Problem

What to Do or Check

Person or object other than that being

weighed is touching the scale.

Verify that there is nothing caught in or

interfering with the seat.

Verify scale calibration is correct. If

problem persists, recalibrate the scale.

Make sure that the scale is stabilizing

(Motion annunciator is off). After pressing

the Zero button, the scale should zero as

soon as it becomes stable.

Verify the scale calibration with an

accurate test weight. If the readings are

not correct, recalibrate.

Be sure the chair is on a flat surface and

all four wheels are touching the floor.

Check for air currents and/or vibration

around the scale.

Press the Zero button to turn on the

indicator.

Check that new batteries are installed

properly in the battery tray.

If using an AC adapter, confirm that it is

firmly plugged into a functioning wall

outlet.

Verify the connector at the rear of the

indicator is properly installed.
