Epson USN 52L, USN 52R manual Introduction

USN 52R/USN 52L Introduction

•60 Hz A-scan refresh rate,

•mains power or battery operation (max. 5 hours of operation),

•on-board Data Logger for storage of up to 2,500 thickness readings in a maximum of 99 freely configurable files,

•RS232 interface for data transfer, A-scan displays and reports, or for remote control of the USN 52 R,

•storage of 140 (USN 52R) / 100 (USN 52L) control data sets enabling quick calibration and reproducibil- ity of the test,

•alphanumeric entry of data set names and display of a directory of all data sets,

•frequency ranges from 0.25 - 11 MHz wide band

•echo representation: RF signal, full-wave, positive and negative half-wave,

•optimized probe matching by means of 4 adjustable damping values between 50 and 1000 ohms,

•automatic calibration of the sound velocity and probe delay according to data from 2 calibration echoes (with plausibility check),

•2-stage adjustment of pulse repetition rate in order to avoid phantom echoes,

•indication of amplitude and sound path for flaw testing and thickness measurement,

•DAC for convenient display evaluation according to the reference block method (e.g. ASME code, etc.),

•analog outputs for external control purposes: propor- tional voltage for amplitude and sound path of the echo in the monitor gate,

•A-scan storage, peak freeze and zoom function,

•preview of all stored A-Scans,

•locking function to avoid unintentional alteration of set values,

•magnified display of measured values for easy reading even from longer distances,

•rapid switching between programmable sound velocities, e.g. for longitudinal and transverse waves in steel.
