Bar Sizing Accuracy |
± 0,5mm to ± 1.5 mm |
|
|
|
Dependent on bar size and cover depth and the closeness of other bars. Error codes indicate to the |
|
user if there is too much or too little cover for a bar size to be estimated. Otherwise the bar size is |
|
indicated and the current bar size used by the 8020 is updated automatically, resulting in greater |
|
depth indication accuracy. |

|
Bar Sizing |
The minimum depths of between 8-22 mm of cover, which are dependent on the bar size, can be |
|
overcome by the introduction of any spacer when the bar is too close to the surface. |
|
Typically a 6 mm bar can be sized down to 60 mm of cover |
|
|
and a 40 mm bar can be sized down to 80 mm of cover. |
|
Cover Depth Measurement Range |
|
|
|
|
From 5 to 185 mm dependent on bar size. Readings closer to zero can be achieved by insertion of |
|
spacer of known thickness to increase distance of probe from target. |
|
Cover Depth Accuracy |
to 1 mm |

The PC application communicates with the 8020 via a serial port and enables the downloading |
|
directly into a Microsoft Excel spreadsheet format (*.csv file). This will include the facility to |
|
download a selected range of logged data "points" such that only the required data is transferred |
|
to the spreadsheet. This program is simple to install and works with Windows 2000, ME & XP. |
