CONNECTING TO A BALANCE
This step is not absolutely necessary. The weight (mass) of the sample can be transferred manually from the balance
to the CAL3K-A and entered on the keyboard. The balance connection cable is included in the kit. If the unit is
installed near the balance then connect up. The default balance speed is 2400baud. Set your balance to this speed!
The balance speed can be changed from the PC only. Test the connection by pressing (F5). Then the stable balance
weight should show on the display. If you press (Enter) then the mass is locked. See MASS ENTRY to unlock it.
PERFORM THE FIRST SAMPLE
The object of this exercise is to check that everything functions. We assume that the CAL3K-A and the Vessel
hardware has been tested and found to be OK.
The sample test requires the following:
The default setup (set by the factory)
One Benzoic Acid (CAL2K-4-BA) tablet, supplied in 3K-1 Installation kit
Firing cotton (3K-5-FC), supplied in 3K-5 Installation Kit
Firing wire (3K-5-FW), (already fitted to vessel lid assembly, also supplied in 3K-5 Installation kit), check that
this is present
Minimum fuss, Minimum explanations, Minimum keyboard enter
Herewith the operating sequence:
1. Weigh a Benzoic Acid (supplied) on a scale to 4 decimal places with the tarred crucible. Do not touch the
tablet but use the supplied tweezers.
2. Prepare a vessel: Attach Firing cotton thread to the Firing wire. Insert the crucible with the BA tablet in to
the holder, and position the tabled on top of the cotton thread. Handle the lid gently because if the tabled
moves and does not touch the cotton thread it is unlikely that the tabled fires. Then gently close the vessel.
Do not over tighten.
