3) Calibration by Comparison to a Standard Thermomter / oP2
Use the up and down keys [

] to select oP2 . Push [ENTER/MENU] to confirm.
On the bottom of the display appears 1 P . For changing between a 1-Point 1 P , 2-Point 2 P or 3-Point 3 P -
calibration use the up and down keys [

].
oP2
1 P 2 P 3P
Example of a 1-Point calibration:
Push [ENTER/MENU] to confirm. On the display appears CALC . After the displayed measuring value is stabile push
[ENTER/MENU]. On the first display line you can see the “frozen” measurement value. On the second line as a
default you can see -100.000 . Now you have to Enter (instead of -100.000) the correct measurement value from
your reference:
By using the up key [

] you are able to move the decimal point to setup the number of decimal places. Push
[ENTER/MENU] to confirm.
Now the algebraic sign is blinking
„-„
. Use the up key [  ] to toggle for positive or negative number. Change the
number using the up and down keys [

].
Note:
Up key

is changing the blinking segment
Down key

is jumping to the next segment
Push [ENTER/MENU] to confirm, revert back to the measuring mode.
Important: A break of the physical calibration cannot be done by the [ESC]-button.
Display-indication with active calibration code (OP2):
The CAL -segment and the small 2 indicates to the user that oP2 is activated.
4) Calibration according to Coefficients of EN60751 (R0,ABC)
By using Option 3 you are able to activate coefficients according to EN60751 (R0,A,B,C). The coefficients have to be
calculated using special software on a PC (e. g. P7_CALC). Before you are able to activate this option you have to
transmit the coefficients from the PC to the instrument.
Use the up and down keys [

] to select oP3 . Push [ENTER/MENU] to confirm.
Now the calibration option 3 is activated. Push [ESC] to revert back to the measuring mode.
Note: After confirming oP3 by pushing [ENTER/MENU] the function oP3 (calibration by code) is activated, even
though you leave the menu by pressing [ESC].
Display-indication with active calibration code (OP3):
The CAL -segment and the small 3 indicates to the user that oP3 is activated.
5) oP4 Reserved for future use, not currently implemented
