Coupling to the 1” Cal Standard (1
st
Point)
Apply a drop of couplant on the transducer and place the transducer in steady
contact with the 1” calibration standard. Be sure that the reading is stable and
the repeatability indicator, in the top left corner of the display, is fully lit and
stable. Also, be sure there is sufficient signal amplitude in order to avoid ‘peak
jumping’ or missing the first cycle.
Adjusting the Gate
1) Press the
MEAS
key once to activate the measure menu items. Press the
MEAS
key multiple times to move right and the
ESC
key multiple times to

RIGHT
arrow keys to move the gate over the waveform
to be measured, as demonstrated in the screen shot above.
Note:
In order to trigger on a signal, the waveform must be inside the
boundaries of the gate.
Calibrating the First Point
1) Press the
MENU
key once to activate the menu items tab. Press the
MENU
key multiple times to tab right and the
ESC
key multiple times to tab left until
the
