※Only 
(preset output mode) setting is available in MT4Y-☐-43 (relay (low out)+transmission (DC4-20mA) output) and MT4Y-☐-43 (relay (low out)+transmission (DC4-20mA) output) models.
※To measure the current over DC5A, please select DV type because the shunt should be used.
※In case of selecting frequency display, no output will be provided even if it is output support models.(main output, sub output and RS485 communication output)
※The weight includes packaging. The weight in parenthesis is for unit only.
※Environment resistance is rated at no freezing or condensation.
