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 RESOLUTION    0.1 mm
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 6mm bar can be sized down to 60mm of cover
and a 40mm bar can be sized down to 80mm of cover.

COVER DEPTH MEASUREMENT RANGE                
From 5 to 185mm 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 1mm

BAR RESOLUTION
Dependent on bar size and cover. Some examples are shown here.

DATA LOGGING CAPABILITY
The logging capacity is 10000 bits of information comprising:

• Cover measurement
• Bar size
• Date
• Time
• Log Number

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 has been tested on Windows 2000, ME and XP.
