Delfin ElastiMeter User Manual page 7

Used contact force and measurement speed levels are shown on
the display. Recommended force and speed levels are indicated
with a green bar on the display. High speed warning may also
occur if the indenter is not placed perpendicularly on the skin.
Proceed by pressing the operate button and re-measure, or wait
until the message READY is displayed.
3. Five short, successful measurements on the same site have to be done
to get the ISE reading. The shown ISE reading is the mean of 5
consecutive measurements. Readings under the recent value are means
of previous measurements.
If the probe is left on the skin for too long, the message OFF SKIN is displayed.
Remove the probe from the skin and press the operating button to re-measure.
Avoid touching the indenter and the base plate with your hand or fingers. They
should touch the skin only during the measurement.
The ElastiMeter is automatically switched off, if the next measurement is not
started within 30 seconds.
The ISE reading is a quantity which indicates the instant skin elasticity in units
N/m. The measured values increase with increasing elasticity.
