IMPORTANT!
YOU MUST ALWAYS DO THE FOLLOWING:
MOUNT THE TRANSDUCER SO THE CABLE IS POINTING DOWN.
PUT THE METER IN TRACK MODE.
1. NEVER USE A TORQUE ARM THAT IS NOT BALANCED ABOUT ZERO. A HIGH PRE-
LOAD,OR AN OPPOSITE DIRECTION PRE-LOAD REDUCES ACCURACY AND IS NOT
INDICATIVE OF REAL APPLICATIONS. A SLIGHT PRE-LOAD MAY, HOWEVER, BE
NECESSARY TO TAKE UP DRIVE TOLERANCES IN THE DIRECTION TO BE TESTED. A 1
OR 2 LB HANGER WEIGHT SHOULD BE SUFFICIENT.
2. ALWAYS APPLY FULL SCALE TORQUE, THREE TIMES, WITH WEIGHTS, IN THE
DIRECTION YOU ARE TESTING PRIOR TO RUNNING AN ACCURACY TEST.
3. AFTER STEP 2 ABOVE, WAIT AT LEAST 30 SECONDS OR FOR THE WEIGHT HANGER
TO STABILIZE. SWINGING HANGERS WILL GIVE AN INCORRECT ZERO READING AND
MAY THROW OFF ACCURACY.
4. AFTER STEP 3 ABOVE PRESS THE ZERO BUTTONS (EVEN IF THE DISPLAY SHOWS
"000.0") DO NOT PRESS THEM AGAIN UNTIL YOU START A COMPLETE NEW TEST
CYCLE (STARTING FROM STEP 1 ABOVE).
5. AFTER STEP 4 ABOVE APPLY 10% LOAD, LET THE HANGER STABILIZE AND CHECK
READING. DO NOT REMOVE THE WEIGHTS WHEN FINISHED CHECKING AT THIS
POINT.
6. AFTER STEP 5 ABOVE APPLY ADDITIONAL WEIGHTS TO THE HANGER TO BRING
THE TORQUE TO 50% OF LOAD AND CHECK READING. DO NOT REMOVE THE
WEIGHTS WHEN FINISHED CHECKING AT THIS POINT.
7. AFTER STEP 6 ABOVE APPLY ADDITIONAL WEIGHTS TO THE HANGER TO BRING
THE TORQUE TO 100% OF LOAD AND CHECK READING.
THE MAJORITY OF ACCURACY PROBLEMS OCCUR DUE TO INCORRECT LOADING
SEQUENCE, ZERO PROCEDURES AND TORQUE ARMS THAT ARE NOT IN BALANCE
WITH A SLIGHT PRE-LOAD IN THE DIRECTION TO BE CHECKED.
