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 cau

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

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 c

2.5 REAR PANEL The rear panel has connectors for the power, RS232, remote display and temperature sensor. For connections to these see the relevant sections. 2.6 INTERNAL RECHARGEABLE BATTERY The balance can be operated from the internal rechargeable battery or using an adapter. The battery life is approximately 24 hours with the backlight off. Depending on the usage of the backlight the lifetime of the battery will reduce and using the remote display will lessen the battery life con

3.0 LOCATING AND PROTECTING YOUR BALANCE In order to keep your balance functioning at its best we suggest that you do the following: Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents. Make sure the balance is located on a strong table and free from vibration. Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors. Do not let the balance battery go flat. If you are not usin

4.0 BASIC OPERATION 4.1 TURNING ON THE BALANCE Plug in the unit using the adapter or use the internal rechargeable battery. It is recommended that you charge the battery for at least 8 hours before first use. 1) To turn on press the [On/Off] key once and release. The balance will show the software revision and the battery voltage then self-test before showing the current temperature as measured or defined by the user. The balance will show the stable sign and zero weight on the disp

5.0 DENSITY FUNCTION Once the HCB J is prepared for a density test and the parameters have been set for doing the Density Determination (see section 6) the following procedure is used to weigh the sample in air, and then again in water or another liquid, allowing you to determine the density of the sample and if applicable a determination of the purity (karat) of the gold in the sample. The Hold function must be enabled (see section 7.2) for the Density function to operate correctly.

display will show “HOLD”. If the Hold function is set to automatic you are not required to press the [Hold/Print] key once the weighing in liquid becomes stable. After the Hold symbol is shown press the [Air/Liquid] key to store this value. The Weight in Liquid indicator will be shown at which point the sample can be removed. If when weighing in air the weighing unit starts to flash a message of “ADD”, this informs you that the weight of the sample may not be enough to give accurate calc
