6.2.1 Compensation for height differences
If a significant height difference exists between the CPT6000 reference pressure sensor
and the test item, then the pressure difference, based on a medium column, can be
compensated automatically via the menu (see chapter 6.7.5 “SETUP additional menu
items: CPH configuration”).

6.2.2 Important instrument settings for calibration using calibration mode
Calibration date
The instrument has an integral real-time clock with date. The current date of a calibration
is stated later in the calibration certificate. Before starting a calibration, you must ensure
that the internal date of the CPH7650 is correct (see chapter 6.7.5 “SETUP additional
menu items: CPH configuration”).
Unit and resolution
After selecting one of the main menu items (e.g.: MEASURING , CALIBRATION or
SWITCH TEST ) from the SETUP menu (press SETUP button), using the menu item
“Unit”, and its associated submenu respectively (move the cursor to “Unit” and press
the right or left arrow), you can set the unit and adjust its resolution (see chapter
6.6 “Operating modes”).
For available units, incl. their conversion factor in relation to the unit bar, see chapter
