DESCRIPTION
OF
THE
FUNCTIONS
The keyboard of the Anemometer Model
HD2303.0
is composed of
double-function
keys. The
function on the key is the "main function", while the one above the key is the "secondary function".
When the instrument is in standard measurement mode, the main function is active.
Once the Settings Menu has been opened, by pressing simultaneously the
DATA+UNIT
keys, the
secondary function is enabled.
The pressing of a key is accompanied by a short confirmation "beep": a longer "beep" sounds if the
wrong key is pressed. Each key specific function is described in detail below.
This key has two functions:
•
ON/OFF:
press this key to turn the instrument on and off.
The turning on enables all display segments for a few seconds and starts an
Auto-test
including the
detection of the probe connected to the input. For a very short time the filter used for measurements
(FAST or SLOW) is displayed; then the instrument carries on with the standard measurement.

the
AutoPowerOff
function can be disabled by simultaneously pressing this key
and the "HOLD" key when turning the instrument on.
During turning on, should no probes be connected, the
"NO_PRBE_SER_NUM"
message is
displayed in the line for symbols for a few seconds, in the main line a series of dashes appears while
the
"ERR"
message is shown in the secondary line.
Caution!
As the data are captured upon turning the instrument on, it is necessary to turn it off and
on again. Replace the probes when the instrument is off.
The instrument has an
AutoPowerOff
function that automatically turns the instrument off after about
8 minutes if no key is pressed during the intervening time.
Press simultaneously the
ON/OFF
key and the
HOLD
key
to disable this function.
In this case, remind to turn the instrument off with the
ON/OFF
key: the automatic turning off
disabling is shown by the battery symbol blinking.
