Taking A Reading - Elcometer 224 Operating Instructions Manual

Selecting Auto will enable the gauge to automatically select the
appropriate brightness for the surrounding light conditions using the
internal light sensor.
Screen brightness can also be changed via Menu/Setup/Screen
Settings/Screen Brightness.
Note: Manually increasing the screen brightness will reduce battery life.
Adjusting the beep volume
Each time a measurement is taken, the gauge will beep. The beep
volume can be adjusted and can even be switched off via
Menu/Setup/Beep Volume.

3 TAKING A READING

1. Hold the gauge (integral) or the probe by its sleeve (separate gauge)
2. To take a reading, bring the probe down onto the surface whilst holding it
perpendicular
3. For subsequent readings, lift the probe off and then replace it onto the
surface
4. To accurately assess the surface profile 5-10 readings should be taken
over a surface area of 150mm (6 sq. in.). The average of these readings
will indicate the surface profile peak-to-valley height of that area.
Users can pre-define the number of readings using the counted average function. When
in batching (Model T), press Batch/New Batch/Batch Type, select "Counted Average"
and set the number of readings as required. The average of this pre-defined number will
be saved into the batch, but the individual readings within the counted average are not
saved. When not in batching (Model B & T), press Display/Statistics/Counted Average
and set the number of readings as required. When using counted average, the gauge
switches between displaying statistics based on individual readings to statistics based on
the counted average, as each set of reading are taken.
DO
• Hold the probe by the probe sleeve
• Firmly place the probe onto the
surface
• Allow the metal base to make
contact with the surface - to
improve accuracy
