1.0 INTRODUCTION 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.
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.
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.
) 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.

3) Remove the shipping protection screw and transit disc from the top of the balance. 4) Place the Chamber Support assembly onto the top housing. 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) Place the liquid chamber onto the support. Ensure the line marking the water level is to the front. 6) Place the temperature sensor onto the rear panel of the chamber. Pull the Temperature Sensor cable through the clip to take up any slack or loose amount of cable.
7) Position the sample pan in the beaker area and connect the 4 suspension wires to the rings in the support frame. 8) Plug the Temperature sensor into the 5 pin connector, and the remote Indicator into the 6 pin connector at the rear of the balance. 9) 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.
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.
2.4 KEYPAD / DISPLAY FUNCTION The keypad and display have a number of features as shown and explained below: KEYS PRIMARY FUNCTION To turn the balance On or Off. SECONDARY FUNCTION ---- [On/Off] [Tare] Tares the balance and shows the net weight value. Pressing the [Tare] again will reset another tare value [Hold/Print] Will set the current weight to be held on the display and will also send the current weight data to the RS232 interface.
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 considerably.
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.
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.
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.
table below), the karat value and content value will not be displayed. An error message will be shown. Only the density value will be available. To return to normal weighing press the [Unit/Clr] key. To run another test ensure all weight is removed from the pan support in the water and from the Density Chamber. Gold Density values used for Karat determination for silver and copper alloys.
6.0 DENSITY PARAMETERS To use the density function it is necessary to set parameters describing the liquid used and the alloy being tested. These parameters can be set when the balance is in the normal weighing mode. 6.1 SELECTING THE ALLOY TO TEST The HCB J allows the alloy to be tested to be selected by the user. Select either Gold (Au), Platinum (Pt), Silver (Ag) or disable the alloy selection and show the weight only.
temperature of the water, selections are either using the automatic temperature sensor or to manually input the temperature. If another liquid is used then the user must set the density of that liquid. The display will show Liquid, Press [Tare] to enter this section. Press [Air/Liquid] or [Density] to select H2O or Define den. Press [Tare] to select the setting or press [Unit/Clr] to return to the Liquid display.
options are Silver (Ag), Copper (Cu), Silver: Copper in a 1:1 ratio (AG:CU 1-1), Silver: Copper in a user settable ratio (Ag:Cu: M-N) or a user defined density (Define den). When the display shows Alloy, press the [Tare] key to enter this section. The display will show the current setting for the alloy as above. Press the [air/Liquid] or [Density] key to change the display to another setting, then press [Tare] to select the setting.
When the sample is Platinum mixed with an alloy the user needs to select the option that describes the alloy used.
