Depth reading (optional)
The ColcheK
2™ display has an indication of the depth the probe is at within the column
relative to ground level.
This system uses an ultrasonic transducer and must have a reasonable line of sight between
the transmitter mounted on the probe and the receiver fitted inside the column door. To use
the depth measurement, follow the below instructions.
1.
Fit the ultrasonic transmitter to the probe close to the lower end making sure the
transmitter faces upwards and using the splitter cable provided, connect the probe and
transmitter to the “probe” connector on the ColcheK 2™. Connect the ultrasonic
receiver to the connector on the ColcheK
2™ handle and fit the receiver inside the
column with the receiver facing downwards. See Fig 2. below
Fig. 2
2.
Position the ColcheK
2™ probe at the zero position (see Fig 1) and zero the ColcheK
2™ as normal.
3.
Locate the defect as found before and keeping the probe steady use the
‘B’ button to
select the depth meter screen. Read the depth directly off the screen. Press the
‘B’
button again and read the relevant bar graph to confirm the extent of wall loss.
