Chapter 1: Introduction
Bring world class accuracy to your facility. Sierra’s CalTrak
on the market today. With increased demand for higher flows of process gas, there is a requirement to validate and
calibrate high flow gas meters and controllers. Designed to replace aging bell provers, the XL meets that need with an
impressive standardized accuracy of +/- 0.25% of reading over a flow range of 5 slpm to 500 slpm or +/- 0.45 % from
15 slpm to 1500 slpm.
The flow cell is fitted with low mass borosilicate glass pistons with a low friction coating that oscillate between two
detectors to quickly and accurately measure gas flow rates. The design of the CalTrak allows for increased flexibility
and speed of reading.
Flow measurements can be taken manually (one reading at a time), or automatically in continuous mode. CalTrak
calibrators offer digital communications via RS-232 and USB and come with our CalSoft
suite.
This manual will provide the information needed to operate your CalTrak XL. If at any time you have questions
regarding its operation, please contact Sierra through our web site (www.sierrainstruments.com) or call us at
800.866.0200 to speak with a member of our professional customer service staff.

Warnings!
The CalTrak XL is not intrinsically-safe and is not for use with explosive or
flammable gases, or for use in explosive environments. If you choose to calibrate
explosive or flammable gases with yo ur CalTrakCalTrak XL, please follow yo ur
organization’s laboratory safety p ro cedures, which typically require operation within
an inert atmosphere. To enable use in an inert atmosphere, your CalTrak XL has
two (2) 1/4” gas Purge fittings, located on its right side, and i ts electron ics are
isolated from the gas flow stream, contained within an internal, partitioned
compartment. The CalTrak 800 is not designed for gas flows above the rated
specifications of the flow cell in use. Please consult the product specification on the
inside front cover of the manual for more information regarding acceptable gas flow
ranges or visit our website at www.sierrainstruments.com for the most current
product specifications
The CalTrak XL is not designed to be pressurized above 45 psiA (3102 mbarA) or
for gas flows above 1500 Lpm. If pressurization reache s 45 psiA (3102 mbarA), the
following warning will appear on the dis play on the main control panel:
OVERPRESSURE! If this occurs, remove the overpr essure situation, then choose
“Reset” from the LCD display to clear this warning.
The CalTrak XL does not contain user-serviceable parts and must be returned to
Sierra for maintenance.

Chapter 2: Operating Your CalTrak XL
Connections
Your CalTrak XL should be placed on a steady, secure work surface. For optimum stability, the CalTrak XL has
self- adjusting feet at its base.
Locate both the Inlet (pressure) and Outlet (suction) fittings (see Figure 1) and remove their protective caps.
Maintain only minimum amount of tubing necessary between your CalTrak XL and the flow source. As with any
primary standard, the more internal (“dead”) volume between your CalTrak XL and the flow restrictor (MFC, needle
valve, or sonic nozzle), the more uncertainty (error) is added to the calibration process.
You’re now ready to make the following connections (as needed), using Figures 1 and 2 as reference.
Power
Plug your AC power adapter (supplied) into an AC wall outlet, and attach its DC output cord to your CalTrak XL’s
rear DC Power 12VDC, 3A connection.
Valve Actuation Air Source
Your CalTrak XL’s internal valve actuates by air pressure, and must be connected to a filtered oil free air source of at
least 80 psi (5516 mbar) and no higher than 100 psi (6895 mbar). Using tubing (not supplied) and the 1/4 inch
(6.35mm) Swagelok Valve Actuation Fitting on the rear of the unit, connect your laboratory air to your CalTrak XL.
Turn on the air source, and verify that the pressure is between 80 and 100 psi (5516 and 6895 mbar) (pressure gauge not
supplied).
Inlet (Pressure) and Outlet (Suction) Fittings
When using a pressure flow source, connect the gas flow to the 1.5 inch (38.1 mm) Swagelok®
fitting labeled Inlet – Pressure.
When using a suction flow source, connect the gas flow to the 1.5 inch (38.1 mm) Swagelok
fitting labeled Outlet – Suction.
Your CalTrak XL’s internal pressure transducer is rated at 45 pisa (3102 mbara) maximum, or 5.3 psi (365 mbar)
more than typical ambient pressure. When taking standardized flow measurements, we recommend that any tubing
or exhaust system connected to your CalTrak XL’s outlet fitting have a maximum pressure drop of 3 psi (207 mbar).
When taking volumetric flow measurements, there should be no significant pressure difference (such as the pressure
drop of restrictive tubing or filters) between your CalTrak XL and the point in the flow stream that is of interest (i.e.,
at its inlet or outlet fitting). If there is a significant pressure difference, there will also be a corresponding volumetric
flow difference (from the Ideal Gas Law). In that case, your CalTrak XL’s indicated volumetric flow should be
adjusted by a factor of the absolute pressure at your CalTrak XL, divided by the absolute pressure at the point of
interest.
®

Page 9
Overpressure Exhaust
When your CalTrak XL completes a flow measurement, its internal valve opens, releasing the gas from the flow cell and
enabling the piston to drop to the bottom (reset). If for any reason the valve doesn’t open, the piston will move to the top
of the flow cell and a safety switch will automatically reset the CalTrak XL. If for any reason the valve doesn’t open, the
piston will remain at the top of the flow cell and pressure will build. To prevent over-pressurization of the flow cell, your
CalTrak XL’s has an overpressure sensor that will reset the unit. Additionally the CalTrak XL has a mechanical pressure
relief valve that exhausts the gas if over pressurization occurs through a 1/2-inch Swagelok
®
fitting (Overpressure
exhaust). If this fitting is currently open to ambient and you don’t want the gas to vent to atmosphere, you should connect
a direct line from this fitting to your exhaust system; or, if your CalTrak XL is already directly connected to your exhaust
system, you can “tee” a line from the Overpressure Exhaust fitting to your exhaust line.
Purge Fittings
Your CalTrak XL is not intrinsically-safe for use with explosive or flammable gases (see About Your CalTrak XL
– Warnings). If you choose to calibrate explosive or flammable gases with your CalTrak XL, please follow your
organization’s laboratory safety procedures, which typically require operation within an inert atmosphere. To
enable use in an inert atmosphere, your CalTrak XL has two (2) ¼-inch (6.25 mm) gas Purge fittings, located on
its right side, and its electronics are isolated from the gas flow stream, contained within an internal, partitioned
compartment.
Please note that electric current is still present within your CalTrak XL’s gas flow stream, at the pressure sensor
and temperature transducer.

Getting Started
To turn on your CalTrak XL, press the On/Off button in the lower right corner of the control panel for one
second. To turn it off, press and hold the On/Off button for three seconds.
When turned on, your CalTrak XL’s LCD displays an opening screen indicating the product name, model number
and flow range, and its cooling fan will turn on.
Navigating through your CalTrak XL’s menu screens is easy and intuitive – simply use the four directional arrows on
the control panel for toggling between menu options (right, left, up, down). Your location within each menu or menu
item is highlighted (shaded). A menu item in angle brackets (< >) indicates that multiple options exist for that item;
these options are displayed when that item is selected. To select highlighted or bracketed items, press ENTER at the
center of the navigational display on the control panel.
When you’re ready, visit the SETUP menu and take some time to explore your CalTrak XL’s many user-definable
settings (see Setup).
Customizing Your Calibration
Your CalTrak XL’s calibrations may be customized and automated for your convenience. To customize each option,
move between menu selections using the up and down arrows. When a selection is highlighted, use the right and left
arrows to toggle between your choices for that selection. Press CONFIRM to save any changes and return to SETUP,
or press EXIT to return to SETUP without saving any changes.
Setup
From the initial screen, choosing SETUP gives you access to many customizable options. If at any time you’d like to
return your CalTrak XL to its factory default settings, navigate to Preferences, set Default Settings to “Yes” and then
Confirm the changes. In each setup sub-menu, selecting CONFIRM applies the settings and returns to the main setup
menu. Selecting EXIT returns to the main menu retaining the settings as they were originally.
Readings. Select Volumetric flow or Standardized flow (volumetric flow corrected to specified temperature and
pressure conditions, for calibrating instruments that read in mass flow, such as MFCs). Choose your preferred
number of measurements in the average, from 1 to 100. If you’d like a delay between flow measurements (i.e., in
order to time-profile MFCs to verify their long-term performance), set the “Time Between” from 1 to 60 minutes.
As applicable, change the Sensor Factor from its default value of 1.000 to the value provided by the MFC or
MFM manufacturer (see Using Sensor Factors).
Units. Depending on whether you’ve selected Volumetric or Standardized flow in the Readings menu, you may
view flow measurements in liters or cubic feet (all units are per minute). Choose to view pressure in mmHg, kPa or
psi, and choose to view temperature in Celsius or Fahrenheit. If you’re measuring standardized flow, enter the
temperature to which the gas flow volume will be standardized depending on the application. Pressure
standardization is not adjustable, and is always 101.325 kPa, 760 mmhg, or 14.696 PSI of absolute pressure.

representative or your Sierra sales representative
.
Taking Measurements
Once you’ve finished customizing your CalTrak XL’s SETUP and have confirmed your changes, select MEASURE
to begin a set of measurements. MEASURE gives you access to the main menu, where you can choose between the
following flow measurement options:
Single. Each time the “Enter” button is pressed, one measurement is taken.
Cont. When the “Enter” button is pressed, measurements continue automatically until stopped by the user.
Burst. A single series of measurements is taken until the number of readings in the average is met.
To take a flow measurement, select the type of flow measurement you want, and then press ENTER. Your CalTrak
XL will begin taking flow measurements. When taking flow measurements, the previous measurement, the running
average of all measurements and the number of measurements in the average are provided simultaneously. The flowcell viewing window lights each time the piston rises, and you will hear the internal valve clicking open and closed at
the beginning and end of each flow measurement.
You can stop flow measurements at any time by choosing either PAUSE or RESET. PAUSE terminates the flow measurement but leaves the flow results on the screen and returns to the measurement menu. The set of measurements
may be resumed where they were stopped by selecting SINGLE, CONT., or BURST. You may switch between
continuous and burst modes at will but once single readings are selected RESET must be selected once or twice to
return to the measurement menu to choose continuous or burst modes. RESET clears the screen, resets the average
counter to 0, and returns to the measurement menu.
From the measurement menu, selecting EXIT returns the main menu. Choosing SETUP in the main menu allows
you to further customize your CalTrak XL’s operation.
Using Sensor Factors
Your CalTrak XL is factory-calibrated with nitrogen or purified laboratory air, although you can run other gases,
provided they are noncorrosive, noncondensing and noncombustible (like most primary standards, your CalTrak XL is
not intrinsically-safe).
When calibrating an MFC or MFM using a surrogate or proxy gas (meaning the MFC or MFM was originally
calibrated by the manufacturer for a gas other than what you are currently using), refer to the manufacturer’s sensor
factor.
To enable your CalTrak XL to scale its actual flow measurements to match the adjusted flow from the MFC or
MFM, input the sensor factor into the CalTrak XL before calibrating the MFC or MFM (see SETUP – Readings).
Because a sensor factor other than your CalTrak XL’s default value of 1.000 modifies the actual flow to a
“reported” flow, an exclamation mark (!) will appear next to any CalTrak XL measurement that is being adjusted
according to a sensor factor when your display is set to Zoom (see SETUP, Preferences, Magnification). If your
display is set to Detail, then no exclamation point appears. Rather, the sensor factor (SF) will be displayed, along
with its value on the measurements screen along with the individual flow measurements.

Chapter 3: Notes
Out of Range!
If your Device Under Test is generating more flow than your CalTrak XL’s rated flow range of 1500 liters per minute,
the “Out of Range!” warning appears when you attempt to take a flow measurement. Immediately lower or disconnect
the flow source. When the flow is within the proper range, either choose “Reset” from the LCD display to clear the
last measurement, or try to take another flow measurement.
You may verify your CalTrak XL’s flow range by navigating to SETUP, then About.
Over Pressure!
If your CalTrak XL has an internal pressure that is greater than 49 psiA (134.4 kpaA, 1008 mmHgA), the
“Over Pressure!” warning appears. This can occur before or during a flow measurement. If the CalTrak XL is in the
process of taking a flow measurement, the unit will open the valve; the piston will reset, and display the “Over
Pressure!” warning. You will need to determine the source of the over pressure. This is most likely caused by a
restriction in the flow path. It can also be caused by a faulty sensor allowing the piston to go to the top without
resetting. When the source of the restriction is cleared, pressing any key will clear the fault.
Program
The recessed Program button, located on the rear of your CalTrak XL, enables firmware updates. To update your
CalTrak XL’s firmware (available from our website www.sierrainstruments.com ), connect your serial cable
(supplied) to your CalTrak XL’s RS-232 serial port and to the serial port of your PC, then hold the Program button
down while pushing the recessed Reset button, also on the rear of your CalTrak XL.
Reset Function
If your CalTrak XL fails to respond to push-button commands, try resetting the unit by pressing the reset button on the
back. This can be done easily with a bent paper clip. Please note that resetting your CalTrak XL will not affect your
user settings. However, if you are in the middle of a calibration, your CalTrak XL will return to the initial
measurement phase and you’ll need to initiate a new flow measurement.
Storage
To store your CalTrak XL for an extended period, please follow these guidelines:
Always store it in a clean, dry place
Disconnect your lab’s air supply from its Valve Actuation fitting
Cap its Inlet and Outlet fittings

Chapter 4: Annual Maintenance and Calibration
Your CalTrak XL is engineered to provide years of reliable service, with appropriate care and maintenance.
Sierra recommends annual calibration by an ISO 17025-accredited laboratory, such as Sierra’s Monterey, California
location, to help ensure the best possible flow measurements, meet regulatory requirements and provide a bulletproof
audit trail in the event of litigation. Should you encounter any problems with your CalTrak XL, immediately contact
Customer Service.
Recertification
Your CalTrak XL is a precision measuring standard with moving parts machined to extremely close tolerances.
Various environmental factors, product wear, drift of the temperature sensors and pressure transducers or inadvertent
damage may adversely affect your CalTrak XL’s measurement accuracy or general performance.
For these reasons, we highly recommend having your CalTrak XL annually verified and serviced by our experienced
personnel in our accredited ISO 17025 metrology laboratory, located in New Jersey, USA.
For those applications subject to regulatory or ISO requirements, verification by our accredited laboratory provides
you with assurance of measurement integrity. Please note that while many accredited gas flow measurement
laboratories may be capable of properly verifying the accuracy of your CalTrak XL, Sierra is the only authorized
service center in the USA for Sierra CalTrak products. Outside the USA, please check with Sierra to determine if a
local authorized Sierra CalTrak service center is available.
Our elective recertification program is a complete product service package that provides pre-calibration at significant
flow points; complete product refurbishment, testing, and available upgrades; post-calibration at significant flow
points; and NIST-traceable Sierra calibration certificates backed by our accreditation to ISO 17025, ANSI Z-540, and
NIST Handbook 150 quality standards. Recertification includes a 90-day service warranty should any related labor or
parts replacements prove faulty.
Turnaround time is generally two to three weeks within Sierra’s facility from the date we received your CalTrak XL.
