What's Included:
- Pocket Scales
- Instruction manual
Operation:
- Place the scale on a horizontal flat surface.
- Press the [ON/OFF] key to turn on the scale.
- Wait until the LCD displays "0.0".
- Put the object(s) to be weighed on the weighing platform.
- Press the [M] key to switch between the weighing units.
- If the display shows "O-Ld", it indicates an overload; remove the excess load immediately to avoid damage.
- If the display shows "---" and the figures fluctuate, the scales are not properly supported on a flat surface.
Functions:
Tare Weighing:
- Turn on the scale as described above.
- Place the "tare item" (e.g., container) on the platform.
- Press the [T] button and wait until "0.0" is displayed.
- Add the "net-weight-item" into the container, and the screen will display the weight.
Counting Function:
- Turn on the scale and wait until the LCD displays "0.0".
- Place a sample amount (25pcs, 50pcs, 60pcs, 75pcs or 100pcs) of the item you wish to weigh and count onto the platform.
- Press and HOLD [PCS] key for 2 seconds; the LCD will display a random number, for example "100" and "PCS" will flash in the corner.
- Press the [M] key to set the correct sample amount of items that you have put onto the platform.
- Briefly press the [PCS] key to confirm the above information; the LCD will now display "PCS" solid in the corner to show that the scale is in counting mode.
- Remove the sample quantity from the platform.
- Now, place any amount of your item(s) on the scale, and the LCD will display a count.
- You can switch between weighing mode and counting mode by pressing the [M] or [PCS] key respectively.
Calibration:
- NOTE: Calibration is not required before initial use but only if "out2" is displayed or at intervals as a check to ensure accuracy.
- Reset the scale by pressing the [ON/OFF] key.
- Wait until the LCD displays "0.0" and then press and HOLD the [M] key for 3 seconds.
- The LCD will display "Zero" followed by the required calibration weight.
- Add the required calibration weight; the display will show "PASS" and return to normal weighing mode.
- Store the calibration weight safely and press [ON/OFF] to turn off the scale. Calibration is complete.
Maintenance Features
Battery Replacement:
- When the LCD display starts to fade, it is necessary to replace the batteries. Measurement may still be made for several hours, although accuracy cannot be guaranteed.
- Slide the battery cover away from the instrument and remove the batteries.
- Replace with new AAA batteries, noting the correct polarity, and refit the cover.
Cleaning the Casing:
- Wipe using a moist cloth or sponge.
