We recommend a reset every 5 minutes or so. On power on, the Profoscope re- minds the user to perform a reset. Hold the Profoscope in free space (no metal within a 40cm / 16” sphere) and press the reset key. The dis- play rotates for approximately 2.5s while the reset is car-... -

Page 6: The Measuring Range
2.2 The Measuring Range The pulse induction principle used by Profoscope has a defined range of operation. The measuring range is dependent on the bar size. The expected accuracy of the cover measurement is indicated in the graphic below. (Complies with BS1881 part 204, for a single rebar with sufficient spacing). -

The following two charts give an estimation of the error in percentage of the cover reading for different rebar sizes if a default size of 16mm (#5) is set. For the short range: Cover depth For the long range: Cover depth © 2008 by Proceq SA... -

2.3.5 Orientation The strongest signal results when the center line of the probe is parallel to a bar. The center line in the Profoscope is the long axis of the instrument. This property is used to help determine the orientation of the rebars. -

Page 11: Preparation
3.2.1 Finding a Rebar Step 1 – Place the Profoscope on the test surface and move it slowly in a chosen direction. The Profoscope re- acts differently depending on its orientation relative to the rebars. - Page 12 It is very simple to differentiate between the two. Approaching a Rebar Rifle scope moves in opposite direction to the Profo- scope. The signal strength is increasing as the rifle scope moves towards the center line. Approaching a Mid-point © 2008 by Proceq SA...

Page 14: Check The Orientation
Note: The signal strength arrow can also be used as an aid here. The signal strength will in- crease as you rotate towards the correct orienta- tion and decrease as rotate away. © 2008 by Proceq SA... -
Page 15: Verification
Mark at either end of the instrument with chalk or similar. 3.2.3 Verification Step 3 – Verify by moving the Profoscope in the direction of the rebar and observe that the cover depth reading dis- plays a constant value. -

Step 1 - If you already know the actual rebar dia- meter, select the icon in the menu to set this as the reference. Note: If you DO NOT know the rebar diameter, then proceed to chapter 3.4. © 2008 by Proceq SA... -
Page 17: Read The Cover Depth
3.3.2 Read the Cover Depth Step 2 - Place the centre line of the Profoscope directly over the rebar and read off the cover depth. e.g. Cover depth = 15 mm Note: Ensure that the measurement centre is not placed over a horizontal/vertical intersection in the rebar grid. -
Page 18: Measure Rebar Diameter
Move the Profoscope over the test surface. Whenever the cover depth is less than the programmed minimum the LED indicator will light and if it is enabled, an acoustic alarm will be given. -

150 mm (6”) spacing to a neigh- boring rebar. Step 4 - Place the centre line of the Profoscope over the rebar and click the function key on the left side. The measured rebar diameter replaces the signal strength arrow. -
