Need help?Do you have a question about the CDI computorq 3 and is the answer not in the manual?
Over-torquing, out-of-calibration angle wrench, or broken tools can cause injury or breakage.
All users and bystanders must wear eye protection, use rated components, and follow safety procedures.
Avoid operating wrench when powered off, pressing keys during torque application, or using it to loosen fasteners.
Includes avoiding extensions on handles, engaging the switch correctly, and verifying capacity.
Electrical shock can cause injury; plastic handle is not insulated. Do not use on live circuits.
Service, repair, and calibration must be performed by CDI Torque Products only.
The internal mechanism is permanently lubricated; do not attempt to lubricate it.
Wipe with a damp cloth; never use solvents, thinners, or immerse in liquids.
Store wrench in protective tube at its lowest torque setting.
Custom LCD display shows units, readings, and a 10-segment bar graph.
Use UP/DOWN keys to scroll to desired target torque value (10%-100% of full scale).
Display shows actual applied value with 0.20 second update rate while torque is applied.
LEDs and tones indicate torque levels: yellow (-10%), green (target), red (+10%).
Display holds and flashes peak torque reading for 10 seconds after release.
Rapid pulsing tone and display lock ('----') indicate torque beyond 125% of full scale.
Automatic self-calibration check and re-zero upon power on; manual re-zeroing possible.
Wrench returns to last unit and torque setting selected upon power on.
Uses two CR123 lithium cells for over 80 hours of continuous operation.
Press and hold ON/ZERO to power on; press and hold for 5 seconds to power off.
Wrench powers off automatically after 2 minutes of non-usage to conserve battery.
Steps for powering on, selecting units, and pre-selecting desired torque using UP/DOWN keys.
Grasp handle centered for highest accuracy; avoid grasping above or below.
Torque using pulling motion, stop at green LED/tone, adjust for red LED over-torque.
Calculate adjusted torque setting when using adapters/extensions to maintain accuracy.
Formula provided to calculate new torque output based on adapter/extension length.
Do not exceed 15 degrees offset with universals; avoid long flex-drive extensions.
LCD features: display capacity, setting, tracking, peak hold, and accuracy details.
Details on drive size, length, weight for specific part numbers.
Specifies temperature and humidity limits for operation and storage.
Two CR123 lithium cells provide 80+ hours; replace when 'bAtt' is shown.
Contact CDI Torque Products for calibration services.
Precision test bars, certified weights, or accurate torque source needed for calibration.
Display showing 'Erro' indicates wrench damage; return for repair.
Remove battery when storing for extended periods.
Formula TW = (TA x L) / (L + A) to calculate new torque output with extensions.
Adapter/extension length, wrench length, and hand position affect accuracy.
