Using the TruFirm
The TruFirm Model measures the depth the plunger de-
presses a surface when it is released from a set height. The
value of this depth is displayed on an LCD readout.
The unit will also display the average of a series of meas-
urements and the number of measurements included in the
average on its LCD.
Activating/Deactivating the Display:
The unit is activated by briefly pressing the Button. The
LCD will display the percent battery life for 5 seconds and
then show zeros when it is ready to take a measurement.
The TruFirm will power off after 5 minutes of inactivity.
Taking a reading:
1. Place the unit on the surface being measured. If the sur-
face is sloped, orient the Base so that it is pointing
downhill.
2. Step lightly on the Foot Support. This will ensure the unit
does not tip over after the reading is taken.
3. If the Display is blank, press the Button briefly and wait
for the unit to turn on.
4. Lift up the Plunger all the way. The display will now
show the number of measurements that have been in-
cluded in the average (or zero for the first reading).
5. Release the Plunger so that it drops smoothly.
6. On the first measurement, the value of the current
measurement is displayed. For subsequent measure-
ments, the LCD will display the current reading for 2
seconds and the average after 2 seconds.
To reset the average, press the Button briefly while the av-
erage value is being displayed. If the average is not reset,
the next reading will be included in the average as well.
The average will also be reset if the meter is powered off.
