 Turn the HART
®
Communicator on.
After power on, the Start menu appears.
Tip
Push the HOME button to return to the Start menu from any level.
First operation of the system:
 Set the basic parameters for the Uni-Probe (see page 3–346).
Calibration of a system that has already been taken into opera-
tion:
If you are sure that the detector and basic configuration of the
Uni-Probe is correct, you can start with the calibration of the mea-
suring system immediately as described in section 4.2.
Otherwise proceed as follows:
 If a password has been defined for the Uni-Probe, revoke the
password protection (see page 3–369).
 Reset the Uni-Probe to the factory settings (see page 3–342)
 Set the parameters for the detector HV (see page 3–344).
 Set the basic parameters for the Uni-Probe (see page 3–346).
