4. OPERTION
This measuring instrument is capable of saving 2 data records (record 0,
record 1). Through a short press on the button which is on the le side from
the display, it is possible to retrieve the next record.
In case of a failure of the power supply, data record 1 saves the last saved
value and continues from this value aer the restoring of the power supply.
In case of a failure of the power supply, data record 0 shows the last values
through blinking. These values will be reset if they reach the 0.01 Ah.
To delete each data record, the button must be pressed more than 3 seconds.
Temperature changes and / or ageing of the components can lead to
measurement errors. In such cases, you can make a zero calibration. For this
purpose, you must disconnect the device from the power supply. To perform
the zero calibration, the button needs to be pressed and simultaneously the
power supply have to be restored. At a successful calibration, the display
shows “AAA“.
