- Page 2 Safety Warnings Always wear safety glasses when operating this torque meter. Always use the proper range transducer for the application. Over torque may result in damage to the transducer or breakage resulting in personal injury. Under torque may result in an incorrectly tightened fastener that could loosen resulting in failure at a later date.
- Page 3 Introduction The ELORA Electronic Torque Meter is a highly accurate torque analyzer and production tool. Use it as a high end torque calibrator or bring it to the work site to accurately apply torque to fasteners. With the ELORA Electronic Torque Meter you only have to buy one electronic module.

Entering Numbers When a number needs to be entered, a default 000.0 value (or the last value entered) will be shown. The digit that can be changed will blink. Press the increase key to increase the value of the blinking digit. Press the next key to go to the next digit. -
Page 15: Torque Sensors (Transducers) And Overload
Torque Sensors and OVERLOAD Torque transducers are designed to give years of reliable operation if treated properly. Torque transducers are sensitive electro-mechanical measurement devices and should be handled with care. Never over-torque a transducer beyond its usable range. It is good practice, when possible, to select a transducer that is at least 25% greater in range than the expected torque it will apply. -
Page 16: Transducer Mounting Positions
Transducer mounting positions for bench top style torque transducers: Warning! Always make sure the bench is strong enough and will not tip wen applying torque Bolting the bench to the ground may be necessary on higher range transducers. 3” bolt circle for 3/8 inch screws 2.175”... -
Page 17: Checking For Accuracy
Checking for accuracy The Torque Meter and torque transducers are factory calibrated and should be checked on a regular basis. We recommend that, provided the transducers are used according to this manual, they be re-certified yearly. Since the frequency of use, among other factors, may affect the calibration, the user must determine the best calibration interval. - Page 18 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.

Page 19: Calibrating And Bypassing The Smart Transducer Calibration Data
You can not change the information on the smart chip within the transducer. If the values on the chip need to be changed then one of two things MAY have happened: 1. The torque arm system, or the procedure, is introducing errors that when added are creating an out of tolerance situation (SEE ACCURACY CHECKING ABOVE).. - Page 20 6. Set the estimated clockwise (cw) Mv/v (if known, use 2.000 if not known). Press Save. 7. Set the Counterclockwise (ccw) Mv/v (if known, use 2.000 of not known). Press Save. 8. The display will now show “calc” (more on “calc” later). Press the next key until the unit shows “cert”.

Page 21: Selecting Custom Transducers
“Hyper terminal” that comes standard with Windows or any third party data logging software. The ELORA col that the torque meter sends data is as follows: RS232C, 4800, 8, 1, n Refer to your computer or printer operation manual for a description of these settings. -
Page 22: Battery And Power
The torque meter uses either a common 9 volt battery (gives longest life) or a rechargeable 9 volt battery (supplied standard for convenience). Battery life depends significantly on the type of battery used. Non-rechargeable lithium ion 9-volt batteries may last up to 40 hours. Common alkaline batteries may last up to 20 hours. -
Page 23: Specifications
Memory: Up to 1,350 torque data. Includes data number, torque value and units. Communication: Direct to serial computer or printer. ELORA col: RS232C 4800 BPS, 8, 1, n. Communication cable and adapter supplied standard. Operating Modes: Track, Peak and First Peak for calibration of Micrometer (clicking) torque wrenches.
