To set a new target torque
To recall the last cleared torque value
To save a torque value to memory
To view the attached transducer information
(When % is the default limits mode)
1. Press and hold the limits key for 1 second.
(The current target torque shows with the first digit
blinking).
2. Use the increase and next key(s) to set the new target
torque (see “entering numbers” below).
3. Press the save key to accept the new target torque.
Note:
You will see the new target torque displayed in the
secondary set of digits when the limits mode is on. This
value will remain, even after turning the unit off, until you
either change the units of measure or plug in a new
transducer.
1. Press the recall key.
2. Press the clear key when finished viewing and return to
operation.
You can press the save key to save the recalled torque
value before pressing the clear key. This allows you to
recall and save a value that may have been accidentally
cleared prior to saving.
1. Press the save key to save the displayed torque value to
memory.
If you press the save key when zero is displayed
you will store the zero value in memory.
1. Press the transducer keys.
2. Press clear when finished viewing the data.
Note:
The range is in the upper right digits.

weights and this will show on the meter (yes the meter is that sensitive), resulting in a
possible out of tolerance condition.
Procedure for checking accuracy
Transducers are calibrated to within .5% (bench type) or 1% extension type
IV +/- .1 at the factory. If you require greater accuracy you can bypass the
smart chip in the transducer and perform a manual calibration on
transducers. This will account for variations in torque arm calibration
systems.
IMPORTANT!
YOU
ALWAYS DO THE FOLLOWING:
MOUNT THE TRANSDUCER SO THE CABLE IS POINTING DOWN.
PUT THE METER IN 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 (
) 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.
.
6. AFTER STEP 5 ABOVE APPLY 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.
AFTER STEP 6 ABOVE APPLY TO THE HANGER
TO BRING THE TORQUE TO 100% OF LOAD AND CHECK READING.
THE MAJORITY OF ACCURACY PROBLEMS OCCUR DUE TO INCORRECT
