Operating Instructions
Zero Balance Adjustment
The scale should be checked periodically, particularly when moved, by following the instructions below:
1. Make certain scale is on a hard, level surface. Step on and off scale a few times in order to align all internal
parts.
2. Place both poise weights on zero (see Fig 3). The beam pointer should float gently up and down and not touch
the top or bottom of the trig-loop.
Note: If the beam pointer is not moving equally centered in the trig-loop opening, turn balance ball screw (See
figure 3) to correct.
Conversion (lb to kg / kg to lb)
1. Rotate both the upper and lower poise bars with a gentle twist of the wrist (Figure 4) to the selected unit of
measure.
2. Check poise bars to make sure both match in color. For easy identification, pound poise bars have chrome
graduations on a black background; kilogram poise bars have black graduations on a chrome background.
Weighing Instructions
1. Set the large and small poises to indicate your approximate weight.
2. Set on the scales. Continue to adjust the small poise until the pointer is centered.
NOTE: It is not necessary for you to wait for the pointer to stop moving in order to read your correct weight. As
long as the pointer is moving equally in the trig-loop opening, the pointer would eventually come to rest in the
center of the opening. Even when the pointer is not perfectly centered, as long as it is moving, you are within
one quarter pound of your correct weight.
3. Add the indicated reading of small poise to the indicated reading of the large poise. The total is your weight.
Weighing Hints
1. Weigh yourself at approximately the same time each day. The foods you eat, liquids you drink and your level of
activity will cause your weight to vary.
2. For more realistic results, weigh yourself without clothing. The average weight of clothing, including shoes, is
about 0.90-2.26kgs.(2-5 lbs.) for women and 2.26-3.62kgs (5-8 lbs.) for men.
Maintaining The Scale
1. The baked enamel finish, lens and mat can be cleaned with a mild soap and damp soft cloth. DO NOT USE
ABRASIVE OR STRONG CHEMICAL CLEANERS.
2. All bearings and working parts are permanently lubricated. DO NOT USE OIL OR LUBRICANTS.
3. If your scale fails to work properly, do not attempt to dismantle it. This will void your warranty. See warranty
information for instructions on having your scale serviced.
Maintenance
Clean scale routinely with anti-bacterial soap.
