These nuts should be rotated upwards again to protect the load cells if the mixer is to be
shipped to another location.
Operation:
The weighing system will be powered on and start measuring as soon as the main isolating
switch is set to on.
The system is designed to measure over a 60 kg range to an accuracy of 20 g. It is supplied
already setup and configured for use with the 50 L tote, no further setup is required.
If the display is not already at 0.00, press the zero key, labelled ‘>0<’ to zero the display.
The display should always read 0.00 if the tote is empty.
Once the bag system is fully installed and the solids/liquids to be weighed are ready to be added
press the green tare key on the weigh platform display, labelled ‘>T<’.
This will remove the weight of the bag from the display and the weight of any liquids or solids
added after this point will be displayed. Likewise if the user wishes to only weigh a proportion of
the compounds being added, pressing the tare key again just before that addition will allow this
setting the display back to zero.
The tare button can be pressed multiple times, each time removing the last added weight from
the display in readiness for the next to be added and measured.
NOTE: The display also shows the word ‘net’ to indicate that only the bag contents are being
weighed.
To cancel the net weight measurement press the button labelled ‘C’. This will return the display
to measurement of the entire contents of the tote and show ‘B/G’ instead of ‘Net’ to indicate
gross measurement.
NOTE: In order to zero the display using the zero or tare button the display must be stable and
not fluctuating.
For information on calibration please contact Pall for further guidance.
