(compression).

– Elastometer: Operation and Display Elements
Operation
The Elastometer is switched on or off by briefly holding the on/off switch. The display shows
the current measure value, the battery voltage and the module address. After switching on, the
firmware version, module address and the individual serial number of the respective measuring
instrument are temporarily displayed.
By pressing the OK button once, the Elastometer changes to the offset mode ("zeriong"). By
pressing the OK button again, the five second calibration cycle of the offset value is initiated.
In most applications, it is recommended to have the offset value determined by a command
from the com unit for all modules simultaneously. Ideally, this is done immediately before the
actual measurement, the app does so automatically.
If the OK button is held down for 3 seconds, the Elastometer switches to the address menu.
Here the module address can be set by pressing the OK button. To save the set address,
press and hold the OK button for three seconds.
Elastometers are equipped with a mechanical lock of the actual measuring apparatus. If this
button sticks out on the back (side away from the display), the mechanics is locked. If the
button protrudes from the display, the mechanics are free and ready to measure.
