3. Operation

The information provided in this manual covers all applications supported

by the Pundit Touchscreen.

3.1 Getting Started

Battery Installation Pundit Touchscreen

To install the Battery into the Pundit Touch-

screen Unit, lift the stand as shown. Insert the

battery and fasten in place with the screw.

There are two status LEDs 1(see page 11) and above them a light

sensor. The upper LED is red while charging and turns to green when it is

fully charged. The other LED is application speciﬁc.

NOTE! Only use the power supply provided.

• A complete charge requires approx. 9h (Instrument not operating).

• Charging time is much longer if the instrument is in use.

• An optional quick charger (Part No. 327 01 053) can be used to charge

a spare battery or to charge the battery outside of the instrument. In

this case it takes approx. 4h for a complete charge.

Energy Saving

Energy saving may be programmed as desired under System/Power set-

tings.

Connecting the Transducers

(G)

Connect the Transducers to the Pundit Touch-

screen Unit using the BNC Adapter Cable

and the BNC Cables. Ensure that the screws

are fastened on the BNC adapter cable.

USB Host:

Connect a mouse, keyboard or USB stick.

Buttons

Lift the protective visor.

At the upper right of the screen there are three buttons 2(see page 11).

Power On/Off – Press to power on. Press and hold to power off.

Soft Key – Open a pdf document (e.g. Operating instructions) or

toggle full screen view.

Back Button – returns to previous screen.

Battery Installation Pundit Array Transducer

Remove the battery pack from the Pundit Array Transducer by loosening

the two screws and pulling out the battery pack. On the underside there

is a plate which has to be removed by unscrewing two screws to access

the battery compartment.

NOTE! Insert the six AA NiMH rechargeable batteries into the

battery pack being sure to observe the correct polarity and

replace into the Pundit Array Transducer. Before ﬁrst use, ful-

ly charge the batteries using the charger provided. While the

battery is charging the status LED is green. It will extinguish

when fully charged. A full charge takes about 2.5 hours.

By pressing and holding the fuel gauge button, the actual

charge statues can be seen. Each LED represents 20%

charge, so all 5 LEDs lit indicates a charge of more than 80%.

Any AA batteries may be used with the instrument, but the fuel gauge is

only accurate when the recommended NiMH batteries are used.

WARNING!

If standard alkaline batteries (non-rechargeable) are used, it is

very important not to connect the charger as this will result in

damage to the instrument.

3.2 Main Menu

On start up the main menu containing 6 icons is displayed.

Measurement: Application speciﬁc measurement screen.

Settings: For application speciﬁc settings.

Explorer: File manager functionality for reviewing mea-

surements saved on the instrument.

System: For system settings, e.g. language, display op-

tions, power settings.

Information: For device information and operating instruc-

tions.

Exit: Power Off.

All functions may be accessed directly via the touch screen. Return to the

previous menu by pressing the back button or the return icon (arrow) at

the top left of the touch screen.

3.3 Pundit PL-200

Scroll up and down the screen by dragging your ﬁnger up or down the

screen. The current setting is displayed on the right hand side. Tap on an

item to adjust it.

Transducer

Connected transducer

Select the frequency of the transducer to be used. The custom trans-

ducer setting allows non-standard transducers up to 500 kHz to be used.

If this option is selected, the transducer frequency must also be entered.

NOTE! When a transducer frequency is selected, the factory

settings are automatically loaded for that transducer, based

on 1.5m cables being used. Generally, the accuracy this pro-

vides is sufﬁcient for most applications, so zeroing is not re-

quired with this conﬁguration.

Zeroing Transducer

For increased accuracy or when working with different cable lengths, the

Pundit PL-200 should be zeroed.

Enter the expected calibration value as it is

marked on the Calibration Rod.

Couple the transducers to the Calibra-

tion Rod using the ultrasound Couplant

and press ﬁrmly together.

Tap on the start icon to carry out the zeroing.

On completion “Zeroing succeeded” will be displayed.

Tap to return to the settings menu.

Tap to return to the zeroing start screen.

Tap to reload the factory calibration values for the

transducer. This setting provides sufﬁcient accuracy for

most measurements, but for exact zeroing, perform the

procedure described above.

Measurement Settings

Measurement Range

Short range (default). For measurements up to approximately 800 μs.

This corresponds to a path length of approximately 3 m for normal con-

crete. This provides the maximum measurement resolution of 0.1 μs.

For larger objects select the long range. In this case the measurement

resolution is 1 μs.

The measurement screen indicates (--- μs) if a measurement is out of

range.

Pulse Repetition Frequency

Pulse Repetition Frequencies (PRF) of 5 Hz to 40 Hz (measurements per

second) may be selected. High values should be selected only when the

instrument is used on large objects with high receiver ampliﬁcation set-

tings. In such cases, it helps to increase the update rate on the display.

For general concrete or ceramic materials testing a PRF of between 10-

30 Hz is normally used.

The transducers supplied with the instrument are not damped and, there-

fore, on being excited by the transmitter they have a long ring-down time.

The ring-down time may exceed the pulse interval when the PRF is set

to high values, i. e. the previous pulse may still be ringing as the next

pulse arrives. This effect may cause errors when testing short path length

specimens having low internal damping. If this occurs reduce the PRF.

Line Scan

Line Scan provides the capability to measure along a linear grid at equal

spacing. The distance between the transducers may be varied for each

measurement to accommodate irregular shaped objects (see “3.4.2

Measurement Modes” – Line Scan).

Series Length

Set the number of measurements to be made or leave it open ended.

Distance between Measurements

Set the spacing.

Unit

Choose between pulse velocity or transmission time as the unit for the

graphical display of the results.

Units

Unit

Choose between metric and imperial units.

Amplitude Unit

Choose to display the receive signal amplitude either as a percentage or

in decibels.

Compressive Strength Unit

Choose the unit for compressive strength correlations.

E-modulus Unit

Choose the unit for E-modulus calculations.

E-modulus Density Unit

Choose the unit for entering density for E-modulus calculations.

Trigger

Amplitude Trigger

When selected, allows a user deﬁned amplitude threshold for triggering.

Drag the horizontal cursor to the desired trigger level. The zoom function

is useful to set a speciﬁc trigger threshold.

Follow Trigger

When selected, the point at which the trigger occurs is always displayed

in the centre of the screen, irrespective of the measured transmission

time. This does not apply if manual triggering or dual cursor triggering is

being used (see “3.3.1 Measurement Screen”).

NOTE! Both triggering options can be selected at the same

time. If none are selected then the triggering is carried out

automatically as normal.

Corrections

Temperature correction UPV

Pulse velocity measurements are affected by several factors. Two key

factors are the moisture content of the concrete and the temperature.

The table below shows the correction factor that should be entered

based on the recommendations made in BS 1881: Part 203.

Temperature Dry concrete Wet concrete

10 °C – 30 °C 1.0 (No correction) 1.0 (No correction)

60 °C 1.05 1.04

40 °C 1.02 1.02

0 °C 0.99 0.99

-4 °C 0.98 0.92

The correction factor is applied to pulse velocity calculations. The meas-

ured transmission time is unaffected.

Amplitude Analysis

Marker

When selected a marker is activated that can be used to record the am-

plitude of the received signal (see”3.3.5 Measuring with Pundit PL-200”).
