keys and liquid crystal display (LCD) the user may monitor the well
temperature, set the temperature set-point in °C or °F, monitor the heater output
power, monitor the stability, set the cutout set-point, set the operating parameters, and
congure the communication interface. For the -R model, the user has full control of
thermometer readout functions of the instrument using the front panel keys and the
LCD. A diagram of the full menu structure can be found in Section 4, Menu Structure,
on page 23. When active, menu keys are selected using the soft keys (F1-F4).
5.1 Main Screen
The LCD on the front panel allows direct viewing of the control temperature (actual
well temperature), reference thermometer temperature (-R model only), heating or
cooling power, stability state, current set-point information, and current program information. The temperature displayed is either in °C or °F. The displayed temperature
units can easily be changed by pressing the C/F key on the front panel.
HEAT SOURCE TEMPERATURE
This is the temperature of the block as measured by the control sensor. The controller
heats or cools the block to force the control temperature equal to the set-point.
SET-POINT (SETPT)
This is the current set-point.
REFERENCE TEMPERATURE (REF) (-R model only)
This is the temperature measured by an external reference thermometer attached to the
Reference Thermometer 6-pin Smart Lemo input.
CONTROL - STAB (Stability)
This shows the stability of the block. When the stability is within the set limit this line
is at.
CONTROL - HEAT/COOL
This shows the relative heating or cooling power (duty cycle) in percent.
HEATING, COOLING, CUTOUT
This shows the status of heating or cooling or the cutout when activated. The bar graph
indicates the relative heating or cooling power.

5.2 Main Menu
The MAIN MENU is accessed through the MENU button and allows access to all
main submenus. The submenus allow the user to setup the instrument as desired and to
change system parameters as needed.
5.2.1 Temp Setup
The TEMP SETUP menu contains Field Temperature Block functions related to temperature setup.
5.2.1.1 Setup
5.2.1.1.1 SCAN RATE
The SCAN RATE parameter can be set such that when the set-point is changed, the
Field Temperature Block heats or cools at a specied rate, degrees per minute, (°C/min
or °F/min) until it reaches the new set-point.
The Scan Rate can be set from 0.1 to 500 °C/min (0.2 to 900 °F/min). However, the
maximum scan rate is limited by the natural heating or cooling rate of the instrument,
which will be less than the maximum setting, especially when cooling.
The Scan Rate can be adjusted using the arrow keys. Once the scan rate has been set,
press “ENTER” to set the new scan rate.
5.2.1.1.2 STABLE LIMIT
NOTE: The Field Temperature Block should not be expected to operate better
than the stability specification set forth in the Specifications section of this
guide. Therefore, the minimum setting of the stability limit should not be less
than the stability specification.
The STABLE LIMIT parameter allows the instrument to notify the user when it has
achieved the stability limit set in this parameter. There are two notications: visual
and audible. The visual notication is always active. When the instrument is operating
within the stability limit, the stability graph on the main screen remains at once the
instrument is within the given specication, otherwise the graph indicates the instrument is not yet stable. The audible, if enabled, alerts the user once per set-point when
the instrument achieves the set stability limit. Use the arrow keys to set the desired
stability limit and press “ENTER” to accept the new stability limit.
Example:
A specic calibration process requires the instrument to operate within ±0.1°C. “0.1”
would be entered into the stability limit parameter. When the instrument’s stability is
within ±0.1°C, the graph is at and the audible alarm (if enabled) noties the user that
the instrument is operating within ±0.1°C. Use the arrow keys to set the desired stability limit and press “ENTER” to accept the new stability limit.

Main Menu
5.2.1.1.3 STABLE ALARM
The audible alarm described in STABLE LIMIT is turned on or off using the STABLE
ALARM parameter. Select the either “Enable” or “Disable” using the left or right arrow keys and press “ENTER” to accept the selection.
5.2.1.2 CUTOUT
The view CUTOUT contains the Cutout functions of the instrument.
5.2.1.2.1 SOFT CUTOUT
The SOFT CUTOUT is user settable. As a protection against software or hardware
fault or user error, the block is equipped with the adjustable cutout device that shuts
off power to the heat source if the well temperature exceeds a set value. It is factory
set as a default ten degrees above the high limit of the instrument. The user should
set the Soft Cutout according to the temperature limits of the probes being calibrated.
The Soft Cutout can act as a safety barrier to protect probes from being over heated
to temperatures beyond their specied temperature limits if the Soft Cutout is set appropriately for probes under test. This feature protects the instrument and probes from
excessive temperatures.
If the cutout is activated because of excessive well temperature, power to the heat
source shuts off and the instrument cools. The heat source remains in cutout mode
and active heating and cooling is disabled until the user manually resets the cutout. If
the over-temperature cutout has been triggered, the instrument displays “CUTOUT”
above the duty cycle bar graph, which indicates a cutout condition. The instrument
remains in cutout mode until the temperature is reduced and the cutout is reset. The
well temperature must drop a few degrees below the cutout set-point before the cutout
can be reset.
For safety reasons, the cutout only has one mode — manual reset. Manual reset mode
means the cutout must be reset by the operator after the temperature falls below the
set-point.
The SOFT CUTOUT parameter can be set to any temperature over the range of the
instrument. The cutout should be set within 5-10° of the safety limit of the equipment
being calibrated or used with the Field Temperature Block.
NOTE: CUTOUT RESET: If the Field Temperature Block exceeds the
temperature set in the soft cutout menu or if it exceeds the maximum operating
temperature of the instrument, a cutout condition occurs. If this happens, the
instrument enters cutout mode and will not actively heat or cool until the user
resets the instrument.
To reset the cutout, the instrument temperature must cool to lower than the cutout setpoint. Once the instrument has cooled the user may reset the instrument by pressing
“SET PT.” and pressing “ENTER” to engage instrument.

Main Menu
and “COEF B4”. These should be set with the corresponding values that appear on
the calibration certicate of the PRT. The parameter “RTPW” takes the triple point of
water resistance, often labeled “R0.01” or “R(273.16K)” on the certicate. Parameters
“COEF A”, “COEF B”, “COEF C” take the an, bn and cn coefcients where n is a
number from 7 to 11. Parameters “COEF A4” and “COEF B4” take the a4 and b4 coefcients on the certicate. Any ITS-90 parameter of the instrument that does not have a
corresponding coefcient on the PRT’s certicate must be set to 0.
The following table (Table ) shows which parameter to set for each of the coefcients
that may appear on the certicate. The example that follows demonstrates how to set
the ITS-90 parameters for certain cases.
Table 4 Matching Certificate Values to ITS-90 Coefficients
ITS-90 Coefficient Certicate Value
COEF A a7, a8, a9, a10, or a11
COEF B b7, b8, b9, or 0
COEF C c7 or 0
COEF A4 a4

Digital communication interface
Wiring
6 Digital communication interface
The Field Temperature Block is capable of communicating with and being controlled
by other equipment through the RS-232 digital interface.
With a digital interface the instrument may be connected to a computer or other equipment. This allows the user to input the set-point temperature, monitor the temperature,
communicate with the readout to obtain measurement data, control operating conditions and access any of the other controller functions, all using remote communications equipment. The RS-232 serial interface allows serial digital communications
over fairly long distances. With the serial interface, the user may access any of the
functions, parameters and settings discussed in this section.
6.1 Wiring
The serial communications cable attaches to the instrument through the DB-9 connector at the front of the instrument. Figure 14 on next page, shows the pin-out of this
connector and suggested cable wiring. To eliminate noise, the serial cable should be
shielded with low resistance between the connector (DB9) and the shield.
6.1.1 Setup
Before operation the serial interface must rst be set up by programming the BAUD
rate and other conguration parameters. These parameters are programmed within
the communications menu. The serial interface parameters can be accessed from the
main menu by MENU|SYSTEM MENU|SYSTEM SETUP|COMM SETUP|. For more
information on the serial interface parameters, see Section 5.2.3.1.2COMM SETUP on
page 33.
6.1.2 Serial Operation
The serial communications uses 8 data bits, one stop bit, and no parity. The setpoint and other commands may be sent via the serial interface to set the temperature
set-point and view or program the various parameters. The interface commands are
discussed in the “Digital Interface” section.
FBXXX Field Temperature Block
Command Syntax
44
Figure 14 RS-232 wiring
6.2 Command Syntax
Field Temperature Blocks accept commands for setting parameters, executing functions or responding with requested data. These commands are in the form of strings of
ASCII-encoded characters. As far as possible, the Field Temperature Block command
syntax conforms to SCPI-1994. One notable exception is that compound commands
are not allowed as explained below.
Commands consist of a command header and, if necessary, parameter data. All commands must be terminated with either a carriage return (ASCII 0D hex or 13 decimal)
or new line character (ASCII 0A hex or 10 decimal).
Command headers consist of one or more mnemonics separated by colons (:). Mnemonics may use letter characters, the underscore character (_), and possibly numeric
digits as well. Commands are not case sensitive. Mnemonics often have alternate
45
Digital communication interface
Commands by Function or Group
forms. Most mnemonics have a long form that is more readable and a short form consisting of three or four characters that is more efcient.
A mnemonic may end with a numeric sufx that species one of a set of independent
function blocks such as input channel data paths. If a numeric sufx is omitted when a
particular block must be specied, an error is generated (“Header sufx out of range”).
Query commands are commands that request data in response. Query commands have
a question mark (?) immediately following the command header. Responses to query
commands are generated immediately and placed in the output buffer. Responses are
then transmitted automatically over the RS-232 port. Responses are lost if not read
before the next command is received.
Some commands require parameter data to specify values for one or more parameters.
The command header is separated from the parameter data by a space (ASCII 20 hex
or 32 decimal). Multiple parameters are separated by a comma(,).
Field Temperature Blocks do not allow compound commands (multiple commands per
line separated with semicolons). All commands are sequential. The execution of each
command is completed before subsequent commands are processed.
6.3 Commands by Function or Group
In this section, the commands are arranged into the following groups:
Calibration Commands – commands for Field Temperature Block calibration
parameters.
Main Screen Commands – commands for parameters displayed on the main screen.
Program Commands – commands for program setup and status.
Reference Commands – commands for accessing reference thermometer parameters.
Setup Commands – commands for setting up communication, display, password,
measure, and operation parameters.
System Commands – commands to report and change the status of the instrument.
Temperature Commands – commands for control temperature and cutout functions.

6.4 Serial Commands - Alphabetic Listing
Each command description provides the structure (long and short format), a description of the command purpose, a command example, an example of what the command
returns (as applicable to query commands), and notes specic to the command. The
following apply to each group of commands:
Numeric data, specied by the mnemonic, <num>, uses ASCII characters to
represent numbers. Numbers may contain a plus or minus (‘+’ or ‘-’) sign,
decimal point (‘.’), and exponent (‘E’ or ‘e’) with its sign. If a fractional
component is received when only an integer is required, the number is rounded
to the nearest integer without any resulting error message. The mnemonics DEF,
MIN, and MAX are often acceptable for the default, minimum, and maximum
value respectively. Unit sufxes, such as V or OHM, can be appended to
numeric parameters and are accepted without error but ignored.
Unrecognized commands or commands with incorrect syntax or invalid
parameters generate error messages in the error queue.
Upper case letters designate syntax that is required when issuing the command.
Lower case letters are optional and may be omitted.
< > indicates a required parameter.
[ ] indicates optional parameters.
( ) indicates a group of parameters that must be used together.
For query commands, specifying the MIN, MAX, or DEF parameter causes
the instrument to respond with the minimum, maximum, or default setting
respectively.
For set commands, specifying the MIN, MAX, or DEF parameters causes the
instrument to use the minimum, maximum, or default setting respectively.
‘|’ indicates alternate parameter values.
<n> indicates a number is required.
<num> indicates numeric value is required.
<prog> indicates a program number (SEQ<n> or SWIT<n>) is required.

Troubleshooting
7 Troubleshooting
This section contains information on troubleshooting.
In the event that the Field Temperature Block appears to function abnormally, this
section may help to nd and solve the problem. Several possible problem conditions
are described along with likely causes and solutions. If a problem arises, please read
this section carefully and attempt to understand and solve the problem. If the Field
Temperature Block seems faulty or the problem cannot otherwise be solved, contact
an Authorized Service Center for assistance. Be sure to have the instrument model
number, serial number, and voltage available.
Table 8 Troubleshooting, problems, causes and solutions
Problem Causes and Solutions
The instrument does not power upCheck the fuses. If a fuse blows, it may be due to a power surge or a
component failure. Replace the fuse once. DO NOT replace the fuse
with one of a higher current rating. Always replace the fuse with one
of the same rating, voltage, and type. If the fuse blows a second time,
it is likely caused by failure of a component part.
Check if the circuit breaker has tripped. Press the button to reset the
circuit breaker. If the circuit breaker continues to trip repeatedly, there
is likely a failure of a component part. Contact an Authorized Service
Center.
Power Cord. Check that the power cord is plugged in and connected
to the instrument.
AC Mains Power. Insure the circuit supplying power to the instrument
is on.
The display is blank
The instrument powers up:
FB150 – fan turns on, FB350
and FB660 – the power relay
clicks, but the display remains
blank
Contrast. Check the screen contrast. Toggle the down arrow key to
see if the screen contrast lightens.
If the contrast is not the issue, contact an Authorized Customer
Service Center.
The instrument heats slowly Scan Rate. Check the Scan Rate settings. The Scan Rate may be set
with too low a rate per minute for the current application.
If the display shows an
abnormal temperature
The sensor is disconnected, open or shorted. Please contact a
Service Center for further instructions.
If the display shows cutout Cutout. If the Temperature Block exceeds the temperature set in the
soft cutout menu, or if it exceeds the maximum operating temperature
of the instrument, a cutout condition occurs. If this happens, the unit
enters cutout mode and will not actively heat or cool until the user
issues the command to clear the cutout or resets the instrument
using the SET PT. key to clear the cutout mode and activate the
instrument.
Reset. The software cutout may need to be adjusted for the
application. Check and adjust the cutout setting by entering CUTOUT
menu: MENU|TEMPSETUP|CUTOUT.

Problem Causes and Solutions
Temperature readout is not
the actual temperature of the
well OR Incorrect temperature
reading
Operating Parameters. Insure that all operating parameters for the
Temperature Block, reference thermometer, and/or probe parameters
match the Report of Certication that was sent with the instrument
and/or probe.
Electrical Interference. Look for sources of electrical interference,
such as motors, welders, generating equipment nearby, or ground
loops. Try shielding wires, removing ground loops, or changing
location.
(FB150) Probes stuck in the
well at low temperatures
Moisture. If the Temperature Block has been used at low
temperatures for extended periods of time, moisture may have built
up in the well forming ice at low temperatures. Set the temperature
high enough to melt ice to remove probes. Set the set-point to
+100°C and allow the moisture to evaporate out of the system.
(FB150) Insert stuck in well If maintenance has not been performed on the insert as described
in the Maintenance Section and the insert cleaned periodically, hard
water build-up on the insert may cause it to stick.
Have the unit in a cold environment – less 21°C. Set the unit to
100°C. While the unit is heating, at approximately 50°C to 70°C, pull
on the insert.
If this does not remove the insert, contact an Authorized Service
Center.

Maintenance
Field Temperature Block Performance Analysis
8 Maintenance
The Field Temperature Block has been designed with the utmost care. Ease of operation and simplicity of maintenance have been a central theme in the product development. With proper care, the instrument should require very little maintenance.
Avoid operating the instrument in an oily, wet, dirty, or dusty environment. Operating
the instrument in a draft-free environment facilitates improved performance of the
instrument.
If the outside of the instrument becomes soiled, it may be wiped clean with
a damp cloth and mild detergent. Do not use harsh chemicals on the surface
which may damage the paint or plastic.
It is important to keep the well of the block clean and clear of any foreign
matter. DO NOT use uid to clean out the well.
The instrument should be handled with care. Avoid knocking or dropping the
block.
The removable inserts can become covered with dust and carbon material. If the
buildup becomes too thick, it could cause the inserts to become jammed in the
wells. Avoid this build up by periodically bufng the inserts clean.
If an insert should be dropped, examine the insert for deformities before
inserting it in the well. If there is any chance of jamming the insert in the well,
le or grind off the protuberance.
DO NOT allow the probe stems to drop into the well or harshly impact the well
bottom. This type of action can cause a shock to the sensor.
If a hazardous material is spilled on or inside the instrument, the user is
responsible for taking the appropriate decontamination steps as outlined by the
national safety council with respect to the material.
If the mains supply cord becomes damaged, replace it with a cord of the
appropriate gauge wire for the current of the instrument. If there are any
questions, contact an Authorized Service Center for more information.
Before using any cleaning or decontamination method, other than those
recommended by Beamex, users should check with an Authorized Service
Center to insure the proposed method will not damage the equipment.
If the instrument is used in a manner not in accordance with the equipment
design, the operation of the instrument may be impaired or safety hazards may
arise.
The over-temperature cutout should be checked every 6 months to see that
it is working properly. In order to check the user selected cutout, follow the
controller directions for setting the cutout. Set the instrument temperature
higher than the cutout. Check to see if the display shows cutout and the
temperature is decreasing.

Accuracy Drift
The display temperature of the instrument will drift over time. This is due to a variety
of factors affecting the temperature control PRT. Any PRT is subject to changes depending on how it is used and the environment it is used in. This is no different for any
PRT in a calibration application. In addition, manufacturing variables in the sensing element itself can result in greater or lesser impact from use and environment. Oxidation
and contamination from the sensor’s environment will create changes requiring new
calibration constants depending on the temperature range and normal operation of the
instrument. Oxidation and contamination are generally not factors when Field Temperature Blocks are used exclusively below 200°C. Oxidation can form in the body of
the PRT platinum sensor wire in the range of 300 °C to 500 °C. Contamination is primarily a problem following prolonged use above 500°C. Additionally, vibration from
handling or transportation will strain the delicate PRT element, changing its resistance.
Some of this strain may come out by annealing at a slightly higher temperature than
the instrument is typically used at. It is recommended to avoid unnecessary temperature cycling. Cycling the temperature up and down between minimum and maximum
temperatures excessively may also cause strain on the PRT element.
Effects from control sensor drift may be avoided by using an external temperature
reference. In the case that the calibration of the display value is required, a program of
monitoring and recalibration must be implemented, just as with any calibration standard. Regularly check the accuracy of the Field Temperature Block with an adequate
temperature reference and keep records as a part of your instrument maintenance routine. When the accuracy drifts to a point where it is no longer acceptable, then have the
instrument recalibrated. Your records will provide data for determining a calibration
interval appropriate for your history of use and accuracy requirements.
Stability
The stability specication of the Field Temperature Block was determined under laboratory conditions of steady ambient temperature and air ow. While this instrument
has been designed to minimize ambient effects, they will still have some effect. For
the best results, avoid quickly-changing ambient temperatures and drafty conditions.
Axial Uniformity
Field Temperature Block axial uniformity should be checked periodically. Use the
process outlined in EURAMET/cg-13/v.01 or a similar process. If the axial uniformity
has changed outside the limits set by the user’s uncertainty budget, adjustment of the
axial gradient may be undertaken by trained personnel.
