2. Preparation
2.1. BEFORE SING THE SCALE
To enable you to use this scale correctly, we suggest that you read this manual carefully.
1. Do not use scale in areas ith excessive ater and don’t spray the scale or indicator ith
ater hen cleaning. Remove all ater from the scale and indicator ith a clean dry cloth.
2. The load placed on the platform must not exceed the maximum eighing capacity of the
scale.
3. Keep the scale a ay from high temperatures and damp conditions.
4. If the scale is not going to be used for some time, please clean it and store it in a plastic
bag in dry conditions. A desiccant sachet may be included to prevent moisture build up.
5. If the scale is not going to be used for some time, the internal rechargeable battery should
be recharged every three months.
6. Before using the scale after a long period of storage, please ensure that the internal
battery is fully charged. NOTE: Care should be taken not to leave the internal battery on
charge for too long, as this may decrease the life of battery.
2.2. PREPARING THE SCALE FOR SE
1. Unpack the scale carefully and place it on a firm surface. Lift the platform cover off the
scale and remove any packing materials that may be underneath. Replace the platform on
to the rubber support pads. The platform has a plastic protection film hich can be
removed to expose the stainless steel surface or left in place if desired.
2. For accurate eight readings locate the scale on a firm level surface free from vibrations. If
the scale platform cover is removed a bubble level can be observed on the lo er eigh
frame to check the scale is level. The four adjusting feet can be used for levelling the
scale. The bubble should be inside the centre black circle.
3. Avoid operating the scale in direct sunlight or drafts of any kind.
4. Remove any eight that might be on the eigh pan before the scale is s itched on and
avoid leaving eight on the pan for long periods of time.
5. Once the scale has been s itched on, it ill go through a LCD display test and then re-
zero to be ready for use.
6. For best accuracy s itch the scale on for 15~20 minutes before use.
7. Please note hen the symbol appears on the screen, the batteries need to be
recharged.
8. All goods eighed should be placed in the centre of the eigh pan for accurate eighing.
The footprint of the goods being eighed should not overhang the sides of the eigh pan.
9. The acceleration due to gravity varies around the orld. The force on the scale is a product
of the gravity value and the mass placed on the scale to eigh. As the gravity value can
vary in different orld locations so can the eight displayed for the same mass. The Scales
have been calibrated for a gravity value (acceleration due to gravity) of g=9.803 m/s2.
Discrepancies in readings at the location of installation could be due to a different gravity
value and adjustment on site of the scale calibration may be needed.
10. The calibration access port is in the indicator on the side of the case. To access the
LOCK/ADJ s itch remove the small rectangular cover.

7.2. RELAY O TP T
7.2.1.Relay Output
The relays act as signal output in the check- eighing mode. When an object’s
eight value reaches one of the setting points (HI, OK, LOW), the relay outputs a
signal through PIN 1, PIN2, or PIN 3. Set the check- eighing values by entering
the check- eighing configuration (please refer to 6.1 for operation). The relays are
recommended for s itching up to 24V AC/DC 2A.
