2. Major Components
Handheld Meter
Bigfoot
Reference Electrode
Reinforcing Bar Connection
The following section outlines the major components of the
system with a detailed explanation to there use.
The handheld meter is the major component within the
system and carries out the Linear Polarisation test after
pressing a series of buttons.
The meter provides the following functions:
• Date & time
• Data logging up to 512 Readings
• PC Download Capability
• PT100 temperature Measurement
• LPR ID Reader (permanent probes only)
To carry out the corrosion rate measurement the big foot is
used to record the Corrosion potential (Ecorr) utilising the
reference electrode and pass a small current through the
integral Auxiliary electrode (AE).
The reference electrode is attached to the Big foot for
recording the corrosion potential from the reinforcing steel.
In carrying out the corrosion rate measurement the
handheld meter must be provided with a connection to the
reinforcing steel. This is carried out by either a single
connection (WE) if less than 10metres from the meter or by
two connections (WE & SENSE) for distances up to 30
metres.
NOTE: No testing should be carried out in excess of 30
metres and additional reinforcing steel connections are to be
made.
When using a single connection to the reinforcing steel the
supplied link must be installed between the WE and SENSE
terminals on the meter.
