This same procedure should also be followed when battery replacement becomes necessary. Make certain that only “C” size alkaline batteries are used as replacements. NOTE! Exposure of batteries to high temperatures (above 140° F) will decrease their capacity resulting in shorter operation time. Step 1 Using a screwdriver, remove the two retaining screws from the back of the instrument. Remove the battery compartment cover. Battery Compartment Cover Remove these screws Step 2 Remove the old batteries, if present. Insert six new “C” cells making certain that each cell is correctly positioned. Refer to the next diagram for proper battery placement. 2 BATTERY INSTALLATION, Cont. Battery Pack Battery Battery Compartment Cover Step 3 Replace the battery compartment cover and retaining screws. NOTE! If the HSDC scale fails to operate after battery replacement check to make certain that each of the six cells has been installed correctly. One cell installed backward will prevent the scale from operating. SCALE OPERATION Before weighing operations can begin it will be necessary to install batteries in the scale. Refer to the battery installation section of this manual for additional information. Hang the scale from a support that is strong enough to support the weight of the scale PLUS the weight of the material that is to be weighed. Hang the load receiving element on the hook on the bottom of the scale and press the ON/ZERO key. Look at the weight display. If the display does not indicate zero weight, press the ON/ZERO key again to reset the display to zero. Place the material to be weighed in the receiving element and read the weight in the scale display. Refer to the figure below for the identification of scale components: Weight Display Window Net Annunciator Low Battery Indicator OFF Key OFF G GROS S T TARE N ON NET ZERO 0 Zero Indicator GROSS, TARE and NET Keys ON/ZERO Key 3 SCALE OPERATION, Cont Scale Component Identification Press to turn the scale off. The auto-shutoff feature will turn the scale off automatically after a preselected time of inactivity (no motion). OFF Press to place the scale in the gross weight display mode (net indicator off). G GROSS Press to enter a new tare weight value equal to the current scale weight. The scale will automatically enter the net weight display mode (net indicator on). T TARE Press to enter the net weight display mode without entering a new tare weight value (net annunciator on). N NET Press to turn the scale on. If on, press to zero the weight display up to the preset zero limit (4% or 100% of the scale capacity). ON ZERO 0 The membrane keyboard is not to be operated with pointed objects (pencils, pens, fingernails, etc). Damage to keyboard resulting from this practice will NOT be covered under warranty. Annunciators • NET • • LO BAT Illuminated to signal that the batteries should be replaced. Illuminated to indicate the scale is in the net weight mode. If it is off, it indicates that the scale is in the gross weight mode. ZERO Illuminated to show that the scale weight is within 1/4 graduation of the center of zero. TARE WEIGHT ENTRY The HSDC has an automatic tare feature that allows you to enter tare weight up to the three least significant digits of the scale capacity. This tare weight feature is often used to subtract the empty container weight or other unwanted fixed weight values from the weight reading. See the PUSH BUTTON TARE setup mode section to activate this feature. The following table lists the maximum tare weight allowed for each model of the HSDC scale. MODEL HSDC-500 HSDC-200 HSDC-100 HSDC-40 HSDC-20 HSDC-100KG HSDC-40KG HSDC-20KG CAPACITY 500 lb X 0.2 lb 200 lb x 0.1 lb 99.95 lb x 0.05 lb 40 lb x 0.02 lb 20 lb x 0.01 lb 99.95 kg x 0.05 kg 40 kg x 0.02 kg 20 kg x 0.01 kg TABLE 1 4 MAXIMUM TARE WT 99.8 lb 99.9 lb 9.95 lb 9.98 lb 9.99 lb 9.95 kg 9.98 kg 9.99 kg TARE WEIGHT ENTRY, Cont. Pressing the TARE key will cause the currently displayed gross weight to be stored as the new tare weight and cause the scale to enter the net weight display mode. The net weight display mode is indicated by turning on the net annunciator. For example, on a HSDC-20, if the displayed gross weight is 2.00 lb and you press the TARE key, the 2.00 lb would be entered as the new tare weight. The scale would then enter the net weight mode and subtract the 2.00 lb tare value from the gross weight displaying a net weight of 0.00 lb. If you added another 2.00 lb to the platform, the display would indicate 2.00 lb of net weight. Pressing the GROSS key would return the scale to the gross weight display 4.00 lb. NOTE: Remember the scale will only weigh to its maximum capacity. Any combination of NET plus TARE weights over the scale capacity will result in a overload condition and display ot. For example, using the HSDC-20 from above, with tare weight of 2.00 lb, adding 19.00 lb to the platform will cause an overload condition. This is because 2.00 lb tare weight plus 19.00 lb load weight equals 21.00 lb gross weight, which exceeds the capacity of the scale. DISPLAY CODES During operation of the HSDC hanging scale you may encounter a special display message. The following lists display codes and their meaning. DISPLAY MEANING -oC- Scale overloaded, remove excess load to resume operation. UnSt Motion is present when attempting to power-up, zero the weight display or enter a tare value. UnLd The weight on the scale exceeds the zero range on power-on. Remove the load. LoAd= The scale load is less than the zero range on power-on. -oF- Attempting to display a negative number less than -999. CALb Indicates that the scale has not been calibrated or has been interrupted during the calibration process. Err Disallowed keyboard entry: attempted to zero with the weight outside the zero range. 5 CALIBRATION Your HSDC hanging scale has been calibrated prior to shipment and should not require recalibration before it is placed in service. A regular check of the instrument’s calibration should be made to ensure that its weighing accuracy is maintained. To check the calibration of your HSDC hanging scale, you must have a calibrated test weight or weights equal to the scale’s capacity. Begin by making certain that the scale is unloaded and that the display is indicating zero weight. Load the scale with the test weight(s) and observe the weight display. If the displayed weight is different from the total test weight value, calibration may be necessary. Note that a qualified scale technician should be consulted before any attempt at calibration is made. NOTE! This scale is provided with a means of attaching a seal to prevent access to the calibration switch. Calibration Procedure Step 1. Remove the seals (if present) from the calibration cover plate, then remove the two retaining screws and cover plate. Retaining Screw Cover Plate Seals Underside of Scale Step 2.
