I. OPERATION 1. Press [ON/MEM] key.2. Wait until "0.0" is displayed.3. Put the object(s) on the weighing platform.4. Using the [MODE/CAL] key, you can switch between the weighing units.
II. TARE WEIGHING1. Turn on scale as described above.2. Place the "tare item" (ie. bowl) on the platform.3. Press [TARE] and wait until "0.0" is displayed.4. Add the "net-weight-item".Note: Turning the scale on with the tare item on the weighingplatform achieves the same effect.
IV. COUNTING FEATURE[Display] Elimination of errors Change the batteries. You are overloading the scale. Remove the excess weight immediately to prevent damage to the internal load cell. There was a calibration error. Repeat calibration.
1. To enter parts counting mode, press [CAL/MODE] to scroll through the weighing modes until "C" appears on the display. The minimum sample quantity is 5 and will be displayed as "S=5"
2. Continue to press the [CAL/MODE] key to select the desired parts counting unit: 5, 10, 20, 50 pieces. After "50" is displayed the scale will cycle back to g (grams).
3. With the sample quantity value still displayed on the LCD, place the actual sample quantity on the platform. Allow the sample to stabilize for 3~5 seconds then press [TARE]. The sample quantity is now set.
4. You can now add any number of the item on the scale and a count will be displayed.
V. MEMORY FUNCTION
1. With the balance on, press the [TARE] key to ensure the balance is zeroed.
2. Place an item on the scale and press [ON/MEM] when the display is stable. This action adds the displayed weight into the memory buffer which is normally set to zero. The display will show "0.0" again.
3. Repeat step 2 above as many times as you need, until you are ready to see the cummulative result.
4. To view the cummulative weight, press the [ON/MEM] key. The total will be displayed and the memory buffer will return to zero.
5. Press [TARE] to zero out the balance and the scale is ready for normal weighing again.VI. TROUBLESHOOTINGThe primary reasons for inaccuracy or malfunction are low batteries, incorrect calibration, overload or operating on an unstable surface. Please keep this in mind and maintain and operate your scale properly. This scale is a precise instrument and must be handled with the utmost care and caution.
