Changes the unit of measurement for the temperature between Centigrade or Fahrenheit.
When used in the menu, it clears or cancels the active function.

key
In measurement mode, it displays the difference between the current value and that measured on
pressing the key for both measurements - main and secondary. The
REL message appears on the
display; press the key again to return to the current measurement.
When used in the menu, it decreases the current variable value.

PEAK/MENU key - only HD21...4.2
The first menu item is accessed by initially pressing on the MENU key (FUNC/ENTER +
PEAK/MENU in the HD21...4.2 models); press ENTER to go to the following items. To modify the
item displayed, use the arrow keys (

and

). The current value is confirmed by pressing the
ENTER key and the display moves on to the next parameter. If pressing ESC the setting is
cancelled.
To exit the menu, press the MENU or the PEAK/MENU key at any time.
The menu items are listed in this order:
1) Differential probes resetting : In the differential probes there can be a slight difference
between the two inputs, so the instrument does not indicate zero at comparable pressure
applied to the two inputs of a probe. This is the reason the reset command was designed for
the differential value: leave the inputs of each probe open so that they detect the same
pressure and enter the menu. The "PRES_REL_TO_ZERO ENTR_TO_MENU" message
appears: press REL to reset the difference or press ENTER to access other menu items.
The
reset operation is applied to the internal pressure sensor if no differential probe
(TP705) is connected to the input.
2) Pressure probe full scale: the full scale and the enabled pressure probe type is presented.
3) Probe type
: the message “>>>_PRBE_TYPE" is scrolled in the comment line. The main
line in the center of the display shows the type of temperature probe connected to the
instrument.
It is possible to connect:
Pt100 temperature probes complete with SICRAM module
4-wire Pt100 probes complete with TP47 module
2-wire Pt1000 probes complete with TP47 module
2-wire Ni1000 probes complete with TP47 module
