USM 36

VOLTAGE (pulser voltage)

You can use the function VOLTAGE to set the pulser
voltage.
The following settings are possible:
● HIGH – high voltage
● LOW – low voltage
The setting HIGH is recommended for all tests in which
maximum sensitivity is important, e.g. for the detection
of small flaws. Choose the setting LOW for broadband
probes or if narrow echoes are required (better lateral
resolution).
Square-wave pulser
If your USM 36 is equipped with a square-wave pulser
(option) and if the square-wave pulser is chosen as
pulser type (see Section Selecting the pulser type,
page 5-75), then you can set the pulser voltage within
the range of 120 ... 300 V in steps of 10 V. Instead of
the function ENERGY, the function WIDTH is then avail-
able.
