5. TAKING MEASUREMENTS (continued)

SELECTING MATERIAL VELOCITY

To carry out an accurate measurement, it is important that you provide the UT5000 with

the correct velocity of sound in the medium to be measured. The UT5000 contains a table

of values for the most common materials. For more unusual materials, you may need to

enter the velocity manually.

To change the current material velocity, press the VEL key on the main display.

Use the UP or DOWN keys to choose from the following options:

Material User Defined

Material From List

Having made your choice, press the SEL button to continue.

Material From List

This option allows you to select a velocity from the UT5000's internal table of predefined

materials (see page 10). You can add materials to the velocity data table using the host

system (UT5000 Mini-App).

To select a new material, use the arrow keys to highlight the required material, then press

the SEL key. The new material and velocity replaces the current selection and, until the

material is changed, all measurements are calculated using the user-defined velocity value.

Material User Defined

Use this option to enter material velocity data.

CAUTION! For user defined data, you are overriding any safety checks within the gauge. If

you attempt to override a preloaded material velocity value, the UT5000 prompts you to

confirm any changes: "Material velocity data mismatch, continue YES/NO".

To define a new material:

1. Select UD Material Text.

2. Enter the name of the material you want to define:

Use the arrow keys to highlight the required character, then press the SEL key.

Repeat this procedure until you have entered the full text.

3. Use the arrow keys to highlight ACCEPT, then press the SEL key.

4. Select UD Material Velocity.

5. Enter the velocity for the material:

Use the arrow keys to highlight the required digit, then press the SEL key.

Repeat this procedure until you have entered the full value.

6. Use the arrow keys to highlight ACCEPT, then press the SEL key.

The new material and velocity replaces the current selection and, until the material is

changed, all measurements are calculated using the user-defined velocity value.

TAKING A MEASUREMENT

Before you take a measurement check that you have:

Fitted the probe (see page 5)

Applied couplant to the target area (see page 8).

Selected the required measurement mode (see page 9).

Chosen the correct material velocity (see page 10).

Zeroed/calibrated the gauge (see page 5).

To take the measurement:

1. If an RFID tag applies to the target area, press the SCAN button. The unit must be

within 5cm of the tag for reliable detection. If a tag is detected, all subsequent

measurements will be associated with the tag. If you have set up the tag with

material and alarm settings, these are displayed by the UT5000.

2. Press the probe onto the target area, attempting to exclude all air at the contact

point.

3. Holding the probe firmly, press the UT5000's MEAS key.

If you have selected a pulse frequency, the UT5000 displays the maximum and

minimum values obtained so far, and the average measurement.

4. Press the STOP key to stop measuring.

If any of the measurements exceed the defined alarm settings for the RFID tag location,

the corresponding alarm setting is displayed with red text.

If you want to store the measured values, press the SAVE key. To download all saved

measurements to a PC, see page 15.
