The Series 400 Amplifier
The Series 400 Amplifier is a sophisticated yet easy to useinstrument with a modular surface texture program. All models feature a vacuum fluorescent display and sealed membrane keypad. An RS-232 commun-
ication port is stan-dard (RS-485 optional), along with a remote start switch port and lockout key switch. Battery power is included
on all models with the graphic plotter, and is optional on all other models.
Operation is at once simple, sophisticated and secure. The instrument is configured by an easy-to-use set-up menu. The user selects the proper settings for the cutoff, stroke length, standard 2RC and Gaussian filters (Rk filter optional), parameter functions, serial port and plotter operation. Set the exact stroke length required or use the standard 5-cutoffs. After setting, the program-ming can be secured by a turn of the lockout key, which prevents inadvertent changes. Once configured, the system operates by pressing the Start Button or through use of an optional remote start switch.

Piloters/Motor Drives
The Skid-Referenced Piloter Skid-referenced systems are designedto measure normal I.D., O.D., and flat surfaces. The skid-referenced motor
drive (piloter) contains a motor which moves the linkarm with the tracer
across the surface to besampled. The tracers have skidpads which establish a reference line. The transducer translates the vertical motion
of the diamond tip stylus inrelation to the reference line. The piloter traverses at a speed of 0.1in/sec (2.54 mm/sec) for the travel length specified and can be set toacquire data in either direction. Our patented Lite-Touch Linkarm pro-tects the tracer and surface from inadvertent damage and comes stan-dard with each system, unless otherwise specified.

The Skidless Piloter
The skidless motor drive has an internal reference in the drive unit. Skidles instruments of the 400 Series are designed to evaluate small, difficult-to-
reach areas that are not accessible by skid-type tracers. The motor drive is mounted on a granite base to minimize vibration and to provide a level,
stable surface for locating the workpiece. For more precise measurement setup, the stroke length can be set to the proper distance for the
surface being measured. This is ideally suited for short stroke requirements such as grooves. This drive may also be programmed to acquire data in either direction.

The Rotary Piloter
The rotary piloter is designed to measure inside and outside diameters of parts such as balls, ball studs, and extruded tubing. The part is rotated across a stationary tracer, through an arc perpendicular to the lay. The drive, with proper tooling, will trace parts with a range from 6.35 mm
to 63.5 mm (0.250 in to 2.500 in) inner or outer diameter. The amplifier will automatically adjust the speed of the rotary piloter, based upon the diameter of the measurement area, to attain a constant speed of 0.1 in/sec (2.54 mm/sec). The piloter is able to take readings in clock-wise or counterclockwise directions. It is easy to use, and can be changed from one part to another in seconds.
