Understanding the Veriteq Spectrum System
The Veriteq SP-Series system consists of one or more Veriteq SP-Series Data
Loggers, Veriteq Spectrum 4.0 software, a Veriteq cable (PC-IC cable if connecting by Serial port, INT-USB-DL cable if connecting by USB, or Digi and
Ethernet cables if connecting via Digi or Veriteq vNet device through the network), and a PC with an attached printer.
2
Veriteq Spectrum 4.0 User’s Guide
The SP-Series Data Loggers are connected to a PC and the Spectrum software
is used to configure settings such as the sampling interval. The data loggers are
then placed in the area where conditions are to be monitored and they record
the information. The data loggers collect the information and store it in their internal memory. Once the desired information is collected, it is transferred to a
PC with Spectrum. The data is imported (“inserted”) into a Spectrum graph and
Spectrum software is used to display, analyze, print graphical or tabular reports,
and export the information.
The following illustration shows how the Veriteq SP-Series system is used to
collect and report data.

Each Veriteq SP-Series Data Logger is factory-calibrated against National Institute of Standards and Technology (NIST) traceable standards. All calibration
information is stored digitally in the logger’s memory. For data logger specifications, see www.veriteq.com or contact Veriteq.
There are many models of SP-Series Data Loggers to choose from, including
the SP-1000, SP-1400, SP-1700, SP-2000, and SP-4000. Each logger has one
or more channels and can monitor and record data, including ambient temperature and relative humidity. Many loggers can also have optional plug-in external probes attached.

Ensuring Data Loggers are Calibrated
Veriteq SP-Series Data Loggers are calibrated at Veriteq Instruments and
should be calibrated on a suitable frequency as determined by the accuracy requirements of the application in which the product is used.
Veriteq Instruments recommends a 90-day interval for the most critical applications, while a one-year interval may be adequate for less demanding situations.
To calibrate your loggers, contact Veriteq Instruments for pricing, lead times,
and delivery arrangements.
Note: Treat the calibration process very carefully. The consequences of poor
calibration can be very expensive. Veriteq SP-Series Data Loggers are
high-accuracy instruments. In order to maintain the specified accuracy,
it is essential to have trained calibration personnel, strict calibration
procedures, and proper test and calibration facilities. If you have questions about the calibration process, contact Veriteq Instruments.

19
Getting Started
Logger Status
Start Time
Indicates the sampling status of the currently-connected data logger. The possible modes are:
• Sampling: The logger is currently taking samples and the memory is
not full.
• Sampling (wrapped): The logger is currently taking samples with
the memory full. The oldest reading is discarded and replaced with
the newest.
• Stopped at specified time: The logger is not sampling and has
stopped because the user-set stop time has been reached.
• Stopped when full: The logger is not sampling and has stopped
because it is configured to stop when the memory is full.
• Start at specified time: The logger is not sampling, but is set to
begin sampling as soon as the Start time is reached.
• No enabled channels: The logger is not sampling because no chan-
nels are enabled.
The Setup button to the righ t of the Lo gger Status enable s you to clear the logger’s memory and change the Sample Interval, Start Mode, and Stop Mod e
settings.
Indicates either the time that the curr ently-connected data logger began taking
samples, or the time (in the future) that it is set to begin taking readings
Future Start times are indicated by a ( ) symbol.
For information on changing the Start Time, see

see
Setting the Sample Interval on page 26.
Note: The most frequent sampling rate possible with SP-1016 and SP-1416
loggers is once per minute. For other loggers, the most frequent sampling possible is once every 10 seconds; however, sampling of this frequency will have a negative effect on battery life.
Indicates how the currently-connected data logger is set to stop while recording samples in its memory. There are three choices: Wrap when full, Stop
when full, and Stop at specified time. For more information on setting Stop
modes, see

1. Under Clear Mode, select one of the following options:
Do not clear logger
Clear Logger
This is the default setting if the logger memory is
not yet full.
Use this setting when the logger memory is not yet
full and all you want to do is change Stop mode settings without clearing the existing samples.
If the logger memory is full, or if Start mode or
Sample Interval changes are required, you must
use the Clear logger setting to make the necessary
changes.
This is the default setting if the logger memory is
full.
The Clear logger setting allows you to modify
both Start and Stop mode parameters and change
Sample Interval values. Choosing this setting results in the logger’s memory being cleared following completion of the setup changes. You will lose
data unless you transfer it first.
If you are in doubt as to whether the information on
the logger is still valuable, first make a copy of the
data using Logger>Transfer, and then make the
necessary logger setup changes.
When you choose Clear logger, the Start Mode
and Stop Mode radio buttons become available.

applied to the logger’s memory.
Start at
specified
time
This option sets a connected data logger to start taking
samples at a pre-defined date and time in the future. Until
then, the logger remains dormant. This delayed start feature helps to save logger memory and minimizes the collection of unwanted data. You can also use the Start Time
option to ensure that multiple data loggers are synchronized to start logging at the same time.
3. When you choose the Start at specified time option, the Start Time sec-
tion of the Logger Sample Timing window becomes available. Use the
Date, Hours, and Minutes drop-down lists and AM/PM radio buttons to
set the time you want the data logger to begin recording samples.
Note: You can not choose a date or time earlier than the current date and
time values.
24
You can use the Start at specified time option in conjunction with the Stop at
specified time option to create a pre-defined data logger monitoring period.
Setting the Stop Mode
The Stop Mode enables you to choose how the connected data logger operates
once the memory is full, or when a specified time is reached.
Veriteq Spectrum 4.0 User’s Guide
If desired, use the Preset button to automatically set the start time hours
and minutes to the earliest possible setting for the date selected. For any
day other than the current day, this value is 12:00AM.
25
Getting Started
To set the Stop Mode:
1. Under Stop Mode, select one of the following options:
Wrap when full
Stop when full
This is the default method of collecting samples on
the data logger. When you choose this setting, samples are recorded in a first in, first out manner. When
the memory is full, the logger continues to take samples by discarding the oldest one, and replacing it
with the newest one.
The Wrap when full setting ensures that you always
have the latest data when you transfer from the data
logger. The length of time that the memory fills and
wraps around is a function of the Sample Interval
(see Setting the Sample Interval on page 26) you have
set on the logger. Veriteq Spectrum automatically
calculates this time and displays it in the Log Time
section of the Logger Sample Timing window.
Note: If the memory wraps around too quickly, you
can choose a longer sample interval.
When you choose this method, the logger stops taking readings once the memory is full. This option allows the maximum amount of samples to be taken
without overwriting data. It is particularly important
in any application where there is an excessive time
delay between the gathering of the data and the transferring of that data to the PC.
Stop at specified
time
The Log Time drop-down lists enable you to set an elapsed time for the data
logger to collect samples. For example, you can set the data logger to collect
samples for 24 hours, 48 hours, 7 days, and so on.
The Stop Time drop-d own lists enable you to set absolute date and time values
for when the logger is to stop taking samples.
Note: The Log Time and Stop Time options are interrelated. Setting the Log
Time to a specified period automatically adjusts the Stop Time values.
Adjusting the Stop Time Date and Time values, in turn, automatically
adjusts the Log Time values.
Setting the Sample Interval
You can change the sample intervals on the logger to suit the requirements of
the application. You can set up more frequent sampling intervals to capture rapidly changing data, or spread out the readings to maximize memory and cover
extended monitoring periods.
This method enables you to set a precise time for a
logger to stop recording data. When you choose this
setting, both the Log Time and Stop Time sections
of the Logger Sample Timing window are available.
26
Veriteq Spectrum 4.0 User’s Guide
Note: You can only change sample intervals if you set the Clear Mode to the
Clear logger setting (see Setting the Clear Mode on page 22).
To change the sample interval on the currently-connected logger:
1. Select Logger>Sample Timing....
2. Under Sample Interval, use the drop-down lists to set the Days, Hours,
Minutes, and Seconds to the desired sample interval.
If you want to use a sample interval of once per minute, click the Default
button.
You can choose intervals ranging from a minimum of ten seconds to once
every 24 hours.
The total period covered by a logger before the memory is full depends on
how many channels are enabled and the sample interval. This information
is automatically calculated in the Log Time section of the Logger Sample
Timing window.
Note: Running the logger with a sample interval shorter than one minute for a
prolonged time shortens the battery life.
Enabling and Disabling Logger Channels
The Logger Channels option enables you to enable or disable the channels on
the currently-connected data logger.
Note: During this process the data logger’s memory is cleared. If the informa-
tion on the data logger is still of value, transfer the data to a PC before
enabling or disabling channels.
27
Getting Started
To enable or disable data logger channels:
1. Do one of the following:
• Select Logger>Channels...
• You can also enable or disable data logger channels by selecting Log-
ger>Setup (or pressing F11 or clicking the Logger Setup icon on the
toolbar ( )). Then, in the Logger Setup window, click the Setup... button beside the channel you want to enable or disable.
2. In the window that appears, select or deselect the checkbox to enable or disable a channel.
3. Click OK. This initiates the process of clearing the data logger’s memory.
Note:
• A channel must be enabled before it can start collecting readings.
• It is a good idea to disable unused channels to maximize logger memory.
• If you are using a temperature and humidity data logger, remember that the
humidity sensor requires temperature values. You cannot disable the temperature sensor channel if you are using the humidity channel.
Configuring Channels to Work with Transducers
This section applies only to those using Veriteq SP-4000 series data loggers.

value to show as 1, indicate 1 for Above Threshold and specify the units.
Boolean choices are typically 1 (above threshold) and 0 (below threshold).
5. Click OK.
Configuring Warm Up Time
Note: This section only applies to Veriteq SP-4000 data loggers.
Some SP-4000 data loggers have the ability to switch power from an external
battery onto a transducer using the Warmup Time feature, also known as the
XPS excitation control switch. This is useful for conserving power when an external transducer is being powered from an external battery.
Set transducer warm up time to a number of minutes or seconds before data is
recorded by the data logger. To set when the data logger will record data, see
Setting the Data Logger Sample Timing on page 22.
To configure transducer warmup time:
1. Choose Logger>Setup.
2. From the row for the channel you want to set up the warm up time for, click
Setup.
3. From the Setup Channel screen, click Warmup Time.

Mounting Data Loggers
Because they are small and light, you can easily mount Veriteq data loggers in
the field using a variety of techniques including Velcro strips, double-sided
tape, duct tape, and magnetic strips.
In harsh environments, place the data logger in a standard industrially-rated enclosure, and run external sensors and probes from the enclosure using special
fittings in the openings.
Some tips for placing the data loggers:
Ventilation: Don’t obstruct the air passage holes in the logger. There should be
a clear path for the air to get to the internal sensors (if they are used or available).
Vibration: Excessive vibration can knock the unit off its mounting. If the location is subject to excessive jarring or vibration, mount the logger more securely.
Temperature: Excessive temperature (low or high) can affect adhesives.
Moisture: Moisture can also affect the adhesive durability.
Veriteq Spectrum 4.0 User’s Guide
Permanence: Make sure the mounting location is permanent for the duration
of the recording period.
Public access: If the logger location is too visible, people may interfere with
the readings. Make sure it is not too accessible.
Using External Temperature Probes
Veriteq SP 1000, 1016, 1400, 1416, and 1700-series data loggers have external
temperature channel(s) for use with an external temperature probe. Using the
external temperature probe enables you to collect data from hard-to-get-at locations, such as in duct work or under pipe insulation.
You can use an external temperature probe with these data loggers, provided
the probe was calibrated with the data logger.
To use an external temperature probe:
1. Enable the desired channel on the logger (see Enabling and Disabling Logger Channels on page 27). If you do not need to monitor from the internal
temperature sensor, disable it to conserve memory.
Note: You can disable most unused channels - external probe or not - to
save data logger memory. One exception is the internal temperature
channel on SP-1700 data loggers.
33
Getting Started
2. Attach the temperature probe to the connector on the data logger.
3. Use the Logger>Setup window to test the data logger operation (refresh
the readings as required).
4. Place the logger in the desired location and start recording.
Caring for Relative Humidity Sensors
Each Veriteq SP-2000 data logger has a relative humidity sensor. Although the
sensor has been designed to resist contamination and condensation, avoid exposing the data logger to contaminants, if possible.
For information on specific environments, contact Veriteq Instruments.

Setting Sample Smoothing
In Spectrum, sample smoothing controls how samples in a logger file are interpreted when they are inserted into a graph, allowing you to dampen the effects
of ‘noise’ in Logger files.
Sample smoothing is the minimum change in input signal required to cause a
change in displayed channel values, and is defined in raw analog-to-digital converter counts.
Spectrum allows you to set two different sample smoothing values: one for
thermocouple channels, the other for other channel types.
Note: Sample smoothing only affects how samples are interpreted and pre-
sented in graphs and reports; the data in the loggers and the logger files
is not affected by any settings related to sample smoothing.

Troubleshooting
Serial Port Problems
If you are experiencing difficulties communicating with Veriteq data loggers,
here are some tips and things to try before calling Veriteq Instruments.
Software Error Messages you May Encounter…
Unable to allocate COM port because it is busy
This error message means that Spectrum was unable to allocate the COM port
because it was already allocated by a different program. You may have to wait
until the COM port becomes available.
Unable to allocate COM port because it is unavailable
This error message means that Spectrum was unable to allocate the COM port
because it did not exist in the operating system. Check your available COM
ports.
Unable to receive sync byte from COM port
This error message means that Spectrum sent a request message to the data logger, but did not receive any response from the data logger. This could mean the
data logger is unplugged or the cable is not connected properly.
Unable to receive all of the bytes from COM port
This error message means that Spectrum sent a request message to the data logger, but received an incomplete response message from the data logger. This
may mean there is a problem with the COM port on this PC, a problem with the
cable, or a problem with the logger itself. Check these possibilities.
Unable to communicate with logger on COM port
This error message covers miscellaneous error conditions, other than those listed previously. This message could mean that there is a problem with the COM
port on this PC, a problem with the cable, or a problem with the logger.
Things to Try:
1. Does the logger and interface cable work on a different PC? If so, the problem likely resides in the serial port configurations on the PC.
2. Are there other devices (such as a mouse) that use the serial port in question
without problems? If so, that port is likely not the problem.
3. Can you transfer data using a different interface cable? If so, the cable may
be damaged.
4. Can you transfer data using a different logger (with the same interface cable)? If so, the data logger may be damaged.
66
Invalid hardware model
This error message means that Spectrum did not recognize the hardware model
of the data logger, and as a result, did not know how to interpret the information
stored in the data logger. Ensure you are using a data logger supported by Spectrum.
Unable to create logger file
This error message is generated when Spectrum attempts to create a logger file
on a disk and an error occurs. Some possible reasons include:
• The disk is full.
• The user does not have write access to the disk. Ensure the user has write
permission to the folder where the logger file is being saved.
• The file is already open by a different program. Close it.
• The file name is invalid. Try using a more simple .spl file name.
Frequently Asked Questions
I have recently upgraded Veriteq Spectrum software to the latest version. Will
this new software work with my existing loggers and files?
Yes. Each version of Veriteq Spectrum software is designed with backward
compatibility. This means that it works with all previous versions of loggers or
files created from those loggers.
Veriteq Spectrum 4.0 User’s Guide
I have recently purchased a new logger. Will it work with my older version of
Spectrum software?
Not always. In our pursuit of continual product improvement, we periodically
upgrade logger hardware or release new logger models. Unfortunately, these
changes may not be recognized by an older version of Veriteq Spectrum software and can result in difficulties. For that reason, each logger that you purchase includes a note indicating which software version it must be used with.
The safest choice is to always upgrade to the latest version of software. Contact
Veriteq Instruments if you require a software update.
Does the software account for daylight savings time changes?
Yes. Daylight savings time changes are automatically accounted for in all graph
and tabular displays.
How many logger files can I overlay onto the same graph?
You can overlay many channels of data onto the same graph; in testing, we inserted more than 100 channels successfully.
Do all graphs have to be created from one data logger?
No. You can create graphs using files from different data loggers and different
data logger models.

Dewpoint Dewpoint is defined as the temperature at which the amount of moisture

present in the air is the MAXIMUM amount the air can hold (at a constant
pressure and water vapor content). This means that when the temperature
falls to the dew point, the relative humidity is 100% and the air is considered
saturated.
Dewpoint does not vary with temperature, as does relative humidity (RH).
Rather, dewpoint is a DIRECT measure of the actual moisture content in the
air and thus is preferred as the unit of measurement in many scientific and
industrial applications—particularly in tightly controlled environments where
precise indications of water content in the air are required.
The dewpoint is never greater than the air temperature. Once the dewpoint is
reached and the air temperature continues to drop, water vapor is forced to
leave the air through condensation. This condensation may take the form of
water droplets, dew, or may remain suspended in the air as clouds or fog.
To better understand how dewpoint and relative humidity are related to each
other, try inserting a logger file with relative humidity (RH) channel values into
a graph twice—once, displaying RH using dewpoint and once displaying RH
using relative humidity.
In Spectrum, dewpoint readings below 0 degrees C are recorded as frostpoint.
F–K
Graph file A file that is created to display the data from one or more Logger files. Graph
files retain formatting information such as graph title, zoom levels, Y-axis scaling, and Logger file data; and are identified by their .spg extension (for example, LAB_1.spg).
L–Q
Local time A value equal to the current time used at a particular location. A relative indi-
cator of time meaningful only if Time Zone Information is also known. Local
Time contrasts with UTC Time, an absolute time reference. The software
records Local Time and UTC Time in each Logger file.

Veriteq Spectrum 4.0 User’s Guide
Logger file A file that is created after transferring a logger’s data to the PC. The file con-
tains the collected readings (from all active channels) for the transferred logger, including the logger’s description, model number, serial number,
firmware version number, file description, Local time, and UTC (Universal
Time Coordinated) time. Logger files are identified by their .spl extension (for
example, PRIMARY_GAS_FLOW.spl). Logger files cannot be viewed
directly—you have to insert the Logger file into a Graph file before the data is
displayed as a graph.

R–T
Range Normal operating limits, specified by the lowest calibration point to the high-
est calibration point.
Relative humidity Relative humidity is the measure of the amount of water vapor in the air com-
pared to how much it can possibly hold at that temperat ur e. A relativ e humid ity of 50% means that the air contains only one-half as much water as it could
possibly hold. The capacity of air to hold water is heavily dependent on the
temperature of the air. The colder the air, the less wat er it can ho ld. Air at
50°F can hold only one-quarter the amount of water as air at 95°F.

Glossary
Transfer The term used when the software makes a cop y of the data contained in a
connected data logger. The transfer process creates a file on the PC but does
not affect or delete the data on the logger. Other terms commonly used to
describe the transfer process are download, upload, backup, or copy.
U–Z
USB An acronym for Universal Serial Bus, a standard for connecting external
devices such as a mouse, keyboard, scanner, printer. USB offers many benefits over serial and parallel port connections, including thinner and cheaper
cables, greater expandability (with the addition of a USB hub, a single USB
port can handle over 100 peripheral devices) and greater speed.
UTC An acronym for Universal Time Coordinated, UTC is a standard time com-
mon to every place in the world. Also known as Greenwich Mean Time (GMT)
and World Time. UTC is expressed using a 24-hour clock but can be converted into a 12-hour clock (AM and PM). An absolute time reference that
does not rely on Time Zone information, UTC contrasts with Local time. UTC
and Local Time information is contained in Logger files and is used to form
the time base on logger graphs and data.
