  We present the first gri-band period-luminosity (PL) and period-Wesenheit
(PW) relations for the fundamental mode anomalous Cepheids. These PL and PW
relations were derived from a combined sample of five anomalous Cepheids in
globular cluster M92 and the Large Magellanic Cloud, both of which have
distance accurate to ~1% available from literature. Our g-band PL relation is
similar to the B-band PL relation as reported in previous study. We applied our
PL and PW relations to anomalous Cepheids discovered in dwarf galaxy Crater II,
and found a larger but consistent distance modulus than the recent measurements
based on RR Lyrae. Our calibrations of gri-band PL and PW relations, even
though less precise due to small number of anomalous Cepheids, will be useful
for distance measurements to dwarf galaxies.
