Core Modules 13
NOTICE - Reduced lifetime!
If Calorimetry Process Control Units and Air Pumps are powered ON while there is a leakage
in the sample line, this may reduce lifetime of devices.
• Never remove collection vessels from the 4x Air Drying Unit. Drain off condensed water via
collection vessel tubing only.
• After you have discarded condensed water of separating bottle, carefully reconnect bottle to
tubing.
• Select "Status/Calo" and check for proper "SampleFlow” on "Calo Current Values" dialog (see
Software Operating Instructions - Calorimetry, Section "Status Menu, Calo").
• The test area should be limited by a door or similar so no rapid alteration in the CO2/O2
concentration of the reference air can take place during the measurement.
• A warmed-up calorimetry system should be used for an experiment only. The warming-up
period should be at least 2 hours.
• Exactly specified gases with a test certificate should be used for calorimetric calibration only.
Calibration gases (O2, CO2) which concentration is known accurately to two decimal places
should be available.
• The calorimetry sensors should be calibrated under the same conditions that are to be used
for the measurement (e.g. room temperature, pressure, location).
• The calorimetry devices of the system should be leak-free, as otherwise the measurements
will be inaccurate.
• The setting of the flowmeter (Calorimetry Master Control Unit) for the measurement should be
the same as for the calibration process.
• For better comparability of test data, the room conditions, particularly temperature and
humidity, should be kept as constant as possible.
• Air pumps (push principle respirometry, overpressure principle)
o The pump is designed for pumping air only. The performance values can be found on
the pump label.
o Ensure that the operating air temperature is within the range -10...+40°C (14…104°F)
o Ensure that humidity is <90%.
• Vacuum pumps (pull principle respirometry, underpressure principle)
o The pump is suitable exclusively for air and NOT for pumping liquids or gases. Max.
permissible humidity <90%.
o The ambient temperature must not fall below -5°C (23°F) and must not exceed +40°C
(104°F). You are NOT allowed to operate the pump close to explosive liquids or on
potentially explosive premises.
o Unusual noises may indicate that a diaphragm has broken. In this case, unplug device
from mains supply and contact TSE Service
.
• When the High-Speed Sensor Unit is in operating mode, ensure that the Oxymat sensor is
supplied with reference air (scavenging air) to protect the device against contamination.
NOTICE - Reduced lifetime!
If High-Speed Sensor Unit is powered ON without operating the system, contamination may
damage the sensors.
• During operating mode of High-Speed Sensor Unit, ensure that…
o …its sensors are supplied with air from reference gas cylinder continuously.
o …all other devices of the CaloSys module entered operating mode as well.
o …PhenoMaster software is running.
• Power OFF High-Speed Sensor Unit after use.
