FCC COMPLIANCE STATEMENT This equipment generates uses and can radiate radio frequency and if not installed and used in accordance with the instruction manual, may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment.
CARE AND CLEANING Indicator The indicator contains no user-serviceable parts and maintenance should be limited to an occasional cleaning and battery replacement as required. General Cleaning Instructions • Do not submerge the scale or indicator in water, or pour or spray water directly on them to clean. The scale and indicator are not waterproof and covering them with water will damage them and void the warranty. • Always remove power before cleaning.

8500/8550, 8500KGEU/8550KGEU PORTABLE STRETCHER SCALE TEST PROCEDURE A. EQUIPMENT REQUIRED B. SETUP C. SCALE TRIM ADJUSTMENT D. CALIBRATION E.
A. Equipment Required Scale under test Standard Hand tools Test Weights: Appropriate certified weights to accomplish the linearity tests B. Setup - HI RES MODE (MV2 ONLY, OTHERWISE GO TO STEP C.) 1. Assemble scale. 2. Plug unit into power. 3. For KGEU models, first go to the setup table and Calibrate the scale. Next, return here to the initiate the HI RES mode for the scale trim adjustment. Then recheck the capacity weight and recalibrate if necessary. 4.

E. Final Test 1. Perform Corner Test using 1/4 capacity weights (positions 1-6). Use tolerances listed in the Calibration Table below. 2. Perform Linearity test. Check both ascending and descending. See table below. 3. Install indicator cover (MV1). 4. For kg units calibrated using lb weights, reset the Cap = 300 after calibration. 8500, 8550, 8500KGEU, 8550KGEU Linearity Check Table 8500 / 8550 Applied Weight 0 Tolerance WEIGHT POS 2 5 4 0 *200 lb 199.8 lb To 200.2 lb 1,2,3,4,5,6 400 lb 399.
APPLICATION OF ADHESIVE/ADHESIVE BACKED ITEMS 1. Use a clean cloth or paper towel to clean the surface with alcohol where the adhesive or adhesive backed item is to be applied. 2. After the alcohol has dried, use another clean dry cloth or paper towel to wipe the surface clean of all residue before the adhesive backed item is applied. 3. Apply the adhesive backed item immediately after the surface has dried. Be careful not to touch either the application surface or the adhesive with the bare hand. 4.

PARTS IDENTIFICATION, CONT. 8500 Final Assembly – 0065-0809-0A NOTES: 1. Wire indicator and load cell cables as shown in schematic. Check to make sure that none of the indicator cables, or load cell cable wires are crossed, or touching where they connect to the trim board to avoid a short circuit. Route cables through available holes. 2. Ensure correct wiring occurs before addition of cover plate. 3. Calibrate and set up indicator per Test Procedure section. 4.
