VIDEO: GearWrench Electronic Torque Wrenches (Nos. 85076 and 85077)

The GearWrench 3/8" drive 85076 and 1/2" drive 85077 electronic torque wrenches make accurate tightening easy because the flashing visual and beeping audible alerts let you know before you reach the target torque. So, there's less chance of over-torquing fasteners, and the vibrating handle confirms you've reached the torque setting.

Setup is quick and tightening fasteners to the correct torque is easy so you can get more done in less time. Here's how easy it is to use the electronic torque wrenches from GearWrench: 

1. First, press the power button to turn the wrench on the numeric display will appear. It's important you don't apply any torque pressure to the wrench during setup.
2. Select your preferred unit of measurement by scrolling through your choices using the unit button. These wrenches offer five choices: foot-pounds, newton meters or inch-pounds are the most popular. Your choice will stay in the wrench memory until you change it. Now you can set your target torque. 
3. Press the set button scroll up or down to get the right torque then press set again to lock in your choice.
4. Again this number will stay in the wrench memory until you change it.
5. You've selected your unit of measurement and target torque, so now you get to decide how close to the target torque you want the flashing LED and audible beep alerts to start. This is called the target torque alert and there is no correct setting. It depends on your personal preference and working style. For example, if your target torque is 80 foot-pounds and you want the alerts to start when you're halfway there at 40 foot-pounds you simply set the target torque alert to fifty percent. But if you don't want the visual and audible alerts to start until you're much closer to your target torque you might select 25 percent. Then the alerts won't start until you hit 60 foot pounds. Set the target torque alert by first pressing the percent button. Using the up or down arrow keys scroll to the target torque alert you prefer.
6. Then press the percent button again to lock in your choice.
7. Now you can go to work! Here we've set our target torque the 75 foot pounds with the torque alert at 50 percent. As the target torque is approached the visual and audible alerts begin. Once the target has been reached both alerts turn continuous and the handle vibrates. 

The 3/8" and 1/2" drive electronic torque wrenches come with the GearWrench one-year limited warranty and a 90-day calibration guarantee.
