FUNC/ENTER key
It enables the display and logging of the maximum (MAX), minimum (MIN) and average (AVG)
value of the measurements captured by the probe connected to the instrument, updating them with
the acquisition of new samples. The acquisition frequency is once a second.
In the models with two inputs, the HD2128.1 and HD2128.2
, on activation of the key the two
display lines represent the MAX, MIN or AVG values for both inputs.
In the models with one
input, the HD2108.1 and HD2108.2
, the display shows the current temperature in the main line
and the maximum, minimum or average temperature in the secondary line.
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.
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 MENU
key down (please see the ON-OFF key description).
UNIT/UserCAL key
During measurement allows selection of the unit of measurement for the input temperature. By
repeatedly pressing the function key, the different units of measurement are displayed in sequence:
1.
°C
Celsius
degrees
2.
°F
Fahrenheit
degrees
3.
°K
Kelvin
degrees
4.
mV
voltage in mV generated by the probe (hot junction)
5.
mV*C voltage in mV equivalent to the read temperature indicated at 0°C.
Represents the voltage signal reported by the table illustrating the thermocouple.
This setting changes the information displayed and the immediate print of data (SERIAL key).
The
data recorded using the LOG function (
HD2108.2 and HD2128.2
) and sent to the printer or
PC through the serial port using the SERIAL function, keep the chosen unit of measurement
and display it.
