[*1]Measurement of large diameter more than several meters can be made by using 2 units of Scanning Unit
[*2]Measuring accuracy is stated on the conditions of average time more than 400 times and measurement within special measuring area.
[*3]LDM-703, LDM-704A and LDM-705 are Model No. only for Swing Mechanisms.
[*4]These weights are only for Swing Mechanisms.

ADD-ONS
 Signal Extender(LDM-201, LDM202) - extends cables when the distance between a scanning unit and a display unit exceeds 30 metres.
Signal Distributor(LDM-205, LDM-206) - divides output signals from a scanning unit.
BCD Distributor(LDM-B2)
