Issued on October 2012, revision 1
Specification subjected to change with out prior notice
The P100 Calibration Adjustment is done electronically, by keyboard with-out the need to open the
unit. It is performed over 5 positive calibration points in steps of 20% of the Full Scale and vacuum
points ( for ranges up to 60 bar g ).
The calibration procedure is carried out at 20 C +/- 3 in normal laboratory conditions
Recalibration/adjustment of the P100 is only recommended if the “as found”data after verification
are outside the specified tolerance. The calibration procedure needs to be completed as a whole to
ensure the correct reading of the indicator.
Equipment
It is up to the user to ensure that a correct standard equipment is used to perform the calibration
procedure. You will need a reference standard capable of generating vacuum and pressure up to the
FS of P100 with a TUR of at least 3 to 1.
Connecting the P100 to the Standard
The P100 uses a ½ “BSP male to connect to the process so you might need an adapter to connect to
your reference. Please make sure that hoses, fitting and adapter have the correct working pressure
rate before starting to generate any pressure. Also ensure that the system is leak free. Eurotron

Calibration Procedure
PO : ensure that the system is in vent ( atmospheric pressure)- Press ZERO and then confirm with
SET
P1= 20% of the FS
Set the out pressure to 20% of the FS of the P100 ( for example on a 10 bar g unit, set the pressure
to 2 bar). Once the pressure is table, adjust the reading on the P100 by using the up and down
arrow keys. Confirm by pressing SET
P1= 40% of the FS
Set the out pressure to 20% of the FS of the P100 ( for example on a 10 bar g unit, set the pressure
to 4 bar). Once the pressure is table, adjust the reading on the P100 by using the up and down
arrow keys. Confirm by pressing SET
P1= 60% of the FS
Set the out pressure to 20% of the FS of the P100 ( for example on a 10 bar g unit, set the pressure
to 6 bar). Once the pressure is table, adjust the reading on the P100 by using the up and down
arrow keys. Confirm by pressing SET
P1= 80% of the FS
Set the out pressure to 20% of the FS of the P100 ( for example on a 10 bar g unit, set the pressure
to 8 bar). Once the pressure is table, adjust the reading on the P100 by using the up and down
arrow keys. Confirm by pressing SET
P1= 100% of the FS
Set the out pressure to 20% of the FS of the P100 ( for example on a 10 bar g unit, set the pressure
to 10 bar). Once the pressure is table, adjust the reading on the P100 by using the up and down
arrow keys. Confirm by pressing SET
DP= Decimal point
Select the correct decimal point by moving with the up and down arrow keys. Press SET to confirm.
Switch off the P100
For Vacuum Adjustment please use password 2124 and repeat the above procedure.
