American Weigh Scales (AWS) Mini-Pro-30 - Manual (Page 5)

VI. Auto-Off Feature
This scale has an Auto-Off feature that can help battery life
by turning the scale off when not in use for a certain amount
of time (1-9 minutes). To change the Auto-Off timer, press the
“Fn” button three times. The scale will show the current Auto-
Off setting (OFF, 60, 120, 180, 240, 300, 360, 420, 480, or 540)
Press the “Unit” button to cycle through until you find the de-
sired timer duration (in seconds). Press “Tare” to confirm your
selection.
VII. Calibration
If the scale is not performing properly or is displaying incor-
rect weight, you may need to recalibrate the scale. Typically,
the Standard Calibration method is sufficient for the average
user to recalibrate their scale. Advanced calibration is already
performed at the factory and should not be attempted unless
you are still having problems. Before starting calibration, insure
that the area you are working in is free of drafts, vibration, and
all radio-wave emitting devices (cordless phones etc).
• Standard Calibration:
You will need a 10 gram weight to perform calibration. Press
the “Fn” button one time, “SCALE” will be displayed on the
LCD; Press the “Tare” button to continue. The scale will
display 10.000 . Press “Tare” once more. When the scale will
flash “10.000” on the display, place your 10g calibration weight
onto the weighing surface. In a few seconds, the display will
stop flashing, and return to normal weighing. Calibration is
complete!
