7. Effect of Cover Meter Probe Setting (Low or High)
All covermeters have different measurement probes to measure the full range of concretecovers, either by using a universal probe with different probe settings (low or high range) orby using two different probes (deep or shallow). In the over lapping range where both probesettings could measure concrete covers, the measured covers by different probe settings donot match. Manufactures recommend that high range setting should only be used if the
concrete cover could not be detected when the probe is set to low range.
