Note:
 All calibration points are deleted automatically from the probe memory after adjustment.
 The
text line Delete can be used to delete all calibration points before probe adjustment.
 Since the PF4 does not have a real-time clock, the date of the adjustment is not written in the probe. If it
is important to record the adjustment date, use the HW4 software to adjust the probe.
7.4 Validation of Analog Output Signals
Using the HW4 software, it is possible to set fixed values with which the analog output signals can be validated.
8 Firmware Update
The firmware can be updated with the HW4 software. Firmware updates are available for downloading on the
ROTRONIC website. To update the firmware, the PF4 must be connected to the HW4 with service cable
AC3006. The PF4 must remain connected to the computer throughout the update process and there must be a
stable power supply for the complete duration of the process.
Flashing of the display backlight indicates a firmware update is in progress.
