EASURING DEPTH OF COVER

6.4 Accuracy

The reading of cover will only be accurate if all the following conditions are

satisfied:

•

The instrument has been zeroed.

•

The search head is over the centre-line of the bar.

•

The search head is parallel to the bar.

•

The search head is not over, or near, any other bars which might affect the

reading

•

The manually entered bar size has been confirmed as being accurate by

comparing with the autosize estimate.

If the reinforcement bar is too deep to measure successfully (over-range), the

depth of cover will be displayed as infinite (Figure 13).

If reinforcement bars are too close together to measure with the standard search

head, try using the narrow pitch search head. See "Accessories" on page 65 for

ordering details.
