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
“two-pressure” 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

Model 2900 System Manual – Document #OM2900 - Edition 1.6 22 March 2019
9
the 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.

When not using the pneumatic cart, a clean, oil free instrument air supply operating at a @ 165 psiG and 50
L/m is required. The air supply should be filtered to a particle size of 0.5 microns or less, a hydrocarbon
content of 1 PPM or less, with a pressure dewpoint of 15 °C or less. Regulated supply pressure other than
recommended (175 psiG maximum) is acceptable but may limit the lowest humidity obtainable from the
generator and will require an internal pressure regulator (REG) adjustment.
Refer to section 2.12.5 Setting Supply Pressure Regulator for more information on adjusting the internal
pressure regulator (REG).
2.11.5
Distilled Water Supply
One gallon (3.8 liters) of double distilled water per fill. The one-gallon supply can last from 8 hours to more
than 500 hours of use depending upon the temperature and humidity at which the generator is operated
(reference section 13.3.4). During operation near ambient temperature and 50% RH, one gallon should last

visible damage that might have occurred during shipment.
CAUTION!
ALWAYS PROPERLY SHUTDOWN THE TOUCH PANEL PC VIA WINDOWS
BEFORE SWITCHING OFF MAIN POWER.
2.12.3
Chamber Fluid
Temperature conditioning of the Model 2900 test chamber utilizes a mixture of propylene glycol and water
as a heat transfer fluid. This fluid is circulated by a magnetically coupled centrifugal pump through the
refrigeration and heating system and the fluid shell surrounding the test chamber.
2.12.3.1
Chamber Fluid Filling Procedure
1. Ensure main power switch is OFF.
2. Remove top console panel.
3. Locate fluid fill port (under insulation and labeled "Fluid Fill Port").
4. Remove "Red" cap and insert funnel into fluid fill port.
5. Add 2 gallons of 70% propylene glycol. Fill with water until level is approximately 1" (25.4 mm)
below the bottom of the fill port or until level touches funnel nozzle tip.

Model 2900 System Manual – Document #OM2900 - Edition 1.6 22 March 2019

6. Remove funnel and replace fluid fill port cap and insulation.
7. Replace top console panel.
Refer to drawings: 18D29901-1, 18D29901-4, 18D29909-1
2.12.3.2
Chamber Fluid Draining Procedure
1. Ensure main power switch is OFF.
2. Remove rear console panel.
3. Locate drain hose in the lower left rear corner of the generator (when looking at the back of the
generator).
4. Extend hose, remove drain hose cap and empty the chamber fluid into a clean container with a
minimum size of 4 gallons. Save the chamber fluid for refilling.
5. To restore hose: grasp hose and rotate counter clockwise ½ turn while pushing hose into left
side storage cavity.
6. Replace rear console panel
Refer to drawings: 18D29901-1, 18D29901-3, 18D29909-2
2.12.4
Reservoir Initial Filling Procedure
The reservoir requires an initial filling prior to first use, then periodic filling thereafter.
Refer to section 5.1 Water Reservoir Level for detailed instruction on how to fill the reservoir.
2.12.5
Setting Supply Pressure Regulator
The supply pressure must be regulated to assure proper control and operation. The goal of the regulation is
to remove the spikes that occur during air supply generation.
Note –It is always recommended to double regulate the air supply; once at the supply and again at
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 (limited to 150). 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
counter-clockwise to decrease pressure while monitoring the supply pressure dialog window.
Refer to drawings: 18D29901-1, 18D29901-3, 18D29901-8
