Krautkramer USM 35X Issue 01, 04/2005 1-9
Introduction
The USM 35X family
Special features
• low weight (2.2 kg including lithium-ion battery) and
compact size
• waterproof instrument case with protection class
IP 66
• long operating time (> 12 hours) by means of lithium-
ion battery with internal and external charging possi-
bility
• handy – equipped with a non-slip, ratcheting prop-up
stand, also used as handle
• rotary knobs for direct adjustment of gain as well as
for changing the currently selected function
• two independant gates for accurate wall thickness
measurements from the workpiece surface up to the
first echo, or between two backwall echoes, including
measurement on coated workpieces with a resolution
of 0.01 mm (up to 100 mm), referred to steel
• magnify gate: spreading of the gate range over the
entire screen width
• 5.7", 1/4 VGA-TFT color display to display the digi-
tized signals (320 × 240 pixels, 115 × 86 mm )
• VGA interface for the connection of an external
monitor
• color display of gates for an easier distinction
• easily recognizable reflection geometry when using
angle-beam probes by the variation of A-scan or
background color at every deflection point
• data memory: 800 data sets, including alphanumeric
description, documentation possibility via a printer
• increased calibration range: up to 9999 mm (steel),
depending on the frequency range
• semiautomatic two point calibration
• pulse repetition frequency variable in ten steps
to avoid phantom echoes when testing large
workpieces
• choice of frequency range for the connected probe
• signal display mode: full-wave rectification, positive
half-wave or negative halv-wave and radio frequency
• display of 4 readings plus 1 reading zoomed in the
A-scan, user-configurable
