OPERATION

Initial Start-up
Allow the scale to warm up for 15 minutes to stabilize the measured values after switching on.

Switching on/off

• Switch on the indicator by pressing switch. The display will show the scale version and will start after self checking.
• After self checking, the display will be come to normal weighing mode.
• To switched off the scale, press switch again.

Zero

• Environmental conditions can lead to the balance not showing zero in spite of the platform not taking any strain. However, you can set the display of your balance to zero any time by pressing switch and therefore ensure that the weighing starts at zero.

Tare

• The weight of any container can be tared by pressing switch so that with subsequent weighing the net weight of the object being weighed is always displayed.

Taring a container

• Load weight on the platform.
• Press switch. Zero is displayed, and tare is subtracted. NET indicator light will be on.
• Remove weight on the platform. Tared weight is displayed. Only one tare value can be set. Tare weight will be shown with a minus value.

Muti-tare

• Load weight on the platform.
• Press switch. Zero is displayed, and tare is subtracted. NET Indicator light will be on.
• Load another weight on the platform.
• Press switch. Zero is displayed, and tare is subtracted. NET Indicator and stable light will be on.
• Remove weight from the platform. Total tared weight is displayed. Tared weight will be shown with a minus value.

Clearing tare

• To clear the tare value, remove the load from the platform.
• Press switch. Zero is displayed, the NET indicator light and tare weight is cleared.

Accumulation

The scale can be set to accumulate manually by pressing the switch.
Before operation the scale should be stable and returned to zero. Accumulation is available only when the weight is more than 20d.

Accumulation Operation

• Place the weight on the platform.
• Press the switch when the STABLE indicator is illuminated.
• The display will show the total saved value for two seconds and the MR indicator will be illuminated.
• Remove the weight from the pan.
• When the display shows zero and stable then place the next weight on the platform.

Memory Recall

• To recall the memory press switch when the scale has nothing on the platform and the display is zero.
• The display will show the total saved value for two seconds.

Memory Clear

• Press the switch in zero point. The display will show the total saved value.
• Press the switch. All accumulation values will be cleared from the memory and the scale will return back to normal weighing mode.

Counting Mode

The scale can perform a counting procedure once the average weight of the part is known. Proceed by putting on a certain number of the parts to be counted. The balance determines the total weight and divides it by the number of parts. This is called the reference quantity. Counting is then carried out on the basis of the calculated average piece weight.

Enter Counting Mode

• In normal weighing mode, Press the switch to enter the parts counting mode. The PCS indicator will be illuminated and the display will show 0

Counting Mode Operation

• Press the switch to change the parts quantity. The display will show C00000
• Change the parts quantity as you need by using the switch to move the digits to the right and using the switch to change the value.
• Place objects intended for sampling on the platform.
• Press the switch to confirm. The display will show the quantity you set.
• Then add items and the display will update the parts quantity automatically.

Exit Counting Mode

Press the switch to return back to normal weighing mode.

Animal Weighing Mode

This mode is used to weigh a moving object such as an animal.

To enter Animal Weighing Mode

Press and hold switch 2 seconds in normal weighing mode and the scale will enter animal weighing mode. The display will flash ANI-ON and the animal symbol will be illuminated.

Animal Weighing Operation
