7. Operation
7-1 Basic Weighing
7-1-1 Weighing
Place item to be weighed on the scal e. The Weight
window shown is 2.000kg, Gross Weight.
7-1-2 Tare & Preset Tare
Tare
When weighing a sample that must be held in a container, taring stores the container weight
into memory.
1) Under the weighing mode, place
the container on the scale, weight
window shown is 0.500kg. Press the
Key TARE to complete tare action.
The symbol appears and with
symbol “ ” pointing at “NET”.
2）To clear tare, with an empty pan, Press
down the key TARE or key ZERO.
Preset Tare
1) Under the unload condition , Enter tare
value using the numeric keys together with
key ●, then press key TARE. The weight
window displays the tare value.
2) Put the load on the container, the scale will automatically deduct the value of the container
from the total value.
Note: during the process of Tare or Preset Tare, if the load and container are not removed,
press zero to check the gross weight.
JWI-700C 12
7-1-3 Unit Switch Operation
1) Press key SMPL while powering on the scale.
2) Key in 1132 via numeric keys.
3) Again press key SMPL to enter unit selection
mode. Numeric key 1 is to toggle between kg
and Lb units.
4) Press key SMPL to save, and then press key ZERO to return to the weighing mode.
7-2 Basic Counting
7-2-1 Upper & Lower Quantity Limit Check ing
1) Under the weighing mode, press and
hold key MC/CK to initial upper/lower limits
setting. (“ ” is blinking.)
2) Use numeric keys to set the upper/lower
Limits. Key ● is to save upper limit value
and advance to the lower limit setting.
3) When setting is completed, again press key MC/CK to return to weighing and checking
mode.
4）To cancel checking action , long press key MC/CK, then press key “·” twice .Checking
action is cancelled, with “ ”displays momentarily before the screen go back to zero mode.
7-2-2 Entering a Known Unit Weight
1) Under the weighing mode, use the numeric
keys together with key “·” to input unit weight
value, and then press UWS.
2）Put the article on the weighing pan , the
scale starts counting.
JWI-700C 13
Note: Symbol “ ” points at “UW” when entered unit weight is lower than 4/5 of scale division.
7-2-3 Sample Counting & ACAI
Sample Counting
1) Place samples onto the weighing pan
(Or into a tared container) and input the
quantity with numeric keys, then press key SMPL.
The unit weight is calculated, with Symbol “ ” Pointing
at “ACAI”
.
Note:
●The larger the sample size, the more accurate unit weight.
●Symbol “ ” points at “SMPL” when calculated unit weight is lower than 4/5 of scale
division or the quantity of sample is less than 10 pieces.
2) Remove the samples and put the load on, the scale begins to count.
3) Press key CE to return to the weighing mode.
ACAI
Automatic Counting Accuracy Improvement (ACAI) results in a more accurate count by
increasing the reference weight without the need to count additional parts. A higher reference
weight is im port ant w hen there is a risk o f inc onsi ste nt pi ece w ei ght s or i f t he r e ference w eig ht
is close to the minimum. ACAI uses an initial averaging unit weight to count additional pieces
that are placed on the scale .after a few seconds, the scale gives a beep as the new higher
reference weight is used to recalculate the averaging unit weight. The process can be
repeated as long as the additional weight is less than the previous reference weight . Once
this limit is exceeded ACAI is turned off.

7-2-4 Accumulation, Accumulation Display and Accumulation clear
1) Enter the indicated unit weight, press key UWS
and put first piece of load on the weighing pan
(or into a tared container). (Refer to 7-2-2)
2) Press key M+, the first accumulation event
is displayed momentarily before Symbol “ ”
pointing at
“M+”. The display reverts to normal
weighing mode in a second .Remove the fir st piece
of load.
JWI-700C 14
3) Put the second piece of load on, then press key M+ to add the seco n d accumulation even t
into memory. Repeat step 2-3 till accumulation actions are finished.
Note: Maximum is 99 pieces.
Accumulation display
Press key MR to displays the total accumulation data (weight, count and number of
weighments) and the first 10 accumulation events in detail.
Accumulation clear
To clear the total accumulation da t a or the fir st 10 accu mula t ion events, Press key MC/CK
while the data is displayed. Symbol “ ” disappears when the total accumulation data is
deleted.
