1-4. Instructions for connecting to

the measuring unit

• The LT20 is a display unit designed for DG and DL series
measuring probes with mini DIN type connectors.
• Set the input resolution of the display unit to match the
resolution of the measuring probe. Measuring may not be
performed correctly if the resolutions do not match. The
input resolution is set by the initial settings.
(See "5-1. Initial settings" P.52.)
• When the measuring range of the connected probe is 100
mm or more and the display resolution is set on 0.0005
mm, not all the measuring ranges can be displayed. (The
highest rank figure becomes the "F" display which means
an overflow) Therefore, set a display resolution on or
below 0.001 mm.
