Taking A Reading - Elcometer 500 User Manual

5 TAKING A READING

5.1 BEFORE YOU START
1 Switch the gauge on - see Section 4.3 on page en-5.
2 Connect a probe - see Section 4.4 on page en-6.
3 Oil the sensor plate or replace the probe tip if required - see Sections
4.5 and 4.6 on pages en-6 and en-7.
The gauge will inform the user when oil is required and when the probe tip is

worn or damaged and should be replaced.
4 Set up the gauge parameters - see Section 7 on page en-10.
5 Calibrate the gauge - see Sections 9 and 10 on pages en-15 and en-16.
5.2 TAKING A READING IN STANDARD MODE
1 Apply a small amount of couplant to the coated surface.
2 Press the probe into the couplant, ensuring that the probe is flat
against the surface.
3 The display will show a value which is constantly updating (Figure 1).
 The stability of the reading is indicated on the
signal strength indicator to the right of the
display. If the signal strength indicator is green,
it is a valid and stable reading. If not green,
ensure there is an adequate film of couplant
beneath the probe and that the probe is seated
flat against the surface. Alternatively, position
the probe nearby on a different area of the
test surface until a strong signal is received.
'<0.15mm' or '>2.50mm' ('<6mils' or '>98mils')

indicates a reading outside the probe range
when using a C1 probe or '<0.75mm' or
'>10.00mm' ('<30mils' or '>390mils') when
using a C2 probe.
4 Press 'Save' to store the current reading
in the gauge or batch (Model T) memory.
5 Remove the probe from the surface .
The reading value turns grey when the probe

is removed from the surface (Figure 2).
5.3 TAKING A READING IN SCAN MODE - MODEL T
Scan mode allows measurements to be taken quickly over a large surface
area by sliding the probe across the coated surface. In Scan Mode, the
gauge takes readings at an increased measurement rate and at the end of
each scan, the average, lowest and highest reading for the scan are
displayed and all three values are saved in the gauge or batch memory.
1 Enable 'Scan Mode' via Menu/Setup/Reading/Scan Mode.
2 Apply a small amount of couplant to the coated surface.
3 Press the probe into the couplant, ensuring that it is flat against the
surface.
