## LIMS and Printing

The following information applies to the : CAL3K-AP , CAL3K-U , CAL3K-A, CAL3K-F All units in the CAL3K range are equipped with a powerful output (Data#1) which is useful to connect to a LIMS computer or to a printer. This output is â€˜unsolicitedâ€™ which means that no action from the …

## Zero The Pressure Transducer

The following information applies to the : CAL3K-AP The pressure transducer which monitors the vessel pressure for Filling and oxygen leakage needs to be offset adjusted so that it reads ZERO at atmospheric pressure. Although a pressure offset of 0.2 bar makes no difference to the CV determination, it can …

## User Test

The CAL3K_AP has a built in USER test which should be exercised once a day or after every power up. The test performs the indicated steps and the operator is asked to participate as indicated below. Each test step is displayed and HELP is available on every step. See: HELP …

## Unit of Measure

The following information applies to the : CAL3K-AP , CAL3K-A , CAL3K-U, CAL3K-F. The CAL3K works in MJ/Kg=KJ/g. All its internal calculations are performed in Kj/g. However, the display units and the exported CV units can be changed to CAL or BTU as follows: HOME START OF COMMAND, UNIT OF …

## Sulphur Correction

The following information applies to the : CAL3K-AP , CAL3K-A , CAL3K-U, CAL3K-F. The sulphur correction is required if the sample contains sulphur. In the presence of high pressure oxygen some of the sulphur will be converted to SO2 and some heat will be released in the conversion process. This …

## Start a Calibration

The following information applies to the : CAL3K-AP , CAL3K-A, CAL3K-U, CAL3K-F. The calibration of the CAL3K is a process in which a substance (Benzoic Acid, BA) of known calorific value is burned so that future burning of unknown substances can be compared to it. In other words the calibration …

## Spiking Operations

The following information applies to the : CAL3K-AP , CAL3K-A , CAL3K-U, CAL3K-F. The spiking method is called for when a sample has a very low CV or burns reluctantly. Then a better burning material is added to the sample to help the process. The better burning sample is the …
