Page 4: Getting Started
Oscilloscope Batteries USB – PC / Power Supply The Pundit Lab can be powered by batteries, by the mains or by the USB connection to a PC. Front Panel The soft keys are context sensitive. The display icon shows the active function. - Page 5 Zeroing the Pundit Lab The Pundit Lab should be zeroed using the calibration rod on a regular basis and in particular if the transducer frequency is changed or if the cables are changed. The expected calibration value (µs) is marked on the calibration rod.

Page 6: System Settings
Automatic Gain and Voltage Setting The excitation voltage and the receiver gain can both be set to automatic. In this mode the Pundit Lab finds the optimum combination of the two parameters for a stable measurement. © 2017 by Proceq SA... - Page 7 (Refer to ASTM D 2845 - Standard Test Method for Laboratory Determination of Pulse Velocities and Ultrasonic Elastic Constants of Rock.) It also allows non-standard transducers up to 500 kHz to be used with Pundit Lab: Pulse width “p” in microseconds (µs) to be entered here is calculated from the formula...

Page 8: Viewing The Waveform
4. Viewing the Waveform While carrying out the measurements described in the following chapter it is possible to view the received waveform. Pundit Lab offers three possibilities to look at the waveform. Oscilloscope Connect an oscilloscope to the connector on the rear panel. A typical waveform will look like... -
Page 9: Measuring With Pundit Lab
The location of rebars should be determined using a rebar locator such as Proceq's Profoscope and ultrasonic tests should be positioned so as to avoid them. BS 1881 Part 203 gives information on the effect of rebars on the expected results. -

Adjust the gain settings. (See Chapter 3) or: Start a new measurement * Best results are obtained when the received signal level is around 75%. Use the automatic gain and voltage settings (See Chapter 3) for optimized performance. © 2017 by Proceq SA... -
Page 12: Basic Measurement - Waveform Display
Note 1: Rx gain may need reducing for vertical zoom to have a noticeable effect. Note 2: Once adjusted, trigger point does not reset automatically unless a new measurement is started in the menu “Start the measurement” Note 3: The waveform is not saved, only the transmission time. © 2017 by Proceq SA... -

Page 14: Basic Measurement - Compressive Strength (Pundit Lab+ Only)
5.6. Basic Measurement – Compressive Strength (Pundit Lab only) Prior to carrying out this measurement, a conversion curve must be created in PunditLink and uploaded to the instrument. Up to five curves may be stored on the instrument. Select the appropriate curve and set the desired compressive strength unit. -

The menu item “File – Application settings” allows the user to select the language and the date and time format to be used. Connecting to a Pundit Connect the Pundit to a USB port, then select one of the following options: © 2017 by Proceq SA... -
Page 23: Viewing The Data
• The “Name” column allows the user to assign a name for the measurement object. • The “Date and time”. For Pundit Lab this is the time when the data is downloaded on to the PC, or in “Live view” mode, the date and time when the measurement was made. For Pundit Lab it is the date and time when the measurement was made. -
Page 24: Adjusting The Settings
Right click in the “Date & Time” column. The time will be adjusted for the selected series only. Please note, the Pundit Lab does not have an internal clock, so the date and time displayed for downloaded data, is the time at which it was downloaded. -
Page 25: Exporting Data
In both cases, the preview window shows the effects of the current output selection. Finish by clicking on export to select the file location, name the file and in the case of a graphi- cal output to set the output graphic format: .png, .bmp or .jpg © 2017 by Proceq SA... -

Page 27: Live View
9.7. Live View Pundit Lab allows you to remotely control the Pundit Lab and to view the waveform directly on the PC screen. Click on the “Live view” icon. If you are not already connected to the Pundit, the connection sequence will be initiated. (See 9.1). The “Live view” window will be displayed. - Page 28 Recording time set to 0.5 ms e.g. Recording time set to 5ms Setting the trigger point manually Pundit Link gives the user the option to set the trigger point manually. See the example below. Trigger point capture automatically. © 2017 by Proceq SA...

Page 30: Conversion Curves
Live mode The live mode allows the user to test with or without recording the data. In continuous mode, the Pundit Lab begins measuring as soon as “Start” is pressed and continues until “Stop” is pressed. If a limited number of readings only is required, this may also be set. -
