Introduction
The GEO Calibration Model 1000 SP is a precision controlled humidity and temperature generator.It
provides the ability for an operator to create a precise controlled environment within a chamber for
calibrating or testing temperature and humidity sensor equipment. The unit allows the operator to
control the current temperature and humidity in the chamber from the front panel. The unit also allows
access to probe offset settings from the front panel. Advanced operations require the use of the GEO
Windows™ based application.
Operational Features
Temperature and Humidity Control
The GEO Calibration 1000 SP allows the user to generate a stable environment within its chamber. The
unit can control and maintain the relative humidity and temperature in the chamber to within a
resolution of 0.1% RH and 0.1°C respectively. The system accuracy is controlled via a NIST traceable
internal probe.
Condensation prevention
The GEO Calibration 1000 SP control system has a condensation prevention feature which will not allow
a rapid temperature drop when that drop will cause the internal chamber conditions to reach or come
close to the current dew point. In such cases the unit will slow or halt the temperature drop while the
excess humidity can be removed from the chamber. In such cases the temperature response time will be
larger but the user will not experience condensation which is a significant cause of probe error.

9
Front Panel Operation
Main screen
During normal operation the unit’s LCD screen shows the main menu which looks as below:
Figure 1 Main menu
This screen indicates the current set point temperature and humidity and the current actual
temperature and humidity inside the chamber. From this screen the user can change the set point.
The screen is organized as a grid. The grid has rows T and Hwhich stand for Temperature and Relative
Humidity and columns Set and Act representing the current set point and actual chamber for both
temperature and humidity.
The DP value is the current Dew Point temperature within the chamber based on the actual
temperature and humidity in the chamber.

10
Button Operation
The unit has 4 push buttons located below the LCD screen. The push buttons are labeled, ‘NEXT’, ‘UP,
‘DOWN’ and ‘EXIT’.
Figure 2 Pushbuttons
The ‘NEXT’ button advances the cursor to either the next user editable value or to the next menu.
Depressing the button briefly activates a field into editing mode so that it may be modified. When a field
is in edit mode it will flash. To edit the next field on the screen depressing the ‘NEXT’ button again and
the next field will flash indicating it is in edit mode. To exit edit mode either press the ‘EXIT’ button or
wait 30 seconds and the field will automatically exit edit mode.
Holding the ‘NEXT button depressed for more than 3 seconds will advance to the next menu.
The ‘UP’ button is active when a field is placed in edit mode. Pressing the ‘UP’ button increases the value
of the field while pressing the ‘DOWN’ button decreases the value. Holding either the ‘UP’ or ‘DOWN’
button for more than one second will advance the value of the field at a high rate allowing the user to
quickly change a field’s value.
Depressing the ‘EXIT’ button will exit the editing mode. Depressing the ‘EXIT’ button for 3 seconds will
advance to the previous menu.
Exit warming mode
The ‘EXIT’ button has one additional use when the GEO Calibration 1000 SP is first started it may not
have sufficient water vapor to allow the setting of higher relative humidity values. In this case the front
panel will flash the word ‘WARMING’. During this time the unit will NOT control the chamber’s
temperature or humidity. To bypass this warm up time and go directly to controlling the chamber press
the ‘EXIT’ button on the main screen. The word ‘WARMING’ will cease flashing and the unit will begin
controlling the chamber.

11
Status Lights
The four status lights located to the right of the LCD screen indicate the following. The ‘STATUS’ light
indicates the unit is active. The ‘COMM’ light indicates the unit is receiving commands from the GEO
1000 SP Windows application. The ‘LOCAL’ light indicates that the unit’s environmental condition is
being modified locally from the front panel. That is the current chamber environment has overridden
the setting made by the GEO-DFB application. The ‘FAULT’ light indicates that the BIT (Built in Test) has
detected a condition which will not allow control of the chamber. See appendix Error code for the
possible fault conditions.
Setting the current temperature and humidity
From the Main Screen press the ‘NEXT’ Button. The current set point temperature will flash indicated by
the color red in the figure below
Figure 3 Changing Temperature
Pressing the UP and DOWN button’s will change the current set temperature. The unit will immediately
begin controlling the chamber temperature to the set value. To set the humidity press ‘NEXT’ again and
the relative humidity value will begin to flash indicated by the color red in the figure below.
Figure 4 Changing Relative Humidity

12
Internal Probe Calibration Configuration
The probe calibration screen allows the user to introduce a calibration offset to the internal probe used
to control the GEO Calibration 1000 SP chamber. This allows the user to calibrate the internal probe to
an external reference.
Figure 5 Control Probe Calibration
In the image above the current probe offset is 0.1° C and the offset is -0.1% RH. The current chamber
temperature and humidity are displayed for reference. Once the offsets are configured the values are
permanently stored in the unit and do not need to be reset when the unit is subsequently powered on.
Built in Test Heat Exchanger configuration
The GEO Calibration 1000 SP Heat exchanger removes the heat generated when the peltier element is
cooling the chamber. To prevent damage the unit monitors the temperature of the heat exchanger and
will stop control if the temperature exceeds a configurable threshold. It is not recommended to change
these values as they are pre-configured for the optimal operation of the unit. The thresholds are
nevertheless configurable as shown in the figure below.
Figure 6 BIT Heat exchanger configuration
The screen displays the current temperature of the heat exchanger 15°C in the example above. The
maximum and minimum allowed temperature are configured along with whether the control should be
halted if the chamber conditions are exceeded. In addition the temperature threshold at which the
chassis fan should start is configurable. Note: the unit may override the settings depending on the exact
model.

13
Built in Test Humidity Generator configuration
The GEO Calibration 1000 SP has an internal humidity generator. This humidity generator is used as the
source to the humidity within the chamber. To ensure that there is sufficient humidity generation
capacity the unit humidity generator is kept in a warm standby state. To prevent damage from such
conditions as insufficient water the generator temperature is not allowed to exceed a certain maximum
threshold. This screen configures these thresholds. It is not recommended to change these values as
they are pre-configured for the optimal operation of the unit. The thresholds are nevertheless
configurable as shown in the figure below.
Figure 7 BIT Humidity generator
The screen displays the current temperature of the humidity generator module. The current set
temperature and the maximum allowed temperature are configurable. Whether the unit stops control
when the maximum temperature is exceeded is also configurable.
Error List
In the unlikely event that an error was detected during operation of the unit the error code and
description will be displayed on the Error list screen. A list of the possible error codes is located here

may perform initial configuration of the GEO-1000 SP, and manage the experiments database.
In bottom area of the right hand portion of the screen in the area labeled Activity Log is a textual
representation of the current activity of the GEO software and informational messages.
Experiments
The GEO software allows the user to create experiments. An experiment is defined by a sequence of one
or more phases each of which independently control the chamber conditions. The user may define any
number of experiments and each may have any number of phases. Each experiment has a Title which is
the displayed name of the experiment. Each experiment may be logged to a Comma Separated Values
file (CSV) which Is compatible with excel and numerous other 3rd party data analysis tools. The logging is
optional and the rate at which logging is to be done is configurable by the user. The experiment may
also be configured to loop forever which will cause the experiment to repeat once the final phase has
completed.
