TAKING
MEASUREMENTS
Using the Probe
The probe face is split into two halves: one
half transmits ultrasonic sound waves and the
other half, separated across the centre by a
barrier, receives any reflected signals.
The probe measures the thickness of the
material directly beneath the probe face.
The accuracy of the measurements depend
on good contact with the target material. In
particular, you must ensure that there are no
air gaps or pockets between the material and
the probe face. To achieve a good contact,
apply a droplet of the couplant gel to the
target area and press the probe firmly onto it.
Continue to apply gentle downward pressure
to the probe during the measurements.
Sometimes it can be difficult to obtain good
contact with the target material. Be aware
that layers of paint or rust can interfere with
the transmission of the ultrasound.

Measurement Modes
The UT5000 supports two types of
measurement:
Single Measurement Mode
The gauge stores a single spot thickness.
This is important when inspecting pipeline
thickness in a specific location. You can
configure single mode measurements to
include up to four consecutive Txpulse
measurements using the Multi-Echo setting
(see page 13). The default is one Txpulse
measurement.
Continuous Measurement
(Corrosion) Mode
In this mode, the gauge continues to take
measurements at the specified pulse
Frequency until the STOP key is pressed. The
UT5000 averages all valid measurements
while in this mode storing maximum, minimum
and average values.
Use this mode for basic corrosion inspection:
move the probe slowly over a 100mm square
area and monitor the maximum and minimum
thickness in the inspected area, along with
the average thickness measured.

Setting the Mode
The pulse frequency determines the rate of
repeated measurements. To change the pulse
frequency:
Press the FREQ key, or Press the SETUP
key. Use the arrow keys to highlight Pulse
Frequency, then press the SEL key.
For single measurements, choose Single shot.
For continuous measurements, choose from
the following options: 1, 2, 3, 4, 5, 6, 7 or 8 Hz.
Measurements will be taken continuously at
the selected rate and continue until the STOP
key is pressed.
