BATTERY INSTALLATION

Before weighing operations can begin it will be necessary to install the batteries in the HSDC hanging scale. 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

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.

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 CAPACITY MAXIMUM TARE WT

HSDC-500 500 lb X 0.2 lb 99.8 lb HSDC-200 200 lb x 0.1 lb 99.9 lb HSDC-100 99.95 lb x 0.05 lb 9.95 lb HSDC-40 40 lb x 0.02 lb 9.98 lb HSDC-20 20 lb x 0.01 lb 9.99 lb HSDC-100KG 99.95 kg x 0.05 kg 9.95 kg HSDC-40KG 40 kg x 0.02 kg 9.98 kg HSDC-20KG 20 kg x 0.01 kg 9.99 kg

TABLE 1

Page 7

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.

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.
