6. INSTALLATION
6.1 Mounting location – Environmental considerations
The mounting location must be such that the instrument is not subject to excessive vibrations, heat
or humidity. Avoid direct sunlight on the front of the instrument. The unit has to be installed at the
right height to allow an easy reading of the dis lay and convenient keyboard o eration.
AMBIENT : Storage - 10 to +70 0C.
TEMPERATURE O erating -10 to +40 0C.
HUMIDITY : 40 to 90% RH (non condensing).
VIBRATION : Severe vibration can affect the accuracy of weighing and damage
electric / electronic com onents.
AIR : The surrounding air should be dust free and not contain any corrosive
gasses or materials which could adversely affect the equi ment.

10. USING THE INDICATOR
10.1 Zeroing the scale
Sometimes the indicator’s dis lay shows a figure higher or lower than zero, although the scale
seems to be em ty. This may ha en, for instance, when water or dirt have gathered on the
surface of the scale and are difficult to be removed during the weighing o eration. This could be
also due to environmental conditions, which cause the center of zero to move from its initial
osition.
Pressing the ZERO key resets weight dis lay to zero, roviding a com ensation for the above
unwanted weights.
In order to zero the scale:
1. Wait for the scale to become stable
2. Press the key )
3. The dis lay shows Z E r o briefly
4. The current weight is set as the zero oint
5. The Zero annunciator “ zero “ turns on
.
..
. Zeroing is ossible only if the scale is stable and the indicator in gross mode
.
..
. Zeroing is ossible only if the weight on the scale is within + 2% of the scale ca acity (or +
10% de endant on how the zero range has been defined in the set u of the indicator). If
the weight is outside the zero range, ressing the zero key will have no effect
.
..
. The Zero oint acquired with this key will be in effect until a new zeroing o eration or ower
down.
10.2 Taring the scale
If the item to be weighed comes in a container, the scale needs to be tared, i.e. the weight of the
container needs to be measured and subtracted from the total weight (weight of container +
weight of the item), so that the net weight is acquired.
When the scale is tared, it o erates in the so called ‘NET mode’, which is indicated via the status
annunciator NET.
.
..
. Taring is ossible only if the scale is stable
.
..
. Taring is ossible only if the weight on the scale is within the scale ca acity

LD5208 USER MANUAL, REV. 0: NOVEMBER 2005

10.2.1 Taring with unknown tare weight
If the weight of the container is not known, in order to tare the scale:
 If the scale is already in NET mode (NET annunciator ON)
1. Press the key > in order to cancel the existing tare and return to gross mode.
 The scale is in GROSS mode
2. Place the em ty container on the scale, wait for the dis lay to stabilize and ress the key
> in order to measure the new tare
3. The weight dis lay is reset to zero and the NET annunciator is turned ON
4. Remove the em ty container. The weight dis layed is the tare with a negative sign.
5. Proceed with the weighing.
 To return to the GROSS weighing mode, ress the key > again. The indicator will show then
the gross weight, i.e. the total weight of the item lus the weight of its container.
10.2.2 Taring with known tare weight
If the weight of the container is known, the scale can be tared by the manual entry of this known
weight. Similarly, the weight of the container will be subtracted from the total weight measured by
the scale and the NET weight will be acquired.

10.4 Piece counting
You can enter the PIECE COUNTING MODE by ressing the key &.
In this mode the res ective status annunciator will switch ON .
Pressing this key again will get you back to the WEIGHING MODE .
Piece counting can be effected in 2 ways
 Piece counting by sam ling
 Piece counting by entering the average iece weight
10.4.1 Piece counting by sampling – Function 51
First you have to determine the average iece weight. This is done with the method of sam ling.
You have to ut a small sam le on the scale (i.e. a known quantity of items), weigh this sam le
and enter the known number of ieces that com rise the sam le (sam le size). The indicator
divides the weight of the sam le with the number of ieces and stores the average iece weight in
its memory .
.
..
. Sam le size should not be higher than 99 or less than 5 and sam le weight
Piece counting procedure
1. If the sam le is stored in a container, tare the scale first
2. Put the sam le on the scale
3. Press key > and kee ressed for about 3sec
4. Dis lay shows F n 0 0 . Ty e in the number 51, using key ~ to increment the flashing digit
and key > to move one digit to the right
5. Press key ( to acce t the value
6. The dis lay shows P C S X X
7. Ty e in the sam le size and ress (
8. The indicator calculates the average iece weight and stores it in its memory
9. The dis lay shows the number of items that com rise your sam le.
10. The indicator is already in the iece counting mode – Status annunciator pcs is ON
11. Add an unknown quantity of items on the scale
12. The dis lay shows the number of ieces
To exit the iece counting mode and return to the weighing mode, ress key &
