Printing | CAL3K Features

All units have a RS232 printer port designated as D1. The baud speed can be set from the keyboard. 8 printout formats A-H are available for showing different data sets on a 80 column printer.

Print outputs can be optional filtered or selected per vessel, time, GID (Group Identification) or vessel number.

If the D1 port is connected to a PC, then bulk printouts data can be dumped to a spreadsheet.

All data are identified by a ‘Header’ which is a cryptic text line. A suitable data capturing program such as ‘TERA TERM’ can capture the keyboard-initiated data and transfer it to a spreadsheet in a name.csv format.

If enabled, the result is printed automatically after a determination.

The printing refers to a ‘paper readable’ output within 80 characters.

A ‘REAL TIME’ printout is available for Universities. This printout prints data as they are captured for further external computation.

RS232 outputs with more than 80 characters per line are called ‘DATA DUMPS’

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 records all the system variables such as temperature rise and heat loss in memory. All this data is called a calibration field. The calibrations are stored in the vessel.

To perform a standard calibration using Benzoic Acid Tablets you will need: A working oxygen bomb calorimeter system connected to a power source, A CAL3K Manual Oxygen Filing Station connected to an oxygen supply (not needed when using the CAL3K-AP Calorimeter)...

The CAL3K system uses two calibrations: Keyboard calibration, in real time, one sample, average with last ‘n’ calibrations, PC calibration, in retrospect, multiple samples. The PC calibration is called ‘IntelCal’ because of its complexity and system effectiveness.
