PRODUCT OVERVIEW
Calibrator Applications
Once you have removed the Model 2000 SP from its external packaging, please visually inspect
the unit for damage. If damage is found, please immediately contact your supplier.
The GEO Model 2000 SP Humidity Calibrator generates and maintains a controlled humidity and
temperature environment for the purpose of testing or calibrating humidity and temperature
sensors, also known as hygrometers. The humidity calibration range is 5% up to 95%, while the
temperature range is from 5°C to 55°C.
The system’s accuracy is achieved via a NIST traceable internal control and reference probe.
The Model 2000 SP can calibrate many hygrometer types, including but not limited to:
• Probes
• Data-loggers
• Chart Recorders
• Additional Assorted Hygrometers
Before purchasing a Model 2000 SP, please review the dimensions of the calibration chamber to
ensure compatibility with the size requirements of any Hygrometers you intend to calibrate.

Button Operation
The unit has 4 push buttons located below the LCD screen. The push buttons are labeled,
‘NEXT’, ‘UP, ‘DOWN’ and ‘EXIT’.
The ‘EXIT’ button has one additional use when the Model 2000 SP is rst started it may not
have sucient water vapor to allow the setting of higher relative humidity values. In this case
the front panel will ash 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 ashing
and the unit will begin controlling the chamber.
The ‘NEXT’ button advances the cursor to either the next user editable value or to the next
menu. Depressing the button briey activates a eld into editing mode so that it may be
modied. When a eld is in edit mode it will ash. To edit the next eld on the screen
depressing the ‘NEXT’ button again and the next eld will ash indicating it is in edit mode. To
exit edit mode either press the ‘EXIT’ button or wait 30 seconds and the eld 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 eld is placed in edit mode. Pressing the ‘UP’ button increases
the value of the eld 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 eld at a high rate
allowing the user to quickly change a eld’s value.
Depressing the ‘EXIT’ button will exit the editing mode. Depressing the ‘EXIT’ button for 3
seconds will advance to the previous menu.

Status Lights The four status lights located to the right of the LCD screen indicate the
following.
Entering Temperature and Humidity Set-points
From the Main Screen press the ‘NEXT’ Button. The current set point temperature will ash
indicated by the color red in the gure below
The ‘STATUS’ light indicates the unit is active.
The ‘COMM’ light indicates the unit is receiving commands from the GEO
Model 2000 SP Windows application.
The ‘LOCAL’ light indicates that the unit’s environmental condition is
being modied 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.

QUICK START - CHANGING DOOR
Remove screws by turning in a counter-clockwise motion.
1.
Loosen Center Screw
In some door variations, there is a center screw that serves the
purpose of creating a tighter seal. If this screw exists, it must
also be loosened using a counter-clockwise motion before the
door can be removed.
2.
Remove the Door
The best removal method is to pull from the top of the door to
break the seal. Once the top is loose, lift and pull to full remove
the door.
3.
Unscrew the Corner Screws

Control / Reference Probe Conguration
The probe calibration screen allows the user to introduce a calibration oset to the internal
probe used to control the GEO Calibration 2000 SP chamber. This allows the user to calibrate
the internal probe to an external reference.
The GEO Calibration 2000 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 congurable threshold. It is
not recommended to change these values as they are pre-congured for the optimal operation
of the unit. The thresholds are nevertheless congurable as shown in the gure below.
In the image above the current probe oset is 0.1° C and the oset is -0.1% RH. The current
chamber temperature and humidity are displayed for reference. Once the osets are congured
the values are permanently stored in the unit and do not need to be reset when the unit is
subsequently powered on.
UNIT CONFIGURATION
BUILT IN TEST HEAD EXCHANGER CONFIG
The screen displays the current temperature of the heat exchanger 15°C in the example above.
The maximum and minimum allowed temperature are congured 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 congurable. Note: the unit may override the
settings depending on the exact model.

ERROR CODES
The Model 2000 SP displays error codes through the secondary display.
These are intended to communicate machine status to the user.
Codes and Descriptions
Error Code Description
“No Analog Detected” Internal Hardware Fault Detected
“Internal Probe Fail” Internal Hardware Fault Detected
“No Peltier Temp” Temperature probe fault. Fans will run
persistently.
“No HumGen Temp” Temperature probe failure.
“HumGen Low Limit” The temperature of the ambient environment is
too low for unit operation.
“HumGen High Limit”
The humidity generator has exceeded a high
unit. Perform maintenance check of ambient
environment and water supply.
“Peltier High Limit” The cooling sensor inside the unit is above its
limit.
“EEPROM Cfg Reset” The unit conguration settings have been reset
to factor default.
“EEPROM Cal Reset” Factory calibration data reset to default.

Select Port Size Adapter
Measure the diameter of the UUT and select the
appropriately sized silicone adapter. Unscrew the Model
2000 SP door and replace the adapter if necessary.
Ensure the door is securely fastened to the chamber.
1.
Compare Readouts
Follow the manufacturer’s recommendation for
recalibration and programming osets.
4.
Program Unit Set-points
Allow the unit to reach the programmed set-points and
settle. To best preserve desiccant, it is advised that you
begin multi-point calibrations with low humidity set-
points.
3.

REFERENCE RECALIBRATION
Overview
The Model 2000 SP functions through the use of a dual PID controller. This controller takes the
humidity and temperature values from an internal capacitance probe and further performs cal-
culations that are then used to generate the user entered humidity and temperature set points.
This sensor is factory calibrated, and upon request, additionally calibrated by an ISO 17025 ac-
credited laboratory using either a chilled mirror or two-pressure primary reference standard.
When calibrating the Model 2000 SP, the chamber must be measured at a variety of tempera-
tures and relative humidity levels. It is recommended that you measurements use a 70 % guard
band to “guard” against any measurement uncertainties. The Model 2000 SP’s humidity and
temperature osets must be changed if the control probe’s readings are found to be outside of
the allowed tolerances when compared to the reference.
Recalibration Intervals
The scope and uncertainty requirements of this calibration will vary per customer. The capaci-
tance probes that we use have an average drift of 1.0% RH per year. You should account for this
interval, as well as your laboratory’s uncertainty budget when calculating out your desired recali-
bration interval. The table below illustrates accuracy drift after 6, 12 and 24 months.
Timeframe 6 Months 12 Months 24 Months
Dri(%RH) 0.5% RH 1.0% RH 2.0% RH
Based on this information, you may wish to shorten or lengthen your calibration interval to re-
spectively increase accuracy or decrease costs.
Self Re-calibration Overview
We advise that you return your reference probe to GEO Calibration for recalibration. However,
for customers that are international or operate where policy restricts the use of international
services, self recalibration is an option.
The following supplies are needed to recalibrate the internal control/reference probe.
HW4 Calibration Software
HygroClip DI Adapter Cable HC2 Pbe/USB, 6Ft
A calibration reference with uncertainties of 0.5% RH or better.
