INDICATOR HOUSING
Before opening the stainless steel indicator housing, make sure it is dry. Ifnecessarywipe
the housing drypaying particular attention to the joint between the front panel and rear housing.
The re-assemblyinstructions should be accuratelyfollowed to ensure the IPrating is
maintained in service. NOTE: There are no user serviceable parts inside the indicator and all
service work should be carried out bythe technical staffof your supplier.
RE-ASSEMBLYINSTRUCTIONS:
Position the front panel onto the rear housing and fit all sixfixing screws finger tight.
Tighten the screws in the order shown in the diagram belowto a torque of12 kgf-cm. NOTE:
Over tightening the screws could impair the IPrating.

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 NOTexceed the maximum weighing capacityof
the scale.
2. Protect the scale from high temperatures.
3. Avoid objectsimpacting with the scale. Do not drop loadsonto the scale or subject the
weigh pan to anystrong shock loads.
PREPARINGTO USE THE SCALE
1. Locate thescaleona firm level surfacefree from vibrations foraccurate
weight readings.
2. Adjust thefour levelling feet (if fitted) toset thescale panlevel.
3. Avoid operatingthescaleindirect sunlight or drafts of anykind.
4. If possible avoid connecting thescaleto ac power outlet sockets which are
adjacent toother appliances tominimise thepossibilityof interference
affectingtheperformance of thescale.
5. Remove anyweight that might be onthe weigh pan before thescale is
switchedon and avoid leaving weight on the panfor long periods of time
6. All goods weighed shouldbeplaced in thecentre of theweigh panfor
accurateweighing. The overall dimensions of the goods being weighed
shouldnot exceedthe dimensionof theweigh pan.
7. Oncethe scale has beenpowered on, it will gothrough anLCD displaytest
and it is readyforuse when the display shows zero.
8. The scalerequires 15~20 minutes warm up beforeoperation toensurebest
accuracy
9. Pleasenote when the symbol keeps flashingonthescreen, the
batteries need to be recharged.
