Note: The unit conversion is only used in communicating with the CAL3K.

We know that the KBTU/lb is not conventional, but they fit nicely in to the display format.

23 FIBRE IN FOOD % 1

This percent (of mass) entry is used to reduce the result by the percentage multiplied with the FIBRE CV
VALUE, CMD=25. This fibre adjustment is NOT used during a calibration.

24 BALANCE SPEED 0

The balance must have the same setup as the CAL3K. The setting is:

Parity

None

Stop bits

Data

8 bit

Default Speed 2400

The speed in the CAL3K can be adjusted from 1200 to 38400 baud.

25 FIBRE CV VALUE 1

The Fibre CV value is used during food analysis the default is 16.736KJ/g. Unit conversion is active.

26 AVERAGE ACCEPT. 1

The entered value should follow the following grading guide:

Value

Means

0.012

Excellent

0.024

Good

0.048

Acceptable

0.096

Poor

0.192

Bad! Calibrate

A ‘ZERO’ entry (Default) disables the acceptance check.

DELETE CAL ABOVE

The is a test command. It deletes calibrations above the set limit.

28 GELATINE CAPSULE 0

A YES/NO entry enables/disables the use of gelatine capsule temperature deduction.

Note that the ‘

GELATINE CAPSULE

’ enable setting is retained after each sample. If a sample without a

capsule is burned then the capsule compensation must be disabled (CMD=28, NO)

In the ‘EASY SPIKE’ method the Capsule Rise value (CMD=29) is deducted from the measured

temperature rise ( Capsule) before the result is calculated.
