Chapter 1 – Introduction - What is TechView?
TechView is a standalone software package that allows a technician to:
Calibrate transmitter(s) either locally (bench configuration) or via
communication with the transmitter’s master controller (RTU).
Perform certain basic configuration operations on a controller, flow
computer, or transmitter, such as changing the local address or
EBSAP group number.
Collect real-time or historical data from the controller, flow
computer, or transmitter.
Start other OpenBSI programs or utilities to perform other activities,
such as the Flash Configuration utility.
Perform on-line edits to signal lists, and to the structure of archive
files in ControlWave-series controllers. (Requires 4.60 or newer
ControlWave firmware.)
Typically, you install TechView software on a portable laptop computer
to allow the technician to bring it to the site of the RTU/transmitter. You
could also install it on a desktop computer in a lab for bench
configuration of a transmitter.
You can use TechView to calibrate the RTD temperature circuitry and
/or the MVT/GPT pressure transducer for the following products:
Note: For minimum system requirements and more detailed installation
instructions, refer to Chapter 2 of the OpenBSI Utilities Manual
(D5081).
1. Log into the workstation with administrative privileges.
2. Insert the OpenBSI CD-ROM in your CD-ROM drive.
3. If your CD-ROM drive has autorun enabled, skip to the next step.
Otherwise, open a DOS prompt with administrative privileges, then
set the folder to the CD root directory, and run the same “open”
command that is in the autorun.inf file on the CD, for example
“demo32.exe openbsi.dbd”. When the CD browser screen appears,
choose the Install OpenBSI option.
A screen reminds you to close all other programs, and warns you
that older OpenBSI versions will be removed. Click Next.

4. A license agreement screen opens. Review the agreement, using the
scroll bar to bring it into view. Click I accept the terms of the
license agreement to proceed. Then click Next.
5. On the next screen, you can specify the user files folder. The system
stores user files such as ControlWave projects, ACCOL files,
recipes, and network files in sub-folders of this folder. Note: If User
Account Control (UAC) is enabled in Windows, you must have
write access to this folder. The default is
C:\ProgramData\Bristol\Openbsi. Use the default or use Browse
to specify a different user files folder. When finished click Next.
6. On the next screen, use the check-boxes to select either Network
Edition (if you purchased the full Network Edition) or BSI_Config
if you are using the free BSI_Config package. These are the
packages which include TechView.

3.1 Starting Your Session:
The configuration information you specify to allow TechView to
communicate with controllers, flow computers and transmitters is stored
in a session file. Session files have a file extension of *.TVS. .
Once you have a session file saved, you can start TechView by standard
Windows™ methods such as typing ‘TechView’ on the command line,
followed by the path and name of the session file (excluding the TVS
extension), or you can drag a TVS file icon onto a shortcut icon for the
TechView application.
Note: If you use the command line option, put quotation marks around
When first starting TechView, by default, the software prompts you to
open an existing session file.

Note: You can change the initial prompt for the user from the
Application Settings dialog box.
Select the session file name you want to open, then click Open.
3.2 Establishing Communications
You can establish communication with all RTUs/transmitters using the
BSAP protocol. For some RTUs you may also use Internet (IP)
protocol.
On the Communication Setup page, choose either BSAP or IP in the
Select Communication Protocol field.
3.2.1 Communication Setup page - BSAP
For BSAP communication, specify the BSAP local address of the RTU
or transmitter:
If you know the BSAP local address, select the Specify Local Address
button, and choose the address using the list box, or enter it directly.
If you want the user to specify the local address at startup, select Ask for Local Address at startup; the user will be prompted to enter the
address.
If you want TechView at startup to attempt to find the local address by
sequentially polling each possible local address (1-127) at the current
baud rate, select Auto Detection.
Most users
don’t need to
adjust these
advanced
parameters.
Choose “BSAP” protocol.

Specify the PC communication port, e.g. COM1, COM2, etc. in the
What port would you like to use field.
Specify the baud rate used by the port in the What baud rate would you like to use field. If you are making an FSK connection to a 4088B,
this must be 1200.
Most users don’t need to adjust the advanced parameters, but if you
need to, click on Advanced Communication Parameters. (Information
on this dialog box is included later in this section.)
Click on Next to proceed to the next page.
3.2.2 Communication Setup page - IP
For IP communication, you must specify the IP address of the RTU.
If you want the user to specify the IP address at startup, select Ask for
IP Address at startup; the user will be prompted to enter the address.
Most users don’t need to adjust the advanced parameters, but if you
need to, click Advanced Communication Parameters. (Information on
this dialog box is included later in this section.)
Most users
don’t need to
adjust these
advanced
parameters.

3.2.3 Advanced Communication Parameters – BSAP
Most users should not edit these parameters. If however, you are having
certain communication problems, you may edit these parameters to
better tune your system.
Click on
[Next>].
Figure 3-4. Advanced Communication Parameters dialog box (BSAP)
This is the rate (in seconds) in which TechView polls the
directly connected RTU.
This is the amount of time, in seconds, that TechView waits
for a response from an RTU or transmitter before assuming
that the unit is dead and will not respond.
These fields specify the number of null characters to insert at
the beginning (front) or ending (back) of a message. Null
characters may be useful in situations where there may be a
momentary delay which could cause the start of a message to
be missed, for example, while a radio link is being activated.
Null characters are also necessary if you are communicating
using a 2-wire RS-485 link, to ensure that DTR is not dropped
prematurely. To determine the delay caused by null packing,
perform the following calculation:
seconds of delay = (number of null characters x 10) / baud

Parameters
On an FSK connection, use “3” back pad for model 4088B.
Use “2” or “3” Back Pad for models 3508 and 3808.
If your communication line uses Ready to Send (RTS) / Clear
to Send (CTS) signals (not to be confused with ACCOL
signals), check this box.
Check this box to prevent TechView from sending a BSAP
time synch message. (Requires OpenBSI 5.8 Service Pack 1
or newer.) The default setting for this is set in the Advanced
Configuration utility. See Appendix E of the OpenBSI Utilities Manual (D5081) for details on the Advanced Configuration
utility.

Description
Enter any modem commands, as well as the dial string
here.
This is the number of attempts TechView makes to dial a
controller (RTU), before declaring that it is off-line. This
must be an integer from 0 to 10.
This is the period of time (in seconds) TechView waits
before declaring a dialing attempt to be a failure.
This is the period of time (in seconds) TechView waits
between sending commands.
This is an initialization string for the modem. TechView
immediately precedes the initialization string with the “AT”
modem command. TechView sends the initialization string
ahead of the dial-up string.
This is the first string TechView sends to the modem when
an attempt is made to hang up.

This is the second string TechView sends to the modem
when an attempt is made to hang up.
This is the number of attempts which will be made to hang
up the modem before declaring a hang-up failure. This
value must range from 0 to 10.
This is the amount of time TechView waits before
declaring an attempt to hang up to be a failure.
This value specifies the amount of time (in seconds) after
which the modem should be hung up if there has been no
communication (other than poll messages) between
TechView and the controller.
If you check this box, TechView will drop DTR in order to
hang up, before sending the hang-up strings, and
TechView will raise DTR before dialing.
Click OK to save the dial-up and hang-up parameters.
3.2.4 Advanced Communication Parameters – IP
Most users should not edit these parameters. If however, you are having
certain communication problems, you can edit these parameters to better
tune your system.
Figure 3-6. Advanced Communication Parameters dialog box (IP)
The UDP Port Number for IP Driver (sometimes known
as the socket number) is used for communication with
RTUs. It is used to split message traffic along different
'streams'. All PCs or RTUs which are to communicate with
each other must have the same UDP Port Number for IP Driver. In a sense, this value is like a common password
which must be known by each node in the network. If no
value is entered, TechView assigns a default value for use
throughout the network when the system is first created.
(Note: Although the term “UDP port” is used, it has no
actual relationship with the physical communication ports.)
Note: The UDP Port Number for IP Driver should never
be 0.
The UDP Port Number for Time Synch is used for time
synchronization of the RTUs. All PCs or RTUs must have
this value defined, or else they will be unable to receive
time synchronization messages. In a sense, this value is
like a common password which must be known by each
node in the network. If no value is entered, TechView
assigns a default value for use throughout the network
when the system is first created. (Note: Although the term
“UDP port” is used, it has no actual relationship with the
physical communication ports.) Note: The UDP Port
Number for Time Synch should never be 0.

3.2.5 Node Setup
Next, you must identify certain characteristics of the unit to which you
are trying to communicate. The appearance of the Node Setup page
varies somewhat, depending upon what type of RTU you are
configuring:
This value specifies (in seconds) how often time
synchronization messages should be sent to IP RTUs.

Certain RTUs (EFM, GFC, XFC) may include a built-in internal
transmitter with sensor (wet end). Some versions of the XFC can
include 2 wet ends. Specify the number of wet ends for this RTU.
If checked, the transmitter’s communication with the BBTI board will
be temporarily suspended, so that a different program can
communicate with the transmitter.
If this ControlWave project has multiple resources, select the
resource which is currently running in the unit.
(Not shown) If communication is with a 3530 TeleFlow-series unit,
specify which of the standard application ACCOL loads (or C load) is
running in the unit. If needed, you can then use the Calibration Signal Configuration button to specify different signal names for
the configuration signals associated with the load. Note: If the load
type you specify here does not match the load type running in the
controller, TechView prompts you to change the load type so that it
does match the one running in the controller.
You can specify a control strategy to be used in conjunction with the
RTU used in this application. For the 33XX line of RTUs, this is the
name of the ACCOL load running in the RTU. For the ControlWave
line of RTUs, this is the name of the .MWT project running in the
RTU. Click Browse to locate the file. Note: 3508 and 3808 Transmitters don’t have a control strategy file.
Web Access
Startup Page
Advanced
Interface Setup
You can optionally specify a default web page for this RTU, which
you may start while you are in TechView. Click Browse if necessary,
to locate it.
Most users use the standard configuration INI files that come with
TechView. Some advanced users, however, may want to customize
the organization of pages within TechView. This button calls up a
dialog box allowing you to identify special configuration files for
TechView. For details on this subject, please see Appendix A of this
manual.
3.2.6 Calibration Setup
This page specifies certain parameters that tell TechView how it will
access the transmitters for calibration.
How many
transmitters does
the application
load support (Wet
ends and
externals)?
Description
Displays the type of node chosen in the Node Setup
dialog box.
This field only applies for BSAP communication
connections.
For 3508 and 3808 series transmitters, checking
“Local” means that TechView will communicate locally
with a transmitter directly connected to the PC, on Level
1 of the temporary BSAP network. For Network 3000
(except for the 3530-series) checking the “Remote” box
means that TechView will communicate with an RTU
directly connected to the PC, on level 1 of the BSAP
network. This RTU has one or more transmitters
connected to it that will be on Level 2 of the temporary
BSAP network. Note: The 3530-series does not support
Remote access.
Note: In Remote Access, if your Network 3000 RTU is
not currently part of a network, i.e. you are working in
the lab, or performing bench testing, you should connect
through the Slave Port. Conversely, if you are working in
the field, with an RTU that is already part of a network,
you should connect through the Pseudo Slave Port.
Note: If you select Remote the Transmitter Setup page
will be added to your Session configuration.
If using the ControlWave Express/EFM/GFC/XFC
series, with multiple transmitters, the application running
in the ControlWave EFM/GFC/XFC must support
multiple meter runs and TechView configures the
transmitter(s) by setting parameters within the RTU’s
multi-run application; and calibration success/failure will
be noted as an audit record in the multi-run application.
You must specify the total number of transmitters (both
internal wet ends, and external transmitters) here.
As Found / As
Left Verification
Signal
Configuration
Note: If you want to use TechView to communicate with
an RTU that doesn’t require any calibration, you can
hide calibration options by setting this to 0. (OpenBSI
5.8 Service Pack 1 and newer.)
If your ControlWave RTU has an internal transmitter that
doesn’t require damping, you can disable damping
functions by selecting this box. (OpenBSI 5.8 Service
Pack 1 and newer.)
When the user enters calibration mode, live values for
differential pressure, static pressure, gage pressure, and
temperature are frozen (i.e. the RTU will collect no new
values from the transmitter, during calibration mode.) A
prompt appears warning the user of this, and giving
them the option of not entering calibration mode.
Similarly, when the user tries to exit calibration mode,
the user will be prompted to confirm that they want to
exit, thereby unfreezing live values. If you check this
box, however, these warning boxes will not appear, and
the user will automatically enter/exit calibration mode. If
you don’t check it, the warning prompts will appear,
giving the user the option of aborting the starting or
exiting of calibration mode.
Check this button to activate the “As Found/As Left”
feature for calibration logs. (OpenBSI 5.8 and newer.)
Note: You cannot use this feature if you are also using
the extended verification feature; they are mutually
exclusive.
If you have modified a standard application with different
calibration signal or variable names, the [Calibration Signal Configuration] button allows you to specify the
new signal/variable names.
If you have modified an application that uses the
extended verification feature for Modbus messages, and
specified different variable names for the extended
verification signal configuration feature, click the
Extended Verification Signal Configuration button to
specify the new variable names. (OpenBSI 5.8 Service
Pack 2 and newer.) Note: Extended verification only
applies to external transmitters. In addition, the
Extended Verification and As Found/As Left functions
are mutually exclusive.
If you have modified a standard application with different
verification signal or variable names, the As Found / As Left Verification Signal Configuration button allows
you to specify the new signal/variable names. (OpenBSI
5.8 and newer.) Note: The As Found/As Left and
Extended Verification features are mutually exclusive.
If you chose Local for Select Transmitter Access, click Finish; if you
chose Remote click Next.
If desired, you can change the Local Address and the Type of the
transmitter from the Transmitter Identification dialog box.
To modify the address or type of a transmitter in the list, either
double-click on the transmitter’s name, or click on the name, and then
click on Modify and make the changes in the Transmitter
Identification dialog box.
Figure 3-10. Transmitter Identification
To add another transmitter to the list, click Add and fill in the fields in
the Transmitter Identification dialog box.
To remove a transmitter from the list, click on the transmitter’s name,
then click Remove.
To remove all of the transmitters from the list, click on Remove All.
Click OK when finished.
When you have finished configuration for the transmitters, click Finish.
Once you click Finish and communications have been successfully
established with the RTU, TechView prompts you for a Username and
Password.
TechView User’s Guide (D5131)
Figure 3-11. SignOn to RTU
Enter the username/password combination, and click Signon. The RTU
must recognize this username/password combination as valid in order
for you to gain access.
Notes:
Some customers may choose to set up a default username/password,
to avoid having to enter it repeatedly. See Application Settings later
in this manual, for details.
If you use TechView to call up web pages, for example, in the
Measurement group, do not sign off from the Sign-On/Off web
page control unless you intend to also exit TechView, since the web
pages, and TechView share the same connection to the RTU. If you
only want to exit web pages, but continue with TechView, just close
the web pages, from the standard windows control, don’t sign off.
If you are unable to sign on to the RTU, because it needs to be
downloaded first, you can do this without logging on. In TechView,
click on Operations > Download First Level Node to call up the
Downloader and download a control strategy file to the RTU. You
can then proceed to download.

Standard sets of configuration/calibration pages specific to each type of
transmitter, or RTU containing a transmitter, are included when you
install TechView.
Based on your choice of node type, these pages load in a series of one or
more groups, accessible via icons on the right hand side of the page.
When you choose a particular group, the associated pages appear on the
screen, or menu items which call them appear, depending upon the
number of pages. Once the group is activated, you can proceed to
perform the calibration, configuration, or online editing for your
RTU/transmitter.
The Calibration group is always required. Additional groups may exist
for other functions. Advanced users can also change the organization of
the pages in groups, by editing TechView initialization files. For more
information on changing these initialization files, see Appendix A –Initialization Files.

Chapter 5 – Calibration Overview
This chapter provides general information on calibration and then
provides procedures for calibrating different devices.
In This Chapter
5.1 Why is Calibration Necessary? ........................................................ 5-1
When a transmitter ships from the factory, it is already factor ycompensated for a specific pressure range. When you install the
transmitter on site, however, the accuracy of the transmitter may have
been affected by environmental conditions (temperatures, atmospheric
pressures, etc.) at that particular site. For this reason you must calibrate
the transmitter. In addition, you must periodically re-calibrate the
transmitter to ensure that it maintains its accuracy.
5.2 Calibration Concepts
You must understand certain concepts and terminology before
performing the calibration procedures:
Measured Variable
Applied Value
The measured variable is the actual “live” process variable reading,
coming from the transmitter. This could be a differential/gage
pressure reading, a static pressure reading, or a resistance
temperature detector (RTD) temperature reading.
Applied values are used during calibration. They represent known
values, which are used as a standard or benchmark from which
other values can be calculated by the transmitter.
For pressure, the applied value is a known pressure, applied from
an external pressure source, to the transmitter.
For temperature, the applied value is a known resistance applied by
the user, by connecting a resistor, in place of the RTD.
Upper Range Limit
(URL) and Lower
Range Limit (LRL)
Issued Nov-2016 Calibration Overview 5-1
Transmitters are ordered with specific pressure ranges. An upper
range limit (URL) and a lower range limit (LRL) are preset at the
factory to define the range of pressures that the transmitter can
TechView User’s Guide (D5131)
Upper Range Value
(URV) and Lower
Range Value (LRV)
(applies to analog
models only)
read. The URL is the maximum value for the pressure, which can
be read by the transmitter. The LRL is the minimum value for the
pressure, which can be read by the transmitter. Any pressure value
which is higher than 105% of the value of the URL or lower than
the value of (LRL -(5% of the URL)) is considered out-of-range
and cannot be considered accurate.
In contrast to the URL and LRL which define the fixed, predefined factory range for the transmitter, the Upper Range Value
(URV) and Lower Range Value (LRV) may be used to establish
the range being measured for the actual process. For example,
suppose the transmitter has an LRL of 0 psi, which corresponds to
4 mA and a URL of 1000 psi, which corresponds to 20 mA, but the
range of values you want to measure is 0 to 500 psi, then the LRV
would be 0 (4 mA) and the URV would be 500 (20 mA).In this
example, the LRV and URV settings represent a 2 to 1 turndown.
There are certain rules to be observed when setting LRV and URV.
The LRV cannot be set below the LRL.
The URV cannot be set above the URL.
URV minus LRV must be greater than 1/20 of the URL.
For more information on LRV/URV, please consult the hardware
documentation for the transmitter.
SPAN
ZERO
MVT
RTD
GPT
The SPAN value is a positive value which (when added to the
ZERO value) defines the highest expected operational value for a
particular measured variable. This could be the same as the URL,
but in some cases, the SPAN value might not equal the URL. For
example, a transmitter having a 2000 psi URL might only be used
over a 0 to 1000 psi range, and so a span calibration at the 1000 psi
point is performed. The minimum value for the span is URL
divided by 20. If, when calibrating the SPAN value for a pressure
transducer, you apply a pressure value significantly less than the
URL, accuracy may be reduced for readings outside of the span.
The ZERO value is the measured variable value that corresponds to
0% of the transmitter’s SPAN, i.e. 4 mA for a 4 to 20 mA range, or
1V for a 1 to 5V range.

This is a periodic check in which you compare the live reading of a
transmitter against a known measurement standard in order to

p
determine if the transmitter measures accurately and remains
properly calibrated. You apply an external source, such as a deadweight tester, to the transmitter and check points along the
measurement curve.
Damping
Damping Time
As Found / As Left
(OpenBSI 5.8 and
newer)
The output damping feature is applicable to ControlWave
EFM/GFC/XFC flow/gas computers, 3508-series Transmitters and
3808-series Transmitters and controls the rate at which the output
responds to a given change of input. It is used to slow down the
output response to a rapid or oscillatory change of the measured
variable.
The period of time during which the indicated value changes only
63% of the difference between the “present measured variable” and
the “present indicated pressure” in one damping time period. It
would take 5 times the DP Floating Point Damping Time for the
“present indicated pressure” to equal the “present measured
pressure” (if a change in the “present measured pressure” didn’t
occur). An increase in the DP Floating Point Damping Time results
in an increased smoothing of the indicated value. Note: In the case
of a model 3530-series unit, if the External Transmitter is a model
3808, Damping Mode is always enabled and can’t be changed;
Damping Time can’t be changed either.
“As Found/As Left” verification is a systematic method to capture
the state of a transmitter, both before and after linearization or
calibration of the transmitter.
At the start of the process, you perform the “As Found”
verification. This determines the current state of the transmitter.
You evaluate the results against a set of limits to determine
whether you need to:
a) leave the transmitter as is
b) perform a physical calibration of the transmitter or
c) take the transmitter out of service and replace it.
You can compare the results to values from the previous “As Left”
verification.
Note: As Found/As Left operations are logged in the audit buffer
at the RTU.
5.3 Before You Begin
Before you start the calibration procedure, there are several things you
need to be aware of.
Calibration in the lab
vs. calibration on site
Issued Nov-2016 Calibration Overview 5-3
Although it is more convenient and recommended to perform this
rocedure using a laboratory setup, calibration can also be performed
TechView User’s Guide (D5131)
on site providing that the connecting line or flange is equipped with a
calibration tap and appropriate shutoff and bypass valves. This added
equipment allows you to feed in an external test pressure source or use
the process pressure as a reference signal. In the latter setup, the
valves are closed to seal a fixed pressure in the connecting line.
Note: Before starting any calibration procedures, make sure that the
unit in question is firmly anchored in its intended operating
position. A different mounting position can affect zero
calibration for some ranges and necessitate re-calibration.
WARNING
Communication
Port
Considerations
Only perform calibration activities if the area is non-hazardous.
Before attempting on-site calibration, carefully check the application. If
the unit in question is operated in a closed control loop configuration,
either the MVT/GPT Pressure Transducer must be isolated from the
process, or the process must be turned off. If this is not done, a critical
process could accidentally be driven into a dangerous region causing
damage to equipment and property, and injury to persons
Note: If you modified your application to use different calibration /
verification signal names, you must identify these within
TechView. See Section 4.5.
Notes:
When performing calibration in the field for a Network 3000
device, use the Pseudo-Slave Port of the RTU, not the Slave Port.
Connecting through the Slave port would force you to break
communications with upper levels of the network. In addition, if
you use the Slave Port, it would receive a node routing table
(NRT) from TechView which would only encompass the locally
connected node, and its transmitters. When the connection is
subsequently restored with the network, this would be an incorrect
node routing table, and communications would still not be possible
with higher level nodes. To avoid these problems, perform
calibration through a Pseudo-Slave Port.
When performing calibration through a ControlWave unit’s port,
you must set its _Px_NRT_DIS system variable to TRUE to avoid
the same problem described above.
When performing calibration through a ControlWave unit’s port,
you must set its _Px_NRT_DIS system variable to TRUE to avoid
the same problem described above.
If you are using Expanded Node Addressing (EBSAP) with
ControlWave, and the ControlWave unit is in a group other than
Group 0, the Local Port MUST be marked as LOCAL via the
System Variable Wizard in ControlWave Designer. Otherwise,
communications will not be possible.

5.4 Equipment Required for Calibration
The equipment required depends on what type of calibration you need to
perform.
5.4.1 Equipment Required For Pressure Calibration
Pressure calibration (static, differential or gage) requires the following
items:
Instrument Mounting Fixture: This fixture must secure the
instrument such that the MVT is positioned identically to its
installation site. GPT equipped units must be positioned vertically.
A Pressure Gauge (must cover the range of the MVT/GPT
Transducer .025% accuracy)
An adequate Pressure Regulator
A Pressure Source (and Interconnect Lines) capable of generating
fixed pressure values equivalent to 0%, and 100% values of
transmitter’s range (URL).
The pressure calibration procedures in this manual require that a text
fixture incorporating these items be used.

reading could be off 0.25 degrees C at 100 ohms, and 0.9 degrees C at 300
ohms. Factory calibration accuracy is 0.05°C at 100°C (212°F) and 0.30°C

readings of 0.000 and 100.000 inH2O, the difference would be

calculated as follows:
5. Click Shift Floating Point Span. The adjusted value will appear in
the Live Value field. If an error occurs, proceed to step 6.
6. If the error message "Correction not allowed, change exceeds +3%
of URL" appears, the problem may be caused by: a) the pressure
source is not accurate; b) an incorrect value was entered; or c) the
zero pressure point was not set accurately. Check out each item and
make corrections as required.

6.2 Calibration of Static Pressure
p
For static pressure, the same pressure must be applied to both the HI and

the HI and LO ports, and a SP value at the HI port.

atmospheric pressure is applied. Click Calibrate Zero, and the Live
Value will be trimmed to be as close to the zero as possible.
2. To Calibrate the span, enter the desired span in the Operating Span
field, then apply a pressure equivalent to the desired span. This
value must be less than or equal to the Data Plate SP URL value.
Then click Calibrate Operating Span. The Live Value will be
trimmed to be as close to the desired span, as possible.
If needed, the span and zero of the SP floating point number may be
shifted a minor amount (+3% of URL) so that it correlates with the
ressure standard used by the external process measuring device. A
correction is achieved by calculating a shift correction factor and
applying it to the floating point number by direct entry.
If it is determined that the difference at zero and upper end of the SP
range is the same, then only a zero shift will be required.
Example: Assume that the URL of the transmitter is 2000 psi
and that it has been calibrated for a 0 to 500 psi range. If the 0
check point was read as 1.200, the difference would be: 0 - 1.200
= -1.200. A zero entry of -1.2 psi would provide the correlation
between the floating point number and the standard of the

Shift field, and click the Shift Floating Point Zero button. After a
moment the reading in the Live Value field will reflect the change.
The attempted entry of values that exceed +3% will result in an error
message.
Should a correlation difference exist at the upper end of the range but
none occurs at the zero end, only a span shift will be required.

reads 0.000 and 497.445 psi for these same points, the difference
is 0 psi at the low end and 2.555 psi at the upper end. The span
shift is calculated as follows: Span Shift = (+ psi error)

8.6 Damping
The output damping feature controls the rate at which the output
responds to a given change of input. It is used to slow down the output
response to a rapid or oscillatory change of the measured variable.
Figure 8-5. Damping tab
The Damping Time is a period of time during which the indicated
value changes only 63% of the difference between the “present
measured variable” and the “present indicated pressure” in one damping
time period. It would take 5 times the DP floating point damping time
8-6 3530 TeleFlow Calibration Issued Nov-2016
for the “present indicated pressure” to equal the “present measured
pressure” (if a change in the “present measured pressure” didn’t occur).
An increase in the DP floating point damping time results in an
increased smoothing of the indicated value.
Note: In the case of a model 3530-series unit, if the external transmitter
is a model 3808, damping mode is always enabled and can’t be
changed; damping time can’t be changed either.
8.6.1 Configuring the Damping Time
1. If this flow computer is handling more than one meter run, first select
the run you want to configure from the Run list box.
2. Enable the damping feature (if it isn’t already active) by clicking on

The “Inputs” page provides for gage pressure calibration of inputs to
remove the effect of sensor zero offset and slope variation. You must
calibrate the zero first.
Gage pressure calibration requires the following items:
Instrument mounting fixture: This fixture must secure the instrument
such that the presure transducer is mounted vertically.
a pressure gauge (must cover the range of the pressure transducer)
an adequate pressure regulator
a pressure source and interconnect lines
A test fixture that incorporates the items listed above may be used. A
typical 3530-series pressure transducer calibration interconnection
diagram is provided, below:
Note: Calibration mode only remains active for the length of time
indicated in the Calibrate Time field. Otherwise, Zero Offset
and Span Factor will be set to 0.000 and 1.000, respectively.
1. First, calibrate the ZERO. You should apply atmospheric pressure
when calibrating the ZERO. Click on Calibrate Zero. The load
calculates a Zero Offset that will be added to the sensor reading to
8-8 3530 TeleFlow Calibration Issued Nov-2016
TechView User’s Guide (D5131)
remove any existing offset at zero pressure. For example, a 1000
psig sensor may be reading 1002 psig with no pressure applied.
After calibration a -2.0 zero offset will be used on the Input Value
to remove the +2 psig offset.
2. To calibrate the span, apply 25% to 100% of sensor URL pressure,
and enter the applied value in the Applied Pressure field, then click
the Calibrate Span button to do a span factor calculation. The load
calculates a Span Factor that will be applied to the Input Value
reading to compensate for slope variation. For example, with zero
offset already calculated and 50 psig applied a 100 psig sensor may
be reading 49 psig because the sensor slope is slightly off. The load
will calculate and apply a span correction factor of 50/49 = 1.0205
to the Input Value to compensate for the slope variation. THIS
CALIBRATION DOES NOT LINEARIZE THE SENSOR INPUT
READING - IT ONLY COMPENSATES FOR ZERO OFFSET
AND SLOPE VARIATION. The result of applying zero offset and
span factor to the Input Value is the Value in Use. The ACCOL
load executes every 15 seconds; so allow time for results to appear.
Note: If desired, you can clear the Zero Offset and Span Factor values
by clicking on Restore Defaults; the offset and span factors are
set to 0.0 and 1.0 respectively.

and want to re-run the verification for a particular test point, click
the Back button. If you want to skip over a test point, click the Skip Test Point button.
The output damping feature controls the rate at which the output
responds to a given change of input. It is used to slow down the output
response to a rapid or oscillatory change of the measured variable.
Figure 9-9. Damping tab
The Damping Time is a period of time during which the indicated
value changes only 63% of the difference between the “present
measured variable” and the “present indicated pressure” in one damping
time period. It would take 5 times the DP Floating Point Damping Time
for the “present indicated pressure” to equal the “present measured
pressure” (if a change in the “present measured pressure” didn’t occur).
An increase in the DP Floating Point Damping Time results in an
increased smoothing of the indicated value.
Note: If the External Transmitter is a model 3808, damping mode is
always enabled and can’t be changed; damping time can’t be
changed either.
9.7.1 Configuring the Damping Time
1. Select the transmitter you want to change the damping time for
using the Transmitter list box. “Wet ends” refer to internal
transmitters; all other transmitters are external.
2. To change the Damping Time enter a new damping time (in
seconds) in the Damping Time field, then click on the Change DP
Floating Point Damping Time button. This writes the new
damping time to your application in the ControlWave.

10.1.1 DP/GP Pressure
Configuration options for the differential pressure variable consist of
setting the damping, selecting the engineering units, and setting lower
and upper range values.
Figure 10-2. Configuring the Differential/Gage (DP/GP) Pressure Variable
1. Click DP/GP Pressure to open the DP/GP Pressure menu.
2. Specify a Damping value from 0.0 (none) to 30.0 seconds. For a
step change in input it takes five times the damping value for the
reading to reach the new input. For example, an input change from
60 inH2O to 70 inH2O will take five seconds when damping is set
to 1. Similarly, an input change from 60 inH2O to 70 inH2O will
take 20 seconds when damping is set to 4.
3. Select the engineering Units for the differential pressure variable.
4. Specify the Lower Range Value (LRV). The LRV should be the
lowest value for the DP/GP variable you want to measure for your
process. This cannot be less than the Lower Range Limit (LRL)
which represents the factory set lowest value for the range of values
the sensor can read.
5. Specify the Upper Range Value (URV). The URV should be the
highest value for the DP/GP variable you want to measure for your
process. This cannot be more than the Upper Range Limit (URL)
which represents the factory set highest value for the range of values
the sensor can read.

1. In the “Select Operation for DP Sensor” box, select Zero
Calibration.
2. To perform the zero calibration, vent the transmitter to atmosphere,
so no pressure is applied. Click on the Calibrate Zero button, and
the Measured Value will be trimmed to be as close to the zero as
possible.
3. To calibrate the span, select Span Calibration in the “Select
Operation for DP Sensor” box, then apply a pressure equivalent to
the desired span. Now enter the pressure you applied in the New
Applied Value field. If the transmitter accepts the New Applied
Value, the value you entered will be displayed in the Target Trim
Value field. This value must be less than or equal to the Sensor
URL value. Click on Calibrate Span. The Measured Value will be
trimmed to be as close to the desired span, as possible. Note: Span
calibration may only be performed successfully if the applied
pressure and span are within +3% of one another.

10.2.3 Calibration of RTD Temperature
Figure 10-10. T tab – Calibration of RTD Temperature
1. Disconnect the regular RTD and connect a 100 Ohm (0.01%)
precision resistor across the RTD terminals (this is equivalent to
32°F).
TechView User’s Guide (D5131)
2. Observe the Measured Value and wait for it to stabilize.
3. Click the Calibrate Zero button to calibrate the RTD zero.
4. Disconnect the resistor of step 1 and connect a precision resistor
across the RTD terminals to represent your desired span.
To calibrate to the default temperature span value of 558 °C (1036
°F) requires a resistance value of 300 ohms +/- 0.01%.
To calibrate the temperature span to any other desired value, you
must know the proper resistance value for that span. You must
calculate this yourself or refer to a 100 ohm platinum RTD chart.
For example, to calibrate the span to the upper range limit (URL) of
the transmitter (660 °C, 1220 °F) requires a 332 ohm resistance +/-
0.01%. After you connect the required resistance, enter the desired
temperature span value in the Custom Span field.
5. Observe the Live Value and wait for it to stabilize.
6. If you connected a 300-ohm resistance in step 4, click the Calibrate
Span (at 300 ohm) button; if you connected any other resistance
value click the Calibrate Custom Span button.
7. Disconnect the resistor, and reconnect the RTD.
Notes:
If, for some reason, you want to return to the calibration that was
performed by the factory, click on Restore Factory Defaults.
To change the reading from the RTD for the 4088B, enter the
desired reading (which should be similar to the actual reading, but
presumably off slightly), and click on Adjust Live Reading.

10.2.2 Batch Editing of Archive Files ............................................. 11-7
Signal lists are a convenient way to organize and view signals used in
your control strategy. For example, you might have a list of
configuration parameters that apply to a particular portion of the control
strategy; or you might have a list containing the current values of
various process variables.
Note: Beginning with OpenBSI 5.8 Service Pack 1, lists can contain
up to 10,000 signals; earlier versions limited this to 5000 signals.
If your controller is running a standard application, created by Emerson,
certain signals will already be stored in signal lists for you to look at.
You may decide, however, that there are other signals in the application
that you want to add to an existing list, or maybe there are signals you
want to remove from a list, because you don’t use them much. These
changes can be made via on-line signal list editing.
