DC-782 Operation Manual
Note:
The following SPEC codes must be set properly to allow these operations before continuing: SPEC 25, Bit 3 - MANUAL
TARE CANCELLATION sets whether or not the tare weight can be cancelled from the keyboard. SPEC 25 also controls whether
TARE SUBTRACTION (Bit 2) and TARE ACCUMULATION (Bit 1) are allowed or inhibited and whether AUTO TARE CLEAR WHEN
REZERO (Bit 0) takes place or not. SPEC 26 controls whether the scale allows DIGITAL TARE entry (Bit 3), whether the scale can
do ACCUMULATION WHEN TARE (Bit 2), if there will be ZERO TRACKING WHEN TARE (Bit 1) and WEIGHT RESET WHEN
TARE (Bit 0). SPEC 27 sets whether or not TARE AUTO CLEAR is activated (Bit 3). (For further instructions on how to set the
specifications, see Section 3.2.1)
5.2.1
One Touch Tare (When the Tare Weight is Unknown)
1. While in the weighing mode, place a bin, box or other weight to be tared out on the platform.
2. Press the
TARE
key to subtract the tare weight. The
Net
annuciator will light up and the
Weight
display
should now show
0
.
3. If you remove the tare weight from the platform, the tare weight will show as a negative weight in the
weight window and the
Net
annunciator will remain lit.
NOTE:
This tare weight will be overridden by the weight stored with an Item Code when you call up an Item Code.
4. To clear this tare weight and return to the Weighing Mode, press the
TARE
key again. The
Net
annunciator will not longer be lit.
5.2.2
Digital Tare (When Tare Weight is Known in Advance)
1. While at the stand-by screen, enter the known tare weight by using the numeric keypad.
2. Press the
TARE
key to subtract the tare weight. The
Net
annunciator will light up and the tare weight
will be displayed in the weight display.
NOTE:
This tare weight will be overridden by the weight stored with an Item Code when you call up an Item Code.
3. To clear this tare weight and return to the Weighing Mode, press the
TARE
key again. The net
annunciator will no longer be lit.
NOTE:
For digital tare entry, the decimal must be in the appropriate place as it would be displayed in the weight display. For
example, .250 would be entered as 0.250, not .250. The weight display shows weight entered with a negative sign indicating that
it is a tare weight.
5.2.3
Tare Addition or Subtraction
Two tares can be accumulated or subtracted using the
TARE
key as well. Tare weights cannot be accumulated or
subtracted by digital entry.
NOTE:
SPEC 25, Bits 2 and 1 must be set to 00 to enable Tare Accumulation and Tare Subtraction. (For further
instructions on how to set the specifications, see Section 3.2.1)
1. Place the container, box or item to be tared on the platform and press the
TARE
key. The weight display
should show 0, the
Net
annunicator will illuminate and the tare weight will appear in the Tare display.
2. Place another tare weight on the platform and press the
TARE
key again. This will add the two tare
weights together (Tare Addition).
3. Tare weights can be subtracted individually by removing one from the platform and pressing the
TARE
key again. To clear all the tare weights and return to the Weighing Mode, remove all the tare weights and
press the
TARE
key. The
Net
annunicator will no longer be lit.
5.3
Entering Unit Weights
Entering unit weights can be done either by sampling, as presented in Section 5.3.1, or by key entry as described
in Section 5.3.2.
NOTES:
SPEC 04 - EXTENT OF INSUFFICIENT SAMPLES controls unit weight sampling. The default setting for the SPEC is 00:
0.1 percent. (For further instructions on how to set the specifications, see Section 3.2.1)
The Benefit of Unit Weight per 1000 Pieces Over Unit Weight per 1 Piece
Your DIGI DC-782 scale displays the unit weight calculated per 1000 pieces. Why is this a more accurate way to
display unit weight than the more common unit weight per individual piece? The scale’s internal microprocessor
calculates unit weights to 7 or 8 decimal places. However, the scale display generally can only show Unit Weight
to 5 characters. If this Unit Weight is recorded from the scale display and entered by key entry, this can introduce
errors in the Unit Weight and consequently in the counts. This error increases as the Unit Weight of the parts
being counted decreases.
