17.2 Tare Command
Pressing the tare button will zero the balance by sending a tare command to the balance. The
balance status will display ‘Tare started…’ then ‘Tare complete’, for about 2 seconds before
displaying ‘Ready’ again. The weight reading should read zero grams.
17.3 Calibrate
To calibrate the balance a 5 kg calibration mass is required. The balance must be calibrated
after installation and if the equipment is moved it is also good working practice to check
calibration periodically. This should be done with the chamber at room temperature and with the
afterburner fan switched off. To start the calibration process, place the calibration plate (Fig:
2.2.8) onto the balance extension press the calibrate button. The status message sequence for
normal operation is:
Clear pan then press Next
Load 5kg then press Next
Calibration Complete
After pressing the calibration button the
‘Next’ and ‘Cancel’ buttons appear. ‘Cancel’ can be
pressed at any time to abort the operation. These buttons can be seen in Screen view 17.3.1
NOTE: when loading 5 kg the weight reading will remain at zero, this is normal. After the
calibration is complete the balance weight will read 5000g, until the weight is removed.
NOTE: After calibration, remove the calibration plate. This will result in a negative weight value
showing in the display. Restart the furnace using the main power switch in order to clear this
value and commence normal operation.
