INDICATOR HOUSING
Before opening the stainless steel indicator housing, make sure it is dry. If necessary wipe
the housing dry paying particular attention to the joint between the front panel and rear housing.
The re-assembly instructions should be accurately followed to ensure the IP rating is
maintained in service. NOTE: There are no user serviceable parts inside the indicator and all
service work should be carried out by the technical staff of your supplier.
RE-ASSEMBLY INSTRUCTIONS:
Position the front panel onto the rear housing and fit all six fixing screws finger tight.
Tighten the screws in the order shown in the diagram below to a torque of 12 kgf-cm. NOTE:
Over tightening the screws could impair the IP rating.
Tightening order:

BEFORE USING THE SCALE
To enable you to use this scale correctly, we suggest that you read this manual carefully.
INSTRUCTIONS FOR USE
1. The load placed on the weigh pan must NOT exceed the maximum weighing capacity of
the scale.
2. Protect the scale from high temperatures.
3. Avoid objects impacting with the scale. Do not drop loads onto the scale or subject the
weigh pan to any strong shock loads.
PREPARING TO USE THE SCALE
1. Locate the scale on a firm level surface free from vibrations for accurate
weight readings.
2. Adjust the four levelling feet (if fitted) to set the scale pan level.
3. Avoid operating the scale in direct sunlight or drafts of any kind.
4. If possible avoid connecting the scale to ac power outlet sockets which are
adjacent to other appliances to minimise the possibility of interference
affecting the performance of the scale.
5. Remove any weight that might be on the weigh pan before the scale is
switched on and avoid leaving weight on the pan for long periods of time
6. All goods weighed should be placed in the centre of the weigh pan for
accurate weighing. The overall dimensions of the goods being weighed
should not exceed the dimension of the weigh pan.
7. Once the scale has been powered on, it will go through an LCD display test
and it is ready for use when the display shows zero.
8. The scale requires 15~20 minutes warm up before operation to ensure best
accuracy
9. Please note when the
symbol keeps flashing on the screen, the
batteries need to be recharged.
