DESCRIPTION
OF
THE
FUNCTIONS
The keyboard of the Manometer – Thermometer Model
HD2304.0
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:
to turn the instrument on press
ON
, to turn it off press
OFF
.
The turning on enables all display segments for a few seconds, starts an
Auto-test
including the
detection of the probe connected to the input, and sets the instrument ready for normal
measurement. The following is displayed:
AUTO/OFF:
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, while the
"ERR"
message is shown in the
central part of the display. When the probe is inserted into a functioning instrument, the
"NEW_PROB_DET"
(New probe detected) message appears, while the
"ERR"
message is
shown in the central part of the display, and a sequence of "beeps" is simultaneously issued. As the
data are captured upon turning the instrument on, it is necessary to turn it off and on again.
Caution!
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.
