Key Functions Each of the keys shown in Figure is explained below. Figure 2: B 120 keypad Used for keyboard entry of piece weight, sample size, and upper and lower limit settings.

Scale Operation This section covers the various scale operations, such as weighing, counting, accumulation, etc. Simple Weighing Turn the scale on and zero the display, if necessary, by pressing the Zero key. Be sure the scale is displaying weight in your preferred unit of measure.
ZERO key. A counting scale needs a minimum amount of weight to calculate counts with accuracy. Salter Brecknell recommends the sample weight be a minimum of 0.1% of scale capacity. The sample weight is the total weight of your sample items.
Press the Enter key to accept the keyed in number. (If you make an error in keying in the number, press the Clear key to clear the count in the COUNT window and re-key the correct number.)… The scale calculates the weight of each piece (the piece weight) and displays the count in the COUNT window.
Place the items to be counted on the scale… The total weight, piece weight and count of the items will be shown in the three display windows respectively. Remove the items from the scale and repeat steps 4 and 5 to count items of the same piece weight.
Remove the items from the scale and repeat steps 7 and 8 to weigh the next batch of items. Counting with upper and lower limits can be done while using a tare. After you have set the piece weight (step 2), place the item to be tared on the scale, press the Tare key and continue with counting as described in step 3.

The scale will not accumulate more than 999,999 times, or show an accumulated quantity over 16,777,215. If this occurs the display will show ------. This means over range. When the accumulated quantity is more than the six digit display can show (999999), it will be displayed by alternately flashing the first four digits H XXXX) then the second four digits (L XXXX).

Access to the calibration switch may be sealed with a lead-wire combination on the bottom of the scale. Prior to removing the lead seal, check to see if the test switch is in the correct position by following step 1 below. If you are not allowed access, remove the lead-wire seal.
Press the Enter key to confirm the zero point again. The scale goes through the start up routine and ends in normal weighing mode. If there is any error in the calibration, the scale will show CAL. Err. The scale will try to return to the previous step. If you have problems, press the On/Off key to exit the calibration mode and try the procedure again.
Setting the Auto-Off Timer You can set an auto-off timer so that the scale will power down automatically after a period of inactivity. This functions only when the scale is powered by the battery. From normal mode, press and hold the On/Off and Accu keys at the same time until the scale beeps…...
