6.14 MIN/MAX memory
The calibrator 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
Repairs must only be carried out by the manufacturer.
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 CPH6600 will automatically shut down to avoid
the batteries leaking.
Only AA size alkaline batteries or rechargeable batteries, from the
optional CPH6600 accessories, should be used.
CAUTION!
To avoid personal injury or damage to the calibrator, only use
accessories supplied by WIKA and ensure that no water finds its way into
the case.
