6.12 MIN/MAX memory
The CPH65I0 has a MIN/MAX function for capturing the minimum and maximum values
of any displayed parameter.
The MIN/MAX function can be set by stepping through the menu options until "MIN/
MAX" is shown on the display above the F1 key. At this point, pressing the F1 key
will scroll the display through the MIN/MAX values that are stored in the "MIN/MAX"
registers. These readings are live so new MIN/MAX values will be recorded while in this
mode.
To clear the "MIN/MAX" registers, simply press the "CLEAR" key. These registers are
also cleared on power-up or when the configuration is changed.
7. Maintenance, cleaning, and recalibration
7.1 Maintenance
The model CPH65I0 hand-held pressure calibrator is maintenance-free.
Repairs must only be carried out by the manufacturer.
This does not apply to the battery replacement.
7.2 Replacing the batteries
To avoid false measurements, replace the batteries as soon as the battery indicator
comes on. If the batteries run too low the CPH65I0 will automatically shut down to avoid
the batteries leaking.
WARNING!
■ Only use permitted size AA alkaline batteries as described in the
following table.
■ Only replace the batteries outside the hazardous area.
