For Use with Adjustable Automatic Donor Scales

Inspection and Testing:

The following visual and functional tests must be performed daily prior to use:

1. Visual:
   Refer to Figure 1 for visual inspection.
   The blood donor scale support post must be inspected to check if:
   a. The bubble in moving freely in the level eye.
   b. If there is resistance in the movement of the front and top adjusting screws.
   c. The locating pins are broken.
   d. Bent, or missing parts.
   Note: If any of the conditions listed above are observed, do not use the blood donor scale support post.
   
2. Functional:
   If the blood donor scale support post is not already installed, perform installation as instructed in the "Installation" section below. The blood donor scale support post must be functionally tested as follows:
   a. Slowly tilt the blood donor scale support post from the left to right in the horizontal
   direction while observing the bubble is moving freely in the level eye.
   b. Slowly adjust the front adjusting screw inwards and outwards, ensuring that there is no resistance
   on the movement front adjusting screw.
   c. Slowly adjust the top adjusting screw inwards and outwards, ensuring that there is no resistance on
   the movement top adjusting screw.
   Note: If the blood donor scale support post fails the functional test, do not use the blood donor scale
   support post.
   

Installation:

1. Insert the blood donor scale support post into the adaptor plate on the donor bed
2. Check for free movement of the blood donor scale support post and ensure that the blood donor
   scale support post is well anchored into the adaptor plate on the donor bed.
3. The blood donor scale support post must be level to function properly. Check level periodically.
   If blood donor scale support post is jolted, disturbed or moved to a different location, ensure that it
   is level before using.

Instructions for Use:

1. Slowly adjust the front and top adjusting screws until the bubble floats exactly between the
   black circle marked on the levels glass window.
   a. If bubble is more to the front, or rear of level window - adjust the front adjusting screw.
   b. If bubble is more to the left, or right of level window - adjust the top adjusting screw
2. Level is achieved when the bubble floats exactly between the black circle marked on the levels
   glass window. If the blood donor scale support post fails this check, repeat step 1.

Maintenance:

1. Do not lubricate or perform any repairs on the blood donor scale support post.
2. Clean blood donor scale support post on as-need basis only, using 10% bleach and 90% tap, distilled or deionized water mixture.
