Clockwise Calibration
1.
Once display value (torque source code) is stable,
press and release
[M]
. Display will show a calibration
torque value (in N-m ) that needs to be applied in a
CLOCKWISE direction.
2.
With wrench still attached to torque tester, apply
CLOCKWISE torque to wrench (per the N-m value
provided by the display). Ensure torque you are
applying is within 0.5% of specified value while
viewing readout on torque tester.
Example: 80 N-m X 0.005 = 0.4 N-m.
Torque applied should be:
≥
79.06 N-m but
≤
80.04 N-m].
3.
Press
[M]
to set torque value into memory. Display will
read
C - - F
for 1 second
[indicating wrench is now
going to enter Counter-Clockwise Calibration)
. Display
will return to source code.
4.
Release torque. Ensure display returns to zero. Adjust
wrench head for counter-clockwise direction.
Counterclockwise Calibration
1.
When display value (torque source code) is stable,
screen will show a negative (-) calibration torque
value that needs be applied in counter-clockwise
direction
2.
With wrench still attached to torque tester, apply
torque to specified value, and ensure reading is
within 0.5% of applied torque while viewing readout
on torque tester.
3.
Press
[M]
to set calibrated reading into memory.
Display will show “good” once calibration is
performed.
4.
Display will show
8888
and will restart and enter
Measuring Mode within 5 seconds.
Reset to Factory Calibration
1.
On Measuring Mode, press and hold
[
]
and
[
]
at same time.
2.
When display shows
- - - -
release both keys.
3.
Wrench will restart and factory settings will be
restored.
Note: Resetting to “factory calibration” does not guarantee accurate torque
potential (calibration with a torque tester is needed).
ROUTINE MAINTENANCE
Cleaning
- Always turn wrench off before cleaning.
Use only a damp cloth for cleaning (no liquid or aerosol
cleaners, or any organic solvent).
STORAGE
•
After each use, place wrench in storage case and store
in a cool, dry place.
•
Do not store wrench in areas that are dusty, sandy, wet,
humid or near any heat source.
•
Do not leave wrench in areas subject to high
temperatures.
•
Always keep wrench dry. Water or other liquids will
damage internal electronic components.
Batteries
- If wrench will not be used for an extended
time, remove batteries.
OPERATING THE BTLDTW
1. For best results and to prevent jaw wrench from
slipping off a fitting, PULL wrench (
Don’t PUSH
).
“Pulling” means putting the fixed jaw on far side of
nut from your body. Pull wrench handle in clockwise
direction.
2. Ensure your target torque value is indicated in
Display A
.
3. Grip wrench handle and pull wrench with quick
(avoid jerky) movements.
4. In either Peak or Track Mode, green LED will flash
when torque applied is 50% to 98% of desired
programmed torque value (
Display A
) .
5. When approaching programmed value (± 5N-m),
beeper will sound.
6. When within 2% of programmed value, red LED
turns on.
7. When achieving programmed value (± 2 N-m ),
beeper will emit a quicker sequence.
8. If 2% over programmed torque value, beeper will
sound continuously, green LED will turn on and
handle will vibrate continuously.
[If you hear a
continuous tone, stop pulling immediately,
especially if target torque is low].
NOTE: “----” will show in Display B if applied torque exceeds 100% of
Measurement Range (Specifications Table)
CALIBRATION
General
1. Periodic recalibration is required so wrench applies
accurate torque.
2. Re-verify calibration if wrench has been dropped.
3. For calibration, ship wrench to your local CPS office
or have it calibrated by a qualified laboratory of your
choice.
Procedure:
1. Install torque wrench on a calibrated torque tester
(with N.I.S.T. traceability) having a dial or digital
readout and showing N-M units.
2. CAUTION: Always calibrate wrench using N-m
(Newton Meter) units only.
3. When calibrating or checking wrench for accuracy,
apply a load (either clockwise or counter-clockwise
OK) to center of handle.
Starting Procedure:
1. With display in OFF Position, press and hold
[M]
and
simultaneously until display shows
CALI
.
Note: During this time, wrench will be in factory
supplied Auto-Off setting for 15 seconds (without any
operation). If desired, press
to quit calibration mode
.
2.
Within 15 seconds and NO torque applied, press and
release
[

and
[
