Every time you (shortly) press RESET, one of the other combinations of units will be displayed one after the
other (see gs.):
Long pressing of the TOTAL button will result in the new settings being stored and, after completion of the
start cycle, the meter will show delivery in the new measurement units.
Tip
The registers of the resettable and non-resettable totals will automatically switch over to the new

You do NOT have to re-calibrate after changing the units.
8. Service
This oval gear meter has been designed for minimum maintenance requirements. What remains to be
done from time to time:
Exchange the batteries when discharged.
Clean the measuring chamber. This may be necessary from time to time depending on the specic
liquid(s) being measured and/or when foreign matter gets into the chamber (inlet lter not sucient).
8.1 Exchanging batteries
The meter is supplied complete with two 1.5 V alkaline batteries (1N).
The meter has a two-step low battery indicator:
1) As soon as the batteries dip below the rst charge level the battery icon in the display will light up.
The meter will continue to operate correctly, but the user is informed that the batteries should be
exchanged as soon as possible.
2) If the batteries are not exchanged, the battery will sooner or later reach the second alarm level. Normal
operation is no longer possible. At this state, the battery icon will ash, being the only thing that is still
visible in the display.
