8.2 Example of displayed EPM-XP values during pressure check
Indicated pressure [bar] at calibrator Displayed pressure [bar] at EPM-XP
Deviation +/-2.5
0 0 0
100 99 1
200 198 2
Note: The max. acceptable difference between adjusted pressure at pressure calibrator by ambient (20-25°C)
temperature and displayed static pressure at EPM-XP is +/- 2.5 bar. By increasing pressure difference we
emphasize to send EPM-XP unit to IMES workshop for new adjustment and calibration.
The accuracy of the EPM-XP unit acc. technical data is +/- 0.5% full scale (0…300 bar) between adjusted
temperature range of 50°C- 200 °C.

8.3 Disconnect EPM-XP from pressure calibrator
The thompson adaptor of EPM-XP must be dismounted from adaptor of pressure calibrator. After disconnection
the thompson adaptor incl. gas channel of HTT cylinder pressure sensor must be cleaned from oil by using pres-
surized air.
