NOTES:
1. When powered by the battery pack, the register provides local readout only with no remote output signal.
2. For wiring of explosionproof type (output available models), do not fail to use the ancillary pressure-
resistant packing.
Also, in case of TIIS explosionproof type used under the ambient temperature of 45
℃
or higher, use a
cable resistant to the temperature of 75
℃
or higher.
3. If pulse width in excess of 1ms is desired with minimum factored pulse unit, the max. flowrate can
possibly be restricted; consult the factory.
4. With meter size marked
※
, if minimum factored pulse unit is selected, pulse width other than 1ms
is unacceptable.
