Hornady GS-350 - Manual (Page 2)

KEY PAD FUNCTIONS:
ON/OFF Key
a) Press and hold to turn unit on or off.
b) Once unit is on, this key operates the tare function. Press to compensate for
the weight of weighing tray or other object.
MODE/CAL Key:
a) Press and hold to begin calibration procedure (see Calibration Procedure).
b) Press and release to change weight unit, i.e., from grams to grains.
CALIBRATION:
Important: always allow a minimum of thirty seconds for the scan to stabilize.
During prolonged periods of use repeat this procedure at regular intervals for
optimum accuracy.
Note: Any attempt by the end user to internally calibrate the scale will void warranty.
DIGITAL AUTO CALIBRATION PROCEDURE:
1. Place scale on a flat surface in a sheltered area.
2. Turn scale on by pressing ON/OFF key. Allow unit to stabilize for at least
thirty seconds.
3. Press and hold CAL key until the display shows a flashing weight reading.
The flashing weight reading indicates the correct weight that must be
placed on the tray.
4. With the display still flashing, press the ON/OFF key. The display will read
CAL 0.
5. Wait for 3 seconds and then gently place the correct calibration weight in
the center of the tray.
6. When the calibration is complete the unit will briefly display
CAL F and then return to normal operating mode. The calibration is
complete when the display correctly shows the weight that is placed on the
weighing tray and the display has stabilized.
7. Remove the calibration weight and press the TARE ( <0> ) key to reset the
zero point.
Note: If CAL E appears instead of CAL F, this indicates an error has occurred.
Turn the scale off and repeat the procedure.
OPERATION:
1. Place scale on a flat surface in a sheltered area.
2. Press and hold the ON/OFF button to turn the scale on.
3. Open draft shield and place tray on weighing platform. (You may also place
objects directly on the weighing platform.)
4. Allow the scale to stabilize for at least 30 seconds. When initially turned on,
the scale will read 8888 before returning to zero.
5. Gently place object(s) to be weighed in the weighing tray. Do not overload.
6. Wait for reading to stabilize.
7. Read weight.
8. To change weighing units (from grams to grains) press the MODE/CAL key.
FEATURES:
DIGITAL AUTO CALIBRATION:
Allows for convenient user digital calibration from the keypad.
POWER UP TEST:
When the unit is initially turned on, all segments of the display will appear. This
will remain for approximately 3 seconds. The scale will then reset to zero. This
is an internal self-test procedure.
RIGHT READING INDICATION:
A right facing arrow will appear on the right side of the display to indicate
the weighing mode currently in use. When weight is placed on the tray, this
arrow will disappear while the scale stabilizes and will reappear once the
stable weight reading is achieved.
OVERLOAD:
When a load that exceeds this unit’s capacity is applied to the weighing platform,
an E (error) will appear on the display. Remove this load immediately. The unit
should then return to normal operation unless damage has occurred.
NEGATIVE VALUE RECORDING:
Any “tared” value or value left in memory will be displayed as a negative
number once all weight is removed from the unit. Press the
TARE ( <0> ) key to
return the unit to zero.
