8.4 Operation
- Never overload the product. Exceeding its maximum weight capacity can damage the product.
- Consult an expert when in doubt about the operation, safety or connection of the device.
- If it is no longer possible to operate the product safely, take it out of operation and protect it from any accidental use. DO NOT attempt to repair the product yourself. Safe operation can no longer be guaranteed if the product:
– is visibly damaged,
– is no longer working properly,
– has been stored for extended periods in poor ambient conditions, or
– has been exposed to considerable strain during transport.
8.5 (Rechargeable) batteries
- Pay attention to correct polarity when inserting the batteries.
- If you do not plan to use the product for an extended period, remove the batteries to prevent damage from leaking. Leaking or damaged batteries may cause acid burns if they come into contact with your skin. Always use suitable protective gloves when handling damaged batteries.

Operation
10.1 Power supply With batteries
- Remove the battery compartment cover on the base of the product.
- Insert two AA batteries (included). Ensure the batteries are inserted with the correct polarity. The positive and negative terminals are marked on the batteries and on the inside of the battery compartment cover.
- Replace the battery compartment cover.
Note:
– Replace the batteries when “LO” appears on the display.
With external DC power supply
- Connect a suitable DC power supply (5 V/DC, 0.5 A) to the DC socket (6).
Observe the plug polarity requirements as indicated in the technical data.
Note:
– If batteries are inserted, the product will only be operated via the
external DC power supply until it is disconnected.
10.2 Setting up the scale and switching it on/off
-
Before use, allow the scale to reach room temperature for at least 1 hour in order to obtain the best measuring results.
-
Screw in the 4 feet.
-
Place the scale on a solid, level and dry surface.
-
Use the spirit level (7) to check that the scale is aligned correctly. If necessary, adjust its position with the adjustable feet.
-
To switch on the scale, press the ON/OFF button (9).
The display (2) will switch on and show the value “0.00”. -
Press the MODE button (4) repeatedly to select the desired unit: – g → ct → dwt → gn → T → oz
Note:
– You can change the desired unit at any time. -
Press the ON/OFF button (9) again to switch off the scale.
10.3 Weighing objects
-
Place the object you want to measure in the middle of the weighing plate (1).
-
Wait until the reading stabilises and the symbol 0 appears on the display.
The weight of the object will be displayed. -
Remove the object from the weighing plate (1).
Important:
– If the weight exceeds the weighing range, “O_Ld” will appear on the the
display. In this case, remove the object from the weighing plate immediately.
– You can use the supplied cover to prevent atmospheric influences from fal-
sifying the measuring result.
10.4 Using the tare function
-
Place a suitable holder onto the weighing plate (1). Wait until the display stabilizes and shows the weight.
-
Press the TARE (5) button.
The display will show the value “0.00”. -
Place the object you want to weigh in the container. Wait until the display stabilises.
The net weight of the object will be displayed. -

10.5 Using the counting function
The counter function allows you to count the quantity of several objects
with the same weight (e.g. small screws).
-
Place 25, 50, 75 or 100 of the objects you want to weigh on the weighing plate
(1). Wait until the display stabilises. -
Press and hold the PCS button (3) until “pcs” appears on the display.
-
Press the MODE button (4) repeatedly until the number of objects placed on the weighing plate is displayed (25, 50, 75 or 100).
-
Press the PCS (3) button.
The reference value will be stored until you set a new value. -
Place the objects that you want to count onto the weighing plate.
The display will show the number of objects. -

Press the MODE button (4) to return to the normal weighing mode.
10.6 Calibrating the scale
The scale is pre-calibrated before delivery. If the measurements are
inaccurate, try replacing the batteries first. If the accuracy does not
improve, you can recalibrate the scale using a suitable calibration weight of
200 g or 500 g.
-
Press and hold the CAL button (8) until the calibration weight (200 g or 500 g) is displayed.
-
Press the TARE button (5) until the desired calibration weight (200 g or 500 g) is displayed.
-
Press the CAL button (8) again.
“CAL” will appear on the display and the selected calibration weight will flash. -
Place the calibration weight on the weighing plate (1).
-
Wait until “PASS” appears on the display.
-
Remove the calibration weight from the weighing plate (1).
Calibration is now complete.
10.7 Setting the power-off timer
By default, the scale powers off after 5 minutes of inactivity. Alternatively,
you can set a different power-off time:
-
Press and hold the TARE button (5) until the power-off time appears on the display.
-
Press the TARE button (5) several times until the desired power-off time is reached:
– “1” (1 min) → “3” (3 min) → “5” (5 min) → “-” (disabled) -
Press the MODE button (4) to confirm your changes.

Disposal
12.1 Product
This symbol must appear on any electrical and electronic equipment placed on
the EU market. This symbol indicates that this device should not be disposed
of as unsorted municipal waste at the end of its service life.
Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose
of it separately from unsorted municipal waste. Spent batteries and
accumulators, which are not enclosed by the WEEE, as well as lamps that can be
removed from the WEEE in a non-destructive manner, must be removed by end
users from the WEEE in a non-destructive manner before it is handed over to a
collection point.
Distributors of electrical and electronic equipment are legally obliged to
provide free take-back of waste. Conrad provides the following return options
free of charge (more details on our website):
- in our Conrad offices
- at the Conrad collection points
- at the collection points of public waste management authorities or the collection points set up by manufacturers or distributors within the meaning of the ElektroG End users are responsible for deleting personal data from the WEEE to be disposed of.
It should be noted that different obligations about the return or recycling of
WEEE may apply in countries outside of Germany.
12.2 (Rechargeable) batteries
Remove batteries/rechargeable batteries, if any, and dispose of them
separately from the product. According to the Battery Directive, end users are
legally obliged to return all spent batteries/rechargeable batteries; they
must not be disposed of in the normal household waste.
Batteries/rechargeable batteries containing hazardous substances are labelled
with this symbol to indicate that disposal in household waste is forbidden.
The abbreviations for heavy metals in batteries are:
Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable) batteries, e.g.
below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your
municipality, our stores or wherever (rechargeable) batteries are sold. You
thus fulfil your statutory obligations and contribute to environmental
protection.
Batteries/rechargeable batteries that are disposed of should be protected
against short circuit and their exposed terminals should be covered completely
with insulating tape before disposal. Even empty batteries/rechargeable
batteries can contain residual energy that may cause them to swell, burst,
catch fire or explode in the event of a short circuit.
