Turns on the gauge. When pushed, the GeoGauge goes
through an electronics check, displays the present battery
voltage and finally displays the value of the previous or last
measurement made. The gauge is then ready to perform
a new measurement.
Turns off the gauge.
To execute any of the four buttons with a blue background
( “ERASE”, “PRINT”, “TEST”, “UNIT”), you must first press the
“SHIFT” button. After pressing “SHIFT”, do not press the blue
keys until “SHIFT” is displayed in the STIFFNESS window.
Note: the “STOP” button does not require using “SHIFT”.
Erases all saved data. Starts measurement ID at "1"
Saves the current measurement. This button must be pushed to
save each measurement. If it is not pushed, the data for the last
measurement will be discarded. Note: When the GeoGauge
memory is empty, the first 20 measurements saved will contain
the uniquely assigned measurement ID, measurement time
and date, frequencies and the real and imaginary parts of the
force and displacement (Research Format). There after, only the
measurement ID, the displayed stiffness in SI units, and the time
and date will be saved for the next 480 measurements. At this
point the GeoGauge's memory is full and "db full" is displayed.
Begins the downloading of data, via the IR COM port.
Shows the target stiffness value, only in SI units, in the
ID/TARGET window and the ratio of the measured stiffness to
the target stiffness in the STIFFNESS window. The target value
can be incrementally changed in graduations of 0.5 MN/m
by scrolling up or down using the "INCR" or "DECR" buttons
respectively. Press "MODE" again to return to the
previous display.
