key. The display will show the current High Limit with the left most digit flashing and the HI symbol on to the left of the
display.
To change the value shown use the

After pressing the
key the display will then show the Low Limit, the LO symbol will be on the left side of the display.
Enter the low limit in the same way the high limit was entered.
After pressing the
key the scale will return to weighing with the Check-weighing function enabled.
When a weight is placed on the scale the arrows will show if the weight is above or below the limits and the beeper will sound as your
setting (see detail in section 9).
BOTH LIMITS SET
The display will show OK when the weight is between the limits.
LOW LIMIT SET, HIGH LIMIT is set to zero
The display will show OK when the weight is less than the Low Limit. Above the Low Limit the display will show HIGH.
HIGH LIMIT SET, LOW LIMIT is set to zero
The display will show LOW when the weight is less than the High Limit. Above the High Limit the display will show OK.
BOTH LIMITS SET, LOW IS SET GREATER THAN HIGH
The beeper will never sound and the display will show LOW if the weight is less that the LOW limit, and HIGH if the weight is
greater than the Low Limit.
NOTE:
The weight must be greater than 20 scale divisions for the checkweighing to operate.
To disable the Check-Weighing function enter zero into both limits by pressing the
key when the current limits are shown then
