Epson USN 52L, USN 52R MTL VEL Setting the sound velocity, DELAY Setting the delay, MTL VEL Setting the sound velocity, DELAY Setting the delay

Krautkramer USN 52R/USN 52L Issue 05, 02/00 5-5
H Note:
The setting is limited by the set sound velocity.
The measurement units for all settings – mm or inches
– can be selected in the second operating level.
MTL VEL Setting the sound velocity
In this function you enter the test object’s sound veloc-
ity as a reference value. You have two possibilities:
Coarse: switch between the two preset values, e.g.
3353 m/s or 5918 m/s.
Fine: set a value between 1000 m/s and 9999 m/s. The
name of the function appears in small letters (mtl vel)
H Note:
You can select the two values for the coarse setting in
the second operating level.
Operation:
– Press M to change the displayed value. The set
value is displayed in the MTL VEL function.
– Coarse/Fine change-over: Simultaneously press N
and O in MTL VEL.
DELAY Setting the delay
In this function the timing of the sweep start is ad-
justed.
Operation:
– Set a value between -20 µs and 999 µs (range
dependent) in steps of 0.008 µs with M.
– Reset delay to 0.000 µs: simultaneously press N
and O in DELAY.
H Note:
In order to take the probe delay into account, you must
calibrate the probe zero point with ZERO in the function
group S-CAL.
