Thank you for purchasing your new HCB J Precious Metals and Density Balance. As
with our popular HighlandTM series of balances the HCB J has all the features you
really need: DC adapter with internal rechargeable battery, HandiCalTM calibration,
backlit display, and ShockProtectTM with overload indicator. With the RS-232
interface for communication with printers and computers, splash-proof keypad, and
sturdy plastic construction, the HCB J will be a balance you can rely upon. We hope
that you enjoy using your new balance.

SETTING UP YOUR BALANCE
1)Remove the balance and all accessories from the packaging
2) Remove the shipping protection screw and transit disc from the top of the
balance
3) Place the Beaker Support assembly onto the top housing with the
Temperature Sensor cable running down the back of the balance.
4) Lift the beaker away to the rear and locate the Density Chamber support into
the receptacle with the arrow facing the rear of the balance. Press gently to
insert it then secure the support in the center using the M4 x 20mm screw
which is packed in the accessory bag. Tighten only enough to secure the pan
support so that it does not rock in the receptacle.
5) Replace the beaker onto the beaker support and pull the Temperature Sensor
cable through the clip to take up any slack or loose amount of cable.
6) Place the Density Chamber over the beaker with the handle of the lid at the
front and allowing for the sample pan to hang freely inside it. Secure the
Chamber to the support by rotating it gently clockwise and locking into the 3
tabs. Take care not to push down or use excessive force on the Chamber
when fixing as damage can be caused.
7) Plug the Temperature sensor into the 5 pin connector, and the remote
Indicator into the 6 pin connector at the rear of the balance.
8) Make sure again that the cable from the Temperature Sensor is tightly pulled
down through the clip and that it does not interfere or sit close to the Density
Chamber or Chamber support. If the cable is touching against any of these
parts it will result in incorrect weighing and karat calculations.
Position the balance and Remote Indicator in a convenient place and adjust the
feet to show a level state.
Switch on the balance whilst using battery power or connect the adaptor to the
mains supply.

2.3 PREPARING
FOR USE
Position the balance and Remote Indicator in a convenient place and adjust the
feet to show a level state.
Switch on the balance whilst using battery power or connect the adaptor to the
mains supply.
When you are preparing to do a Density Test it will be necessary to fill the
chamber with liquid. The choice of the type of liquid will be left for the user to
decide, however some solvents may not be compatible with the Polycarbonate of
the chamber or ABS of the Sample Pan. Test a small sample of the liquid on the
plastics before filling the beaker if unsure.
Fill the chamber with liquid lift the Chamber lid, or remove the Density Chamber
from its support and pour through a funneled container. The beaker should be
filled no higher than the maximum filling mark and needs to cover the metal part
of the Temperature Sensor cable. If the Chamber is removed refit the Chamber
once finished as described earlier. Care should be taken to not spill any liquid
onto or inside the balance as damage may occur which is not covered under the
normal warranty terms.
To fill the chamber whilst it is away from the balance it will be necessary to
remove the Temperature Sensor and clip from the chamber which then allows it
to be removed from the support. The cable will need to be pulled gently upwards
from below the Temperature Sensor clip to allow easy removal of the clip. When
re-fitting the Temperature Sensor and clip follow the previous instructions
ensuring the cable is pulled down into a tight position and lifted away from the
Chamber.
If water is used a few drops of liquid detergent may be added to the water to
improve the wetting ability and avoid trapped bubbles of air on the sample being
tested. Stir well to distribute the soap evenly.
When removing samples from the chamber use a towel to dry the samples so
the water does not splash onto the balance.
The keypad and display have a number of features as shown and explained below:
