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 sucient 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 briey activates a eld into editing mode so that it may be
modied. 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

Figure 5 Control Probe Calibration
Figure 6 BIT Heat exchanger conguration
Control / Reference Probe Conguration
The probe calibration screen allows the user to introduce a calibration oset 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 congurable threshold. It is
not recommended to change these values as they are pre-congured for the optimal operation
of the unit. The thresholds are nevertheless congurable as shown in the gure below.
In the image above the current probe oset is 0.1° C and the oset is -0.1% RH. The current
chamber temperature and humidity are displayed for reference. Once the osets are congured
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 congured 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 congurable. Note: the unit may override the
settings depending on the exact model.

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 calculations 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 accredited 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 temperatures 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 osets 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 capacitance 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 recalibration 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 respectively 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.
Control Probe / Reference Sensor

REFERENCE RECALIBRATION
Self Recalibration Procedure
To read the recalibration procedure of the control / reference probe, please refer to the unit’s
user manual, and the HW4 software manual found at the following URLs:
https://s.campbellsci.com/documents/ca/manuals/hc2-s3-l_man.pdf
https://goo.gl/n7qE1G
Before recalibration of any control probe, ensure that the unit and probe have both completely
settled at 23ºC for at least ten minutes.
Maintaining Probe Accuracy
The following text is the recommended maintanence best practices from Rotronic.
“The HC2S3 probe requires minimal maintenance, but dust, debris, and salts on the lter cap will
degrade sensor performance. Check the white lter on the end of the sensor for debris. If dirt or
salt is engrained into the lter, it should be cleaned with distilled water or replaced. Make sure
the lter is connected rmly with your ngers — do not over tighten.
Check the radiation shield monthly to make sure it is free from dust and debris. To clean the
shield, remove the sensor from the shield. Dismount the shield. Brush all loose dirt o. If more
eort is needed, use warm, soapy water and a soft cloth or brush to thoroughly clean the shield.
Allow the shield to dry before remounting.
Replace corroded, discoloured or clogged lters. To replace the lter, unscrew the lter from the
probe and pull it straight away, being careful not to bend or damage the sensors. Before putting
on the replacement lter, check the alignment of the sensors with the probe, and if necessary,
carefully correct the alignment before installing the lter.
The Teon lter is recommended when the sensor is installed in close proximity to the ocean or
other bodies of salt water. A coating of salt (mostly NaCl) may build up on the radiation shield,
sensor, lter and even the sensors. A build-up of salt on the lter or sensors will delay or destroy
the response to atmospheric humidity.
Long term exposure of the relative humidity sensor to certain chemicals and gases may affect the characteristics of the sensor and shorten its life. The resistance of the sensor depends
strongly on the temperature and humidity conditions and the length of the pollutant inuence.”

MAINTENANCE GUIDE
Overview
The Model 2000 SP ships with a fresh desiccant canister. Each time the Model 2000 SP dries the
internal volume of air, the desiccant will become more saturated with water. For optimal performance, the user must periodically replenish or replace the used desiccant. The desiccant type is
molecular sieve, which may be regenerated by the user through heating.
The user must replace the desiccant as soon as they see drying performance begin to degrade.
To aid in this process, the Model 2000 SP has an on-screen indicator that displays once sub par
drying performance is detected. In addition to the on-screen indicator, the desiccant itself also
contains a chemical that changes color from blue to pink when saturated with water. The user
should change the desiccant once approximately 75% of the molecular sieve has changed in
color from blue to pink.
Desiccant Change Procedure
We advise that you purchase extra replacement desiccant canisters directly from GEO Calibration. It is possible to purchase the desiccant in bulk, disassemble the canister and replace the
used desiccant with unused desiccant, however, this procedure requires the user to carefully
re-assemble the desiccant canister. If this re-assembly is done incorrectly, then air leaks may
occur and the unit performance may suer.
For visual instructions on how to perform a rell of a desiccant canister, please see the next
page.
Additional instructions can also be found on the website of the desiccant supplier.
