Operating instructions - digital oval gear meter and pulse meter
US
During calibration, the registers on the LCD display - that normally show partial and total volumes of liquid
output - will take on new meanings.
During calibration, the meter cannot carry out normal output operation.
During calibration, the count of the absolute total volume of liquid having been output (non-resettable
total) will not increase.
NOTE
The oval gear meter is equipped with a non-volatile memory so that saved
calibration data and the total output amount will be stored for prolonged periods
of time - even without power supply. That means you don‘t have to re-calibrate
after you have exchanged the batteries.
8.3.1 Displaying the valid calibration factor - resetting the factory calibration factor (if necessary)
Go to default standby mode. Press the TOTAL button. The display shows the valid calibration factor.
Two situations are possible:
a) User never changed the calibration factor and/or user restored the factory calibration factor after
changing it: the display will show the following:
The word FACT (short for FACTORY) indicates that the valid calibration factor is the factor pre-set at the
factory.
b) If calibrations have been made by the user, the calibration value currently used is indicated
(in our example 0,998).
The word USER indicates that the calibration factor currently used was entered by the user.
The ow chart below shows the schematics of the display modes the LCD display may go through.
In this mode, the user may press RESET and thus change from the USER to the FACTORY FACTOR.
In order to conrm your choice, shortly press TOTAL while the display shows either USER or FACT.
After re-start, the meter will use the new calibration factor you just conrmed.
