TARE FUNCTION (NET WEIGHT)
The tare function allows the display to be reset to
zero at any time.
The Tare Function may be used to eliminate the
weight of a carrier (container, wrapper, liner, etc.)
from a sample, when the weighed material is held
in a carrier and only the net weight of the material
is desired.
1. Insure there is no material in the spatula scoop.
2. Place the unit on a fl at level surface.
3. Press the ON/TARE button to turn the unit on.
4. Verify that the display reads zero.
If the display does not read zero, press the ON/TARE
button to zero the display. The display will reset to
zero approximately 1 second after the ON/TARE
button is pressed.
5. Place the carrier only (without material) into the
spatula scoop.
6. Once the reading stabilizes, press the
ON/TARE button. The display will reset to zero
approximately 1 second after the ON/TARE
button is pressed.
7. Remove the carrier from the spatula scoop.
The weight of the carrier will now be removed from
the weight shown on the display. When all material
is removed from the spatula scoop, the weight of
the “tared” carrier will be displayed as a negative
number.
8. Place the material to be weighed (including the
carrier) into the spatula scoop.
9. Return the unit to the fl at level surface and
press down on the spatula handle to prevent
the handle from lifting off of the level surface.
10. Read the value on the display.
NOTE: The total weight of the carrier plus the material
must not exceed the capacity of the unit.
TARE FUNCTION (ADD & WEIGH)
The tare function allows the display to be reset to
zero at any time.
The Tare Function may be used to “Add & Weigh”,
allowing material to be added to the spatula scoop
while only displaying the weight of the added
material (net weight added).
1. Insure there is no material in the spatula scoop.
2. Place the unit on a fl at level surface.
3. Press the ON/TARE button to turn the unit on.
4. Verify that the display reads zero.
If the display does not read zero, press the ON/TARE
button to zero the display. The display will reset to
zero approximately 1 second after the ON/TARE
button is pressed.
5. Place or scoop the material to be weighed into
the spatula scoop.
6. Return the unit to the fl at level surface and
press down on the spatula handle to prevent
the handle from lifting off of the level surface.
7. Read the value on the display.
8. Press the ON/TARE button. The display will
reset to zero approximately 1 second after the
ON/TARE button is pressed.
The weight of the material in the spatula scoop will
now be removed from the weight shown on the
display.
9. Place additional material into the spatula
scoop.
10. Read the value on the display. The value
shown on the display will be the weight of the
material that has just been added.
Repeat steps 8 through 10 as desired.
NOTE: The total weight of the material in the spatula
scoop must not exceed the capacity of the unit.
When all material is removed from the spatula
scoop, the weight of the “tared” material will be
displayed as a negative number.
ACCUMULATION FUNCTION (∑)
The accumulation function allows the weights of
material to be added together for a total accumu-
lated material weight without having to combine
the material in the spatula scoop to obtain the total
accumulated material weight.
1. During measurement, if the weight is more than
0.5 grams (0.02 ounces), pressing the ∑ /UNIT
button will activate the accumulation feature
( ∑ will appear on the display).
2. To accumulate additional weights, remove the
material, load additional material and press the
∑ /UNIT button again, the display will now show
the total of the accumulated weights.
Repeat step 2 as often as needed to continue to
add to the total accumulated weight.
NOTE: To accumulate weights, each individual weight
must be more than 0.5 grams (0.020 ounces),
but not greater than 300 grams (10.580 ounces).
The maximum total accumulated weight must not
exceed 3000 grams (105.81 ounces).
3. To exit the accumulation mode, press the
∑ /UNIT button when the spatula scoop is empty.
HOLD FUNCTION
The Hold Function will “freeze” the display at the
current reading for ten (10) seconds.
To “freeze” the display at the current reading, press
the HOLD button (“HOLD” will appear on the
display). The “frozen” value will remain on the
display if material is removed from, or added to,
the spatula scoop.
NOTE: The weight being measured must be greater
than 0.0 ounces/grams in order for the Hold
Function to be used. While in this mode, pressing
the ∑ /UNIT button will exit from the Hold Mode.
Press the “HOLD” button again to return to the
weighing mode, or wait for 10 seconds for the display
to automatically return to the weighing mode.
AUTOMATIC SHUTOFF
If no button has been pressed for two (2) minutes
and the change in the weight being measured is
less than 1 gram (0.035 ounces), the Automatic
Shutoff feature will turn the unit off to preserve
battery life.
