1. the larger this effect will be Likewise when a system is put under pressure the tubes cavity etc will expand somewhat over time and hence the volume will increase and the pressure will drop as a function of the increased volume When pressure is introduced into the PM105 system by the pump a large amount of energy is stored in the unit When doing so the temperature of the oil will increase slightly as part of the introduced energy For this reason and the reasons listed above the indicated pressure will drop slightly over time as the system stabilises its increased temperature and the expansion of the tubes etc Depending on the applied this will normally take a few minutes If a pressure is generated e g 200 Bar and then dropped quickly down to e g 100 Bar the reverse function a slight increase in the pressure will occur for the same reasons If the ambient temperature changes over time and the unit is set to a fixed pressure the reading will change as a function of the change in temperature The above is a normal physical behaviour and should be taken into account in the operational procedures PM105 is temperature compensated over the entire temperature range and as such can be used with the listed accuracy In order to obtain full accuracy it is important to let the PM105 obtain the ambient temperature in the actual measuring environment This process may take approximently 3 hours Particular attention should2.
