High Output Transducer (H/O)

Torque transducer with no coding links but internal pre-amplifier giving an output signal level of typically 1 or 2 volts.

Horizontal Sampling

Collection of data by round, taking one reading for each characteristic in turn.

Industry Standard Transducer (I/S)

Type of transducer, with no pre-amplifier or coding links, but with the exact rated torque, marked on the body.

Master Round A sequence of up to five rounds. It is used to allow a collection sequence, which is part vertical, part horizontal.

Max Torque Value

Upper tolerance level of any reading. This can equal but not exceed the torque rating of the transducer to be used.

Min Torque Value

Lower tolerance level of any reading.

No. of Sub Groups

Number used to allocate memory space in ETA, for a particular characteris- tic. May be set in the range of 1 to 99.

Round	A sequence of characteristics to be collected either horizontally or vertically.
	Each round has a name of up to 14 characters.
Sample	Individual torque reading.

Standard Deviation σ

Is a measure of the variation of the samples of a statistical group. If a group of ‘n’ values has a mean of ‘x’ then its standard deviation is given by:
