Control Display
AZ1, AZ2 Zero adjustment (AutoZero) of channel 1 or channel 2 respectively.
To initiate the autozero cycle first indicate the respective channel with the
left/ right arrow key and then press the
ENTER key. It is recommended to
check that the readout will be set to zero ( 0 ± 1 Digit). Repeat the autozero
cycle if necessary.
For correct zeroing please read the respective instructions for the
transducers, meters or controllers in use, e.g. thermal stabilization, proper
evacuating of absolute pressure transducers etc.
The PR4000F stores the detected offset of the transducer, meter or
controller in use and corrects automatically the reading by this value. In
case of MFC’s or pressure controller the setpoint which is sent out will also
be corrected automatically.
