allows to reset the maximum (MAX), minimum (MIN) and average (AVG)
value of the captured measurements;
ESC:

The "DATA" key is used for the following functions:
DATA:

the measurements captured by the probe connected to the instrument is displayed, updating it
with the acquisition of new samples;
-
by pressing this key again the minimum (MIN) value is displayed;
-
by pressing this key a third time the average (AVG) value is displayed.
The acquisition frequency is once a second.
The MAX, MIN and AVG values remain in the memory until the instrument is on, even after
exiting the DATA calculation function. When the instrument is off, the previously memorized
data are cleared. Upon turning on, the instrument automatically starts memorizing the MAX,
MIN and AVG values.

perform the ENTER function and the MENU can be browsed and the displayed parameter
confirmed. During electrode calibration, it allows to decrease the nominal buffer value.
The
HOLD
