2 GETTING STARTED
This section will provide the user with information about the Model 2900 humidity generator, where to obtain
technical support, software license agreement, specifications, uncertainty, facility requirements and
installation. Following sections will provide further details on how to use and operate the Model 2900
generator using the ControLog software.
Note
- All pressures are absolute unless noted otherwise.
2.1 ABOUT
The Thunder Scientific Model 2900 Humidity Generator is capable of producing known humidity values using
the fundamental, NIST proven, "two-pressure" principle. The Model 2900 uses this fundamental “twopressure” principle to continuously supply a known relative humidity, dew point, frost point, parts per
million, or other calculated value for instrument calibration and evaluation as well as precision
environmental testing.
The Model 2900 humidity generator encompasses a high-performance stand-alone Data Acquisition
Computer that performs all functions required for humidity generation and control and a second dedicated
Human Machine Interface (HMI) computer that runs ControLog. ControLog is a software application that
fully automates the operation of the Model 2900 humidity generator and allows various device connections
through a number of different interfaces. Data from the generator and connected device or devices is
automatically retrieved and stored for viewing in either numerical or graphical format in real time or post
process. Data can be transferred off the system via a USB drive for further viewing, post processing and
printing. The ControLog software also provides the primary interface to the operator via the multi-point
touch LCD and keyboard.
Key features of the of the ControLog software are:
• ControLog stores data into individual data sheets (tab). Each data sheet contains a spreadsheet
type view that consists of a date/time stamp and the measured data items corresponding to that
date/time stamp. Data sheets consist of three similar but different types: Device Data, File Data
and Data Summary. Each type has the same spreadsheet type view and operation, but all three
have different data sources.
• Graphing is a powerful tool used to view previously recorded data or to monitor the current data in
real-time. The graph works hand in hand with the data sheets. While the generator is in operation,
data sheets store the most recent data points from the generator and or connected devices at the
desired interval. A graph can be used to create a visual picture of this stored data.
• The Auto Profiling feature is very similar to the Generate mode with the main exception that
profiling relies on a predefined list of setpoints referred to as a profile. The user configurable profile
is used as ControLog's road map during Auto Profile operation. It defines which setpoint values to
go to, at what rate to go from one setpoint to another, and how long to stay at a specific setpoint
before moving to the next setpoint.
• ControLog supports a customizable interface that works with most devices. ControLog will allow
the user to create a new device connection using the “Connection Wizard” or open previously saved
connections. The wizard will open a separate dialog window containing various steps that will guide
the user in defining the communication required to receive the desired data items from the
6
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
device. The user can create as many (up to 60) or as few data items as they see fit for any one
device. Each data item can be uniquely named and once connected will be recorded in its own data
sheet. ControLog also allows the user to save these interfaces for future use. The “Connection
Wizard” allows the user to step through the connection configuration. Using the “Next” and “Back”
buttons the user is allowed to progress through the connection configuration steps. At any time,
the user may cancel the new connection or opening of a connection by selecting the “Cancel”
button. Once the last step has been completed the “Finish” button will be available to complete
the new connection.

Note
the 2900.
Adjust the 2900’s internal pressure regulator (REG) to 10 psiG below the supply pressure, but never above
150 psiG. For example, if the supply pressure indicates 165 psiG then adjust the internal pressure regulator
to 150 psiG. If the supply pressure indicates 155 psiG then adjust the internal pressure regulator to 145 psiG
(10 psiG below). For the best results operate the generator in run mode at the default flow rate to assure
the regulator adjustment corrects for any pressure drop caused by the flow rate.
1. Open the Supply Pressure Dialog by selecting “Supply Pressure” from the Utilities Menu Tab
2. Using a #6 or #8 straight blade screwdriver, rotate stem clockwise to increase pressure and
counterclockwise to decrease pressure while monitoring the supply pressure dialog window.

3 PRINCIPLE OF OPERATION
The Model 2900 humidity generation system is based on the two-pressure principle. This process (shown
below in elemental schematic form) involves saturating air or nitrogen, with water vapor at a given
temperature and pressure. The saturated high-pressure gas flows through an expansion valve where it is
isothermally reduced to test pressure. The indications of saturation temperature, saturation pressure,
chamber temperature, and chamber pressure are then used in the determination of all hygrometric
parameters such as %RH, Dew Point, PPM, etc. Humidity generation by this system does not depend upon
measuring the amount of water vapor, but rather is dependent on the measurements of temperature and
pressure alone. The precision of the system is determined by the accuracy of the temperature and pressure
measurements, and on the constancy of them throughout.
3.1 PRE-SATURATION (T
The air stream of a two-pressure generator must be 100% saturated with water vapor at saturation
temperature on the high-pressure (saturator) side of the expansion valve. This is accomplished by first
passing the air stream through a "Pre-Saturator". The Pre-Saturator is a vertical pressure vessel presenting a
water surface to the incoming air stream and is maintained at a temperature warmer than saturation
temperature conditions. The Pre-Saturator temperature probe is used in the control of the Pre-Saturator
heaters, which when activated, are used to control this temperature offset.
3.2 EXPANSION VALVE (T
The expansion valve temperature probe is used in the control of the expansion valve heater, which when
activated, is used to warm the expansion valve body, offsetting the cooling effects due to gas expansion.
This expansion valve temperature is always maintained above the saturation temperature.

)
27
3.3 SATURATION TEMPERATURE (TS)
The saturation temperature probe is used to measure the fluid temperature at which the airstream is fully
saturated with water vapor. This is a fundamental measurement for a Two-Pressure humidity generator.
Saturation temperature is controlled directly through the Temperature setpoint.
Refer to section 2.9 Specifications
Note - The 2900 can only operate for a finite amount of time at or below 0 °
for range.
3.4 CHAMBER TEMPERATURE (TC)
The chamber temperature probe is used to measure the temperature within the test chamber. This is a
fundamental measurement for a Two-Pressure humidity generator. Chamber temperature is controlled
indirectly through the temperature setpoint.
Refer to section 2.9 Specifications
for range.
3.5 SATURATION PRESSURE (PS)
The Saturation Pressure transducer measures and controls the absolute pressure at which airstream is fully
saturated with water vapor at saturation temperature conditions. This is a fundamental measurement for a
Two-Pressure humidity generator. Saturation pressure can be controlled directly using the Saturation
Pressure setpoint or indirectly through the humidity mode setpoint.
Refer to section 2.9 Specifications
for range.
3.6 CHAMBER PRESSURE (PC)
The chamber pressure transducer is used to measure the pressure within the test chamber. This is a
fundamental measurement for a Two-Pressure humidity generator. Chamber pressure is ambient pressure
and is not controlled.
Refer to section 2.9 Specifications
for range.
3.7 HUMIDITY FORMULAS
The humidity (or water vapor content) of a gas may be expressed in a variety of ways. While some basic
understanding of humidity is helpful, thorough knowledge of the formulas and their relationships to the
2900 is not a requirement for successful operation of the generator. Refer to the HumiCalc with Uncertainty
Reference Manual for a full description of the equations used by the 2900 to generate a known humidity
and corresponding uncertainty value.

The Run Menu allows the user to run the 2900 manually in generate mode. The Run menu also allows the
user to manually shutdown the 2900.
4.1.4.2.1 Generate Mode
Selecting Generate from the run menu commands the 2900 into generate mode. Generate mode is used to
operate the system when exact humidity points or associated time intervals have not been determined,
when data must be viewed and/or verified manually before proceeding to the next humidity point, or when
more immediate control over the generated humidity is required. When in the Generate mode of
operation, the system will control at the currently entered setpoint indefinitely. Anytime a setpoint is
changed, the system immediately begins adjusting to that new value, and will control at the new point
indefinitely. Generate mode offers the flexibility to change the setpoint at any time and does not force you
into any set sequence or for any prescribed amount of time. The Generate mode also allows you to change
the humidity control mode at any time. For instance, the system may be controlling Frost Point, then you
may immediately switch to PPMv control mode.
4.1.4.2.2 Shutdown
Selecting Shutdown from the run menu commands the 2900 to shutdown. The 2900 may be shutdown
while generating. When stopped, all system functions shutdown, pressure is vented, and the idle

interval during the generate operation. If the “Set as Default” is checked, the new value will become the
default start up interval. If not checked, the new value will only affect the current session.
IMPORTANT!
STORING AND MAINTAINING DATA CAN BECOME A TIME-CONSUMING
PROCESS. THE MORE DATA THAT IS STORED IN THE DATA TAB, THE
SLOWER AND LESS RESPONSIVE THE COMPUTER MAY SEEM. FOR THIS
REASON, SOME CONSIDERATION SHOULD BE GIVEN TO THE AMOUNT OF
DATA DESIRED, THE OVERALL TIME SPAN OF THE DATA (I.E. HOURS, DAYS,
POSSIBLY WEEKS), AND ULTIMATELY THE DATA INTERVAL.
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022

58
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
4.2.1.1.1 Setpoint Tile
The Setpoint Tiles allow the user to control the operation of the humidity generator by changing the desired
setpoint that the generator will control to. The Tiles contain 5 key parts; a header with the Parameter
Name, the Actual Value, the real-time Uncertainty Value, the Setpoint Value and the Unit the values are
displayed in. Each setpoint tile has a colored bar to allow quick indication of the what the tile is displaying
and in turn what the system is controlling. Blue is for the humidity that is being generated, red is for the
temperature that the system is controlling to and green is for the flow rate the system is generating at.
4.2.1.1.1.1 Changing Setpoints
To change a setpoint, click on the setpoint tile that you would like to change. A setpoint entry box will
appear. For example, to change the Percent Relative Humidity setpoint click on the %RH setpoint tile.
Enter the new value into the Setpoint Entry box and select Ok. Notice that the Percent Relative Humidity
setpoint value updates to the new value and the actual values begin moving toward the new setpoint.
The user can also pop-up a mini version of HumiCalc to help calculate the desired setpoint by clicking the
drop-down arrow on the setpoint entry box.
For example, let’s say the user wants to calculate the lowest %RH achievable given a limited supply pressure
of only 100 psi.
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
59
Start by opening the HumiCalc pop-up using the drop-down arrow at the right of the setpoint entry box.
Next, select the known to be Saturation Pressure and enter the 100-psi supply pressure max.
60
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
Clicking the “Calculate” button will result in the calculated %RH based on the 100 psi limit being placed in

62
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
4.2.2.1 Actively Controlled Humidity
The first tile on the Control Parameters is the actively controlled humidity parameter. For instance, if
ControLog were set to control the generator on dew point, then Dew Point would be listed as the first
parameter rather than %RH.
This setpoint controls the humidity being generated.
4.2.2.2 Saturation Pressure
The Saturation Pressure is the pressure reading of the saturator pressure transducer (T2).
For more information, refer to section 3 Principle of Operation
4.2.2.3 Chamber Pressure
Chamber Pressure is the pressure reading of the chamber pressure transducer (T3).
For more information, refer to section 3 Principle of Operation
4.2.2.4 Temperature
Temperature is the temperature reading of the saturator temperature probe (RTD1) which is a direct
indication of the fluid system temperature.
This setpoint controls the fluid system temperature within the system while generating.
4.2.2.5 Saturation Temperature
Saturation Temperature is the temperature reading of the saturator temperature probe (RTD1).
For more information, refer to section 3 Principle of Operation
Note - The 2900 can only operate for a finite amount of time at or below 0 °
4.2.2.6 Chamber Temperature
Chamber Temperature is the temperature reading of the chamber temperature probe (RTD4).
For more information, refer to section 3 Principle of Operation
4.2.2.7 Mass Flow Rate
Mass Flow Rate is the mass flow reading of the flow meter (T4). This is the actual flow of the air supply
entering the Pre-Saturator and is an indication of the total flow through the system once the saturation and
chamber pressure have stabilized.
The Mass Flow Rate setpoint controls the mass flow rate of the system.
4.2.2.8 %RH
Percent Relative Humidity (%RH) is the ratio of the amount of water vapor in a given sample to the
maximum amount possible at the same temperature and pressure. %RH is calculated at the chamber
pressure and chamber temperature relative to the saturation pressure and saturation temperature. This is
the most accurate calculation of %RH at the point in the immediate vicinity of the chamber temperature
probe. Placing the chamber temperature probe at the humidity sensing point of the devices under test gives
the actual value of the relative humidity being imposed on the devices, as it is dependent on both pressure
and temperature.

Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
4.2.2.9 Frost Point
Frost Point Temperature is the temperature to which a gas must be cooled in order to just begin condensing
water vapor in the form of frost or ice, and therefore only exists at values below 0.01 °C. When operating
the system with indicated Frost Points above 0.01 °C, the values indicated are to be interpreted as Dew
Points. However, Frost Point is not the same as Dew Point for values below freezing. Frost Point is
independent of test chamber temperature.
4.2.2.10
Dew Point Temperature is the temperature to which a gas must be cooled in order to just begin condensing
water vapor in the form of dew. Generally, Dew Point exists at temperatures above freezing. In many
instances, Dew Point may actually exist at indicated values below freezing (super-cooled dew). However, it
is important to note that Dew Point is not the same as Frost Point. Dew Point is independent of test
chamber temperature.
Dew Point
4.2.2.11 PPMv
Parts per Million by Volume is a ratio of the number of molecules of water vapor to the number of
molecules of the other constituents in the gas. Once established, PPMv is pressure and temperature
insensitive, and is therefore independent of test chamber temperature and test chamber pressure.
4.2.2.12 PPMw
Parts per Million by Weight is a ratio of the weight of the water vapor in a sample to the weight of the
remaining constituents in the gas. Once established, PPMw is pressure and temperature insensitive, and is
therefore independent of test chamber temperature and test chamber pressure.
4.2.2.13 Grains/lb
Grains per pound is a ratio of the weight, in grains, of water vapor to the weight, in pounds, of the other
constituents in the gas. (7000 grains = 1 pound). Once established, Grains/lb is pressure and temperature
insensitive, and is therefore independent of test chamber temperature and test chamber pressure.
4.2.2.14 Enthalpy
Enthalpy is a measure of the amount of energy required to change a gas from one temperature/humidity
value to another. In application, enthalpy is not used as an absolute value, but rather it is the difference in
enthalpy between two distinct points which are of interest. The datum point which results in zero enthalpy
was therefore arbitrarily chosen at a test temperature of 0 °C and 0 %RH. Applying enthalpy is a matter of
computing the difference in enthalpy between two or more distinct data points.
4.2.2.15 SVP@Tt
Saturation Vapor Pressure (SVP) computed at the Test Temperature.

Absolute Humidity is the weight of the water vapor per unit volume of humidified gas.
4.2.2.23 Dry Air Density
Dry Air Density is the partial density in weight per unit volume of only the dry air portion of a moist air
sample. In other words, if the water vapor were removed from a fixed volume of air, the remaining dry air
would exhibit this density.
4.2.2.24 Moist Air Density
Moist Air Density is the total weight per unit volume of a moist air sample. This density includes both the
weight of the air and the weight of the water vapor.
4.2.2.25 Wet Bulb Temperature
Wet Bulb temperature is used in wet bulb/dry bulb aspirated Psychrometry, and is the temperature
measured by a temperature probe whose tip is coated with water (typically by being covered with a wet
sock). When aspirated at a constant air velocity, the wet bulb will cool due to evaporation of the water from
the probe. The cool temperature, to which it equilibrates, is used in the calculation of humidity parameters.
4.2.2.26 Mixing Ratio by Volume
Mixing Ratio by Volume is a ratio of the partial pressure of the water vapor to the partial pressure of the
remaining constituents in the sample. Mixing Ratio by Volume is independent of test chamber temperature.
4.2.2.27 Mixing Ratio by Weight
Mixing Ratio by Weight is a ratio of the weight of the water vapor to the weight of the remaining
constituents in the sample. Mixing Ratio by Weight is independent of test chamber temperature.
4.2.2.28 Percent by Volume

5 FLUID LEVELS
The Fluid Levels dialog allows the user to view the current level of the Water Reservoir along with the states
of the liquid level sensors.
To access the Fluid Level dialog, select Reservoir Level from the Generator Utilities menu.
For more information, refer to section 12.4 Fluid System
5.1 WATER RESERVOIR LEVEL
The Water Reservoir Level is the measured distilled water level in the water reservoir and is an indication of
the amount of distilled water available to fill the Pre-Saturator during operation. This is the distilled water
supply used by the generator to generate a humidified gas output.
78
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
5.1.1 Fill Water Reservoir
a) Remove the reservoir fill port cap located on the top panel of the system. Attach the provided
funnel to fill port.
CAUTION!
THE SYSTEM MUST BE SHUT DOWN AND VENTED OF PRESSURE
BEFORE THE WATER RESERVOIR CAN BE FILLED
b) Add up to 1 gallon (3.8 liters) of double distilled (or better) water until the Water Reservoir Level
indicates full. A small funnel may be useful. Add the water slowly so as not to overfill the reservoir.
c) Remove funnel and replace fill port cap, finger tighten, and proceed with operation.
Note
- If the water reservoir is out of water and the system shuts down with the “Unable to Fill Pre-
Saturator Reservoir” error you must refill the water reservoir to a minimum of 75% full before trying
to generate again. It is recommended to always fill the reservoir to 100% whenever filling is required.
It is possible to overfill the reservoir depending on the rate the reservoir is filled. The system will indicate an
over filled condition by displaying the tank level in red. In most cases this is not an issue but if the system is
filled over 110% there is a possibility that the pre-saturator will become over filled. It is best to drain the
pre-saturator and let it refill. Refer to section 13.1 DRAIN PRE-SATURATOR
.

79
5.2 LIQUID LEVEL SENSORS
Liquid Level Sensors indicate a discrete state of the given sensor. Red indicates no water sensed and green
indicates water is sensed. The exception is the pump water circulation Flow Switch (FS1) where red
indicates no fluid flow and green indicates the presence of fluid flow.
5.2.1 Pre-Saturator Level
The Pre-Saturator Level is a discrete indication of the Pre-Saturator water level. When the system is
shutdown, a click of the label or indicator will start a manual filling process for the Pre-Saturator. This
feature is mainly used after the water reservoir tank is filled or when the Pre-Saturator has been drained.
Note - The system will automatically fill the Pre-Saturator as needed while generating.
Click the “Pre-Saturator Level” label and the system will open the pre-saturator fill solenoid to allow distilled
water to flow from the reservoir to the Pre-Saturator. The system will indicate that it is filling with the
message “Filling Pre-Saturator” and will continue the fill process until the Pre-Saturator is full as indicated by
the Pre-Saturator Level indication turning green. Once filled the system will automatically stop and close the
pre-saturator fill solenoid. The user has the option to cancel the filling operation at any time by clicking the
label or indicator again.

5.2.2 Flow Switch
The Flow Switch (FS1) is a discrete indication of the water circulation pump operating correctly. When the
flow switch indication is red, water is not being circulated within the system. Water will only be circulated
when operating in the Generate mode.

6 CALIBRATION
Proper calibration of the temperature and pressure transducers is critical to the accuracy of the generated
humidity. Each time a probe or transducer is calibrated its current calibration coefficients and calibration
data are stored to disk. Calibration of the system requires the following support equipment:
Note - The following information is provided as a recommendation for the calibration of the Thunder
Scientific 2900 Humidity Generator. It is the user’s responsibility to ensure the standards used meet/exceed
their organization’s specific test limit/guard banding requirements.
1) Temperature, range 0 to +72 °C (standard range) or -10 to +72 °C (low temp range):
• Precision temperature bath of specified range with a liquid medium (recommend FC-77
Fluorinert, a 3M product).
Note - Less stable baths may require the use of a thermal block.
• Standard or reference thermometer (PRT) of specified range with an accuracy low
enough to assure ±0.027 °C test limit or guard band.
2) Chamber Pressure, range ambient to 17 psi absolute:
• Stable static gas pressure source.
• Standard or reference pressure gauge with an accuracy low enough to assure ±0.020 %
of reading test limit or guard band.
3) Saturation Pressure, range ambient to 160 psi absolute:
• Stable static gas pressure source.
• Standard or reference pressure gauge with an accuracy low enough to assure ±0.020 %
of full-scale (160 *± 0.020% = ±0.032 psi absolute) test limit or guard band.
5) Flow, range 0 to 50 standard liters/min:
• Reference flow meter with an accuracy low enough to assure ±5.0 % of full-scale (50.0
*± 5.0% = ±2.5 liter/min) test limit or guard band.
Note – Flow is standardized with a reference temperature of 70.0 °F at 760 torr
6.1 TEMPERATURE CALIBRATION
The temperature calibration procedure is used in conjunction with a precision temperature bath for
calibration of the temperature probes. By using the temperature bath to generate up to five known
temperatures, all coefficients will be calculated automatically by the computer and used to update the
system calibration. Calibration reports will be generated and can be saved for each of the temperature
probes at the conclusion of each calibration sequence.
Refer to drawings: 18D29901-1, 18D29901-3, 18D29901-4

6.1.2 Calibration Procedure
For safety purposes, perform a shutdown, perform a shutdown system, switch system "POWER" to OFF and
remove power cord before removing any panel or air supply line.
1. Disconnect the air supply line to generator and remove air supply inlet fitting.
2. Remove the top, left and rear panels.
3. Remove temperature probes to be calibrated:
Note
- The Cabinet Temp (RTD5) does not require calibration and can't be removed.
• Chamber Temperature Probe (RTD4): Remove the access port insulation. Using the Long Nose
Pliers, grasp the rubber cork and pull straight up. Remove the probe by feeding the cable and
probe up and through the chamber access port.
• Saturation Temperature Probe (RTD1): Remove the access port insulation. Using the “Temp
Probe Tool”, loosen the captive nut ½ turn counterclockwise (do not remove captive nut) and
remove the probe by pulling straight up from the access port fitting.
• Expansion Valve Temperature Probe (RTD3): To access to the Expansion Valve Temperature
Probe, remove the expansion valve access cover. Remove the expansion valve insulation. Using
the “Temp Probe Tool”, loosen the knurled compression nut ½ turn counterclockwise (do not
remove captive nut). Gently pull the probe straight up to remove probe.
• Presaturator Temperature Probe (RTD2): Remove the Presaturator Temperature Probe by
pulling the “Probe Captive Stay” straight down then pull the Presaturator Temperature Probe
straight down from the thermal well. Pull the cable and probe up and through the 2900 frame
corner
4. Bring a precision temperature bath with reference thermometer to the system. Pull the split tube
temperature probe covering from the frame corners to allow the temperature probes to reach the
temperature bath. Install the temperature probes into temperature bath.
5. Switch main console power ON. Wait a few moments for the system to initialize and for the
Control/Display screen to appear.

CAUTION!
DO NOT ENABLE CONTROL BY SELECTING GENERATE WITH ANY
TEMPERATURE PROBE REMOVED FROM THE SYSTEM.
From the Units menu tab select the desired temperature units for calibration. Once calibration has begun,
the units should not be changed again until the calibration is complete.
Select
Generator Calibration from the Utilities menu tab to open the Calibration Wizard.
84
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
Select, “Take “As Received” points”. This will allow the user to take points with the current calibration to
determine out of tolerance. After all “As Received” points have been taken the user will be asked whether
they want to calculate new calibration coefficients.
Set the type of calibration to Temperature.
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
85
Select the temperature probes to be calibrated. In most case this will be all four probes, but the user is able
to calibrate any given probe separately or together.
If the temperature standard is a connected device (refer to section 9 Connections
), you may select it for the
calibration. You can use a single device item with the same calibration type from any connected device.
ControLog will automatically record the standard’s value during each calibration point. If the standard is not
connected or if you desire to manually enter the standard’s value, then simply do not select an item from
the list.
86
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
Enter the Name and ID of the standard being used. This information will be populated on the calibration
report. Selecting “Next” without entering a Name will result in ControLog giving the standard a generic
name.
Enter the desired calibration tolerance or guard band for the calibration. ControLog will signal the user that
a calibration item is out of tolerance based on the value entered above.
The tolerance is the allowable variation between the standard or reference and the item being calibrated.
This is best thought of as a window based on a minimum and maximum value, the minimum being the
standard minus the tolerance and the maximum being the standard plus the tolerance. If the value of the
item being calibrated is outside the window, then the item is considered out of tolerance.
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
87
An out of tolerance condition will be indicated by a red circle with an exclamation point for the out of
tolerance probe in the Error column.
Enter the sample size used to perform the standard deviation calculation. The sample size is the given time
that ControLog will use to determine which data points to use to determine the standard deviation of each
probe.
Note
- The number of points used will be based on the data storage rate you have selected
along with the desired sample size. For example, if the data storage rate is every 30 seconds
then a sample size of 10 minutes will result in 20 points being used to calculate the standard
deviation.
88
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
Select the number of points you would like to take for this “As Received” calibration. Each point defines
what the “true” value is at a given point based on the standard or reference value. The number of points
determines the degree of the polynomial used to align or correct the generator with the standard or
reference.
Five calibration points are recommended for all temperature probes using the following temperature points:
• 0 °C, 17.5 °C, 35 °C, 52.5 °C, and 70 °C.
Note - The specific points can be different than those listed above. Use best metrology practices when
determining which the points to take.
Using the temperature bath, generate the first temperature point (0 °C). If the standard is not a connected
device, then ControLog will ask for the value before taking the point. You can also enter a standard or
reference value before taking a point by clicking the cell in the “Standard” row and “Value” column. This is
useful for seeing error values before a point is taken.
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
89
Once the readings are stable, click the “Take Point” button. Then once a point has been taken the wizard
will automatically advance to the next point.
Tip - Use the “Next” and “Back” button to navigate between taken points. You can clear and retake
a point by simply clicking the “Clear Point” button and then repeat the process to retake the point.

Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
Using the temperature bath, generate the second temperature point (17.5 °C). Once the readings are stable
enter the standards value and click the “Take Point” button.
Using the temperature bath, generate the third temperature point (35 °C). Once the readings are stable
enter the standards value and click the “Take Point” button.
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
91
Using the temperature bath, generate the fourth temperature point (52.5 °C). Once the readings are stable
enter the standards value and click the “Take Point” button.
Using the temperature bath, generate the last temperature point (70 °C). Once the readings are stable
enter the standards value and click the “Take Point” button.
92
Model 2900 System Manual – Document #OM2900 - Edition 2.0 - June 2022
When all temperature points have been entered, ControLog will advance to the “As Received” calibration
report. Each temperature probe will appear in its own tab and contains the data for each calibration point
along with the coefficients used at the time the points were taken.
Clicking the “Save Reports” button will open a file dialog to save the report. The default file location is
…Documents\Thunder Scientific\2900 ControLog\Reports\. If the report is saved in an Excel format, then
each probe will appear in its own tab within the workbook. The user needs to save in a text-based format
then a file for each probe calibrated will be created.
