Seca 334 Manual

Setting up the scale

The scale is fully assembled on delivery. Remove the packaging and place the scale on a firm, level surface.

Power supply

The scale is powered by batteries or a mains unit (option). The LC display has a low power consumption

10,000 weighing operations can be performed with one set of batteries. Once battery power is no longer sufficient, appears in the display.

Battery and mains unit (option)

If or appear in the display, you should change the batteries. You need six 1.5 V type AA round-cell batteries.

Carefully turn over the scale.
Press the tabs on the battery compartment and take off the cover.
Remove the used batteries and place the new batteries in the compartment.
Check that polarity is correct.
Close the cover.

Operation

Weighing correctly

Press the Start key with no load on the scale.

, and appear consecutively in the display. The scale is then automatically set to zero and ready for operation.

Place the baby on the scale.
Read the weight off the digital display.

Weight is displayed in 5 g increments up to 10 kg and in 10 g increments up to 20 kg.

Pressing the START key again switches off the scale.

Auto hold function

For weights above 0.4 kg, the HOLD function is activated automatically. The display flashes until a stable weight has been measured. The display is then frozen until the next weighing operation takes place. HOLD appears in the display.

Automatic shut-down/power-saving mode

To save power, the scale switches itself off after a short time if there is no load on it.

Switching the weight display

Switch on the scale. Weight is initially displayed in the last setting used, either in kilogrammes or pounds. To switch the weight display between kilogrammes and pounds, press the kg/lbs key.

Taring weight display (TARE)

The tare function is useful if an additional weight (for example a cloth or pad on the weighing surface) is to be ignored in the weighing result. Proceed as follows: press the TARE key while the additional weight is on the scale and wait until appears in the display.

The maximum weight which can be displayed is reduced by the weight of the objects already placed on the scale. You can now perform as many weighing operations as you like with this additional weight.

You can switch off TARE by pressing the TARE key again or by switching off the scale.

Use of differential display function

You can use this function for example to measure the intake of milk when breastfeeding or have Baby's increase in weight displayed since being last weighed. This function can be used to store an individual weight value and then use that value to form a difference - to detect the amount of milk ingested during breastfeeding, for example, or to see how a particular baby's weight has increased since it was last weighed.

To store the weight value, press the STORE key for approx. 2 seconds after the weighing operation is complete. The indicator is faded in. The weight value is now saved and will also remain stored once the scale is switched off.
With a subsequent weighing operation it is then possible to switch the display over to differential display, i.e. display of current value less saved value, by briefly pressing the STORE button.
When the differential display function is activated, appears in the display.
Briefly pressing the key again switches the function off again.

warning Note: If a new weight value is stored, the previous stored value will be overwritten. If the differential display function is activated with no load on the scale, the stored value is shown in the display as a negative value.

Cleaning

Clean the weighing tray and the housing as required using a domestic cleaning agent or a commercially-available disinfectant. Follow the manufacturer's instructions.
