Electronic torque wrench has the fastest sampling of torque measurements and update of displayed torque on the LCD of any wrench on the market. Of course, just like when you decide to buy something; you will want to get the best deals on it. In this case, Jetco electronic torque wrenches are considered to be very accurate, durable, easy to use, and easy to learn.
These wrenches are known as the first true production of the electronic torque wrench. The good thing when deciding to deal with this Jetco electronic torque wrench is that you will not need to have an engineering degree in order to be able to operate this wrench, just turn it on and go to work!
In actual fact, the Electronic Torque Meter is considered to be a pretty neat electronic torque wrench. It consists of a 103mm (4″) long, 292 gram (10.25 oz.) sensor unit with a 1/2″ female square drive socket on one end, and a male 1/2″ square drive on the other.
The sensor unit has a 132cm (52″) long and 3mm (1/4″) diameter cable coming out of one end. The cable plugs into an electronic box that measures about 162mm long by 90mm wide and by 40mm thick (6-3/8″ x 3-1/2″x 1-1/2″), including it’s red soft plastic case.
The electronic box weighs 398 grams (14 oz.), and it has a fold-out arm that allows you to stand it upright. And a fold-out tab on top with a hole in it would be very useful for hanging up nearby when in use. Also, the sensor takes one 9v battery.
Moreover, the Electronic Torque Meter has a couple of unique features. This kind of electronic torque wrench can be set to “Peak Mode”, which displays and holds the highest torque reading in any one application. This can be quite useful if you are working in a location where you cannot read the meter.
The display can be cleared by pressing a couple of buttons on the box in order to get another reading. This kind of electronic torque wrench will also turn itself off after a short time if not being used, and if the wire becomes unconnected from the box when in use, you will also get a warning tone.
The most useful mode of this electronic torque wrench is probably the “Target Mode”, which allows you to pre-set a specific torque reading. As you apply torque, the unit beeps. As you get closer to the pre-set torque value, the beeping frequency increases and if you exceed the pre-set value by >5%, you will hear a continuous tone.
Another good thing that you can get from this electronic torque wrench is that you can get some codes for things like low battery, zero over limit, circuit failure, and poor sensor connection. But the biggest problem with the Electronic Torque Meter is that its way too long to use in many motorcycle applications.
After you add up the length of the sensor unit itself, a 1/2″ drive ratchet or breaker bar, a 1/2″ to 3/8″ conversion socket, and whatever size final socket you need to torque the nut or bolt, you end up with what is virtually a 6″ long socket. This is just too long to fit into most of the cramped areas under a frame or bodywork of a motorcycle.
