Labbox METRIA P Electronic Pocket Scale

Product Information

The Electronic Pocket Scale is a portable weighing device designed for accurate measurement of small objects. It has a compact size and can be easily carried around. The scale comes with various weight capacities ranging from 10g to 10000g and offers high accuracy with increments of 0.1g, 0.01g, 0.001g, 1g, 0.2g, or 0.05g depending on the model. It supports multiple weighing units including grams (g), ounces (oz), troy ounces (ozt), pennyweights (dwt), grains (gn), carats (ct), taels (t), and ticals (tl). The scale is powered by either two AAA batteries or one CR2032 battery and operates within a temperature range of 10 to 30 degrees Celsius.

Product Usage Instructions

Calibration:

1. Turn on the scale by pressing the I/O (switching key).
2. Press and hold the M (units key) until the LCD displays CAL.
3. Press the M (units key) again, and the CAL will flash followed by a number indicating the weight to be placed on the platform.
4. Put the required standard test weight on the platform and wait for 3 to 4 seconds. The LCD will show PASS.
5. Remove the weight and press the I/O (switching key) to turn off the scale. Calibration is now finished!
6. If a calibration error occurs, FAIL will be displayed. Please repeat steps 1-5.

Counting Function (With PCS or C key):

1. Select a sample of 25, 50, 75, or 100 pieces from the objects to be counted.
2. After opening the scale, place the sample on the platform.
3. Press and hold the PCS (counting key) for two seconds, and you will see the selected sample number displayed.
4. Press the M (units key) to view different sample numbers (25, 50, 75, 100, etc.). Select the correct number corresponding to your sample.
5. Press the PCS (counting key) to confirm the selected sample number.
6. Now you can put the objects you want to count on the platform, and the LCD will display the actual number of objects.

OPERATION

Place scale on a horizontal flat surface.

1. Press “I/O” (switching key).
2. Wait until 【0.0】(or 【0.00】【0.000】) is displayed stably.
3. Put the object(s) on the weighing platform.
4. Wait until the reading is displayed stably. You can read it.
5. Press “M” (units key), you can switch among the weighing units.

TARE WEIGHING

1. Turn on scale as described above.
2. Place the “tare item” on the platform.
3. Press “T” (tare key) and wait until 【0.0】(or 【0.00】【0.000】) is displayed.
4. Add the “net-weight-item”.

CALIBRATION

1. Turn on the scale by pressing “I/O” (switching key).
2. Press “M” (units key) and hold it until LCD displays “CAL”.
3. Again press “M” (units key), the “CAL” will flash and followed by a number which is the weight you need to put on the platform.
4. Put the required standard test weight on the platform and wait 3 to 4 seconds, the LCD will show “PASS”.
5. Remove the weight and press “I/O” (switching key) to turn off the scale. It is ok, the calibration is finished!
6. If a calibration error has occurred, “FAIL” will be displayed. Please repeat step 1-5.

COUNTING FUNCTION (With “PCS” or “C” key)

1. Please select 25pcs of samples (or “50”, “75”, “100”) from the objects to be counted, as an example.
2. After opening the scale, place the example on the platform. Then press and hold “PCS” (counting key) for two seconds, and you will see “25” (or “50”, “75”, “100”).
3. Try to press “M” (unit key) and you will see “25”, “50”, “75”, “100” etc. Please select the correct number same as the sample number. Then press “PCS” (counting key) to confirm it.
4. Now you can put the objects that you want to count on the platform and the LCD will show the actual number of the objects.

PRECAUTIONS

• Please check the capacity of your scale. Never load the scale with more than the maximal capacity.
• Avoiding any exposure to extreme heat or cold, your scale works better when operated at normal room temperature. Always allow the scale to acclimate to normal room temperature for at least one hour before use.
• Give your scale sufficient warm up time. Usually 30-60 seconds before calibration to give the internal components a chance to stabilize.
• Keep your scale in a clean environment. Dust, dirt, moisture, vibration, air currents and a close distance to other electronic equipment can all cause an adverse effect on the reliability and accuracy of your scale.
• Handle with care. Gently apply all items to be weighed onto tray top. Although this scale is designed to be quite durable, try to avoid rough treatment as this may permanently damage the internal sensor.
• Avoid shaking, dropping or otherwise shocking the scale. This is a precision instrument and must be handled with extreme care.
• Only operate the scale on a stable, vibration free surface.
• If you don’t use the scale for long time, please take out the batteries, and avoid the batteries acid leaked to corrode the scale.
