DESCRIPTION
OF
THE
FUNCTIONS
The keyboard of the Thermocouple Thermometer Model
HD2328.0
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.
In the menu, the secondary function is enabled; press the
DATA+(A-B)
keys together to open the
menu.
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.
The
HD2328.0
measures the temperature at the two inputs: the temperature measurement at the "A"
input is displayed in the main line, while the secondary line shows the value at the "B" input.
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, and then the type of calibration
enabled (CAL FACT = factory calibration; CAL USER = user calibration).
•
AUTO/OFF:
the
AutoPowerOff
function can be disabled by simultaneously pressing this key
and the "HOLD" key when turning the instrument on.
If no probe is connected to one of the input connectors, the "BURN" message appears in the
corresponding line, that is, in the first line for input "A" and in the second line for input "B".
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, remember to turn the instrument off using the
ON/OFF
key: disabling of the automatic
turning off is shown by the blinking battery symbol.
