ICON KEYS DESCRIPTION
Numerical Keys Press to input digit data, e.g. piece weight and numbers
of samples.
~
Decimal Key Press to set decimal point when taring and sampling
Zero Key Press to set the scale to zero.
Tare Key Press to subtract out the mass of the weighing
container.
Sample Count Key After setting the sample count number, press to save
the sample count data.
Piece Weight Key After setting the sample piece weight, press to set the
given piece weight..
Clear Key Press to clear the input data or reset the piece weight.
Alarm Key Press to set up the upper and lower bounds of weights
and pieces.
Subtotal Key Press to memorize and aggregate the counting results
and weights.
Replay Memory Key Press to view the accumulated weights and pieces in
memory.
This is a compound key whose function varies
according to the Pr settings. When Pr is set as LP50-1,
press to print out LP-50 label format. Press and hold

Using the Digital Counting Scale
Zero function
When there is no weight loaded and the scale shows trivial weight, press the to
clear the weight and set the scale to zero.
1. Press the key to clear the trivial weight. The WEIGHT display should be cleared.
2. ▼should show above the icon.
Tare function
The Tare Function subtracts out the mass of the weighing container.
key to tare the current weight
Push
1. Place sample container on the weighing pan.
2. Press key to turn on the Tare function. ▼is displayed above the icon and the
WEIGHT display shows zero.
3. If the sample container is removed after the tare operation, the WEIGHT display should show
a negative value.
Clearing the tare weight:
1. Remove the sample container from the pan and press the key. ▼on the indicator is
turned off. The WEIGHT display again shows zero.
Sampling method:
The two methods are covered below:
A. Piece Count setting (If the piece weight of the sample is not known)
1. Place certain number of the sample parts on the scale pan, the weight value
should shows on the WEIGHT display.
2. Enter the number of the sample parts, it will show and flash on the PIECE
WEIGHT display.

3. Press the key. Now the average piece weight shows on the PIECE
WEIGHT display. The sampling number will show on the PIECES display.
B. Piece Weight setting (If the piece weight of the sample is known)
1. Enter the piece weight value by numerical keys. It will show and flash on the
PIECE WEIGHT display.
2. Press the key. The piece weight will fix on the PIECE WEIGHT display.
Place samples on the scale pan directly and the PIECES display will show the
number.
Clearing input data, piece weight, and
accumulated weights
1. Press the key to clear the numerical input or the previous piece weight.
2. In Memory mode, press the key to clear the subtotal amount in memory.
Alarm function
A. Piece weight and sample weight are not enough:
1. When average piece weight or pre-set piece weight is deficient, the ▼
signal of LIGHT WEIGHTS will show and flash, the operator may continue
working. However slight inaccuracy may occur.
2. When the sample weight is deficient, the ▼signal of LIGHT will show and
flash, the operator may continue working. However slight inaccuracy may
occur when sampling. Using more samples for sampling is suggested under
such condition.
B. Quantity and weight alarm:
It can set both high and low limit or specific value alarm of the quantity and weight
as well.

-->Establish the current keyed-in value as upper bound of weight.
--> Establish the current keyed-in value as lower bound of weight.
--> Establish the current keyed-in value as upper bound of quantity.
--> Establish the current keyed-in value as low bound of quantity.
When weight alarm is set, the ►indicator left to Go icon on the WEIGHT Display
will show.
When the weight is higher than upper bound, the ►indicator left to Go icon will
disappear while the ►indicator left to Hi icon will flash and the beep will sound.
If the weight is lower than lower bound, the ►indicator left to Lo icon will flash and
start beep sounds.
When pieces alarm is set, the ►indicator left to Go icon on the PIECES Display
will show.
When the pieces are higher than upper bound, the ►indicator left to Go icon will
disappear while the ►indicator left to Hi icon will flash and the beep will sound.
If the pieces are lower than lower bound, the ►indicator left to Lo icon will flash and
start beep sounds.
Operation of M+
1. Load the weight on the scale after sampling.
2. Press to accumulate the weighing result including weights and pieces in
memory. When a beep sounds, Memory indicator appears on the LCD.
3. Clear the load on the weighting pan and place another load on the weighing pan.
4. When the scale is stable, press again. After a beep sound, the second data
has been recorded. ( The user may re-sample or not )
zAfter each recording, if the load on the weighing pan is not cleared, pressing
will result in the long beep and the scale will not be able to record the next
weighing result.
zThe scale can save up to 180 weighing results.

Operation of MR
1. In weighing mode, press to recall the accumulated weighing results. “WT” is
displayed in WEIGHT Display. The Total Weight is displayed in the PIECE
WEIGHT Display and the total accumulation is displayed in the PIECES Display.
2. Press again. The WEIGHT column is cleared and displays “PCS” and the
total piece count is displayed in the PIECE WEIGHT Display. The total
accumulation is displayed in the PIECES Display.
3. Press to clear the stored data from the memory, and the scale will return to
normal weighing mode.
4. If the user doesn’t clear the stored data, press again, the scale will return to
normal weighing mode, too.
