Taking a Weight Measurement
1.Once the chair weight has been zeroed out and the display reads “0,” have the patient sit on the chair.
2.The moving dashes will lock in and display the patient’s actual weight.
3.Weight measurement should automatically be displayed on the control panel box console.
•Measurement automatically defaults to pounds. If kilograms are required, push the Kilos switch.
•If a reweigh is required, depress the Zero switch.
4.Excessive movement may prevent a repeatable reading. In this case, a series of moving dashes continues to appear on the console rather than a weight reading. If moving dashes persist, activate the “Average Lock” by depressing the appropriate Pounds or Kilos switch to obtain an average reading of the patient’s weight.
Note: This reading is now an average of weights that the computer calculates.
5.After weight measurement is obtained and recorded, have the patient stand up off the chair and step away from the scale.
6.Depress the On/Off switch to turn the scale off.
CARE AND MAINTENANCE
Proper care and cleaning of all Tanita Corporation scales and accessories is essential to ensure a long life of accurate and effective operation. In addition to routine cleaning, include a regular check of all structural apparatus to ensure stability.
Cleaning
Disconnect scale from 120 VAC before cleaning.
1.All external surfaces can be wiped clean with a damp cloth. Mild soap and water solution may be used. Wipe unit dry with a clean, soft cloth.
2.DO NOT immerse control panel box into cleaning or other liquid solutions.
3.DO NOT use isopropyl alcohol or other solutions to clean surface of control panel box.
4.Check the overall appearance of the whole scale for any obvious damage, wear and tear. Inspect the AC cord and adapter for cord cracking or fraying or for broken or bent prongs.
Calibration
Note: Your scale has been accurately calibrated at the factory. However, there is always a possibility that the calibration changed due to jarring during shipping. The following procedure should be followed to check and/or correct any error in calibration.
1.Depress On/Off switch on scale and wait for a display of “0.”
2.Place an accurately known weight on the platform.
3.If display is other than known weight, then the scale is out of calibration.
4.Remove the upper 2 screws from each side of the control panel. Slightly loosen the bottom 2 screws on each side, but do not remove. Lift off the top portion of the head. Be careful, since it is attached to the bottom portion with a ribbon cable. You will see 2 small adjustment screws toward the front of the control board. The left metal screw is for coarse adjustments; it adjusts for large errors. The right plastic screw is for fine adjustments; it adjusts small errors.
5.Turn the metal coarse calibration screw in small increments, CLOCKWISE to increase weight or COUNTERCLOCKWISE to decrease weight. In most cases, this is the only adjustment needed.
6.If necessary, make adjustments with the plastic fine adjustment screw (right). CLOCKWISE to decrease weight; COUNTERCLOCKWISE to increase weight.
7.Remove weight and depress Zero switch. Wait for a display reading of “0.” Again add known weight to platform. If reading is correct, no further adjustments are necessary. If reading is incorrect, repeat steps 5 and 6 until correct reading is obtained.
NOTE: The Top Knob is for fine adjustment and the Bottom Knob is for coarse adjustment. The fine adjustment knob works opposite of the coarse adjustment
