FUNC/ENTER key
During normal measurement this enables the display and logging of the maximum (MAX),
minimum (MIN) and average (AVG) value of the measurements captured by the Pitot tube
connected to the instrument, updating them with the acquisition of new samples. The acquisition
frequency is once a second.
The calculation is performed on the pressure, wind speed or flow rate appearing on the display upon
pressure of the FUNC key: by changing the unit of measurement, the Max, Min and Avg values are
cleared.
The MAX, MIN and AVG measurements remain in the memory until the instrument is on, even
after exiting the calculation function. To reset the previous values and restart with a new
measurement session, press FUNC until the message "FUNC CLR" appears, then use the arrows to
select YES and confirm using ENTER.
In the menu, the ENTER key confirms the current parameter and then goes to the next one. Pressed
together with the UNIT/DuctCalc key, enables the flow rate calculation (please see the UNIT key
description).
Attention: the data captured using the Record function cannot be transferred to the PC
.
HOLD/
key
It increases the current parameter when used in the menu; when used in measurement mode, it
freezes the measurement in progress, and upon application of pressure on the key, the message
HOLD
appears in the upper side of the display. To return to the current measurement, press the
key again.
Upon turning on the instrument, the
AutoPowerOff
function can be disabled by holding the HOLD
key down (please see the ON-OFF key description).
UNIT key
In measurement mode, it allows selection of the unit of measurement of the pressure, wind speed
and calculated flow rate (shown in the central line of the display). By repeatedly pressing the key,
the different units of measurement are displayed in sequence: Pa, mbar, mmH
2
O, PSI for the
differential pressure, m/s, km/h, ft/m, mph, knot for the wind speed and l/s, m
3
/h, cfm for the flow
rate.
This setting changes the information displayed and, for the HD2114P.2 and HD2134P.2 models the
immediate print of data (SERIAL key).
The data recorded using the LOG function (
HD2114P.2
and
HD2134P.2
) keep the chosen unit
of measurement displayed during logging.
The unit of measurement associated with the data sent to the printer or PC through the serial
port using the SERIAL function (
HD2114P.2
and
HD2134P.2
), must be selected before
starting the print function.
