Romanization of Greek Greek numerals which employed the entire alphabet, including the nonstandard letters digamma, stigma, or sigma-tau (placed between epsilon and zeta), koppa (placed between pi and rho), and sampi (placed after omega). As revised in 2001, ELOT 743 provides for the uncommon characters to be given (in Greek) as $ for stigma, + for koppa, and / for sampi. These symbols are not given lower-case equivalents. When used as numbers, the letters are used in combination with the upper "keraia" numeral sign ⟨ʹ⟩ to denote numbers from 1 to 900 and in combination with the lower "keraia" ⟨͵⟩ to denote multiples
Torque tester plugged into an algorithm to calculate the force applied to the transducer. There are several styles available for torque transducers. Rotary, stationary (reaction), and inline are used for different calibration and audit purposes. A key component of modern torque testers is the digital display. A digital display is used to measure the output signal from the transducer and calculates that reading into a torque value that is displayed on screen. In most cases the display and transducer are contained together inside a housing. This is known as a “Desktop Torque Tester”. External rotary and stationary transducers can be used with
