Program Selector Input
Terminals The desired program No. 1 to 5 can be selected from external equipment
using these terminals.
When terminal 5 (6, 7, 8, or 9) is grounded with terminal 10 for an instant,
program No. 1 (2, 3, 4, or 5) is selected and retrieved.
* When two or more terminals are grounded at the same time, the program
with the smallest number will be selected.
• When terminal 3 is grounded with terminal 4, the displayed and output
values are retained.
• When terminal 3 is disconnected from terminal 4, normal measurement is
resumed.
• When the LS controller is set to the P-P, PEAK, or BOTTOM mode, the
previous measured value is reset by grounding terminal 3 with terminal 4
and then disconnecting these terminals.

Terminals
Laser Emission Control Input
Terminals (LASER REMOTE) When terminals 11 and 12 are connected, the laser emission indicator LED
on the front panel lights. And, laser is emitted approx. 5 seconds after the
connection is made. When terminal 11 is disconnected form terminal 12, the
laser emission indicator LED goes out, and the laser emission stops.
The LS controller is delivered with a jumper inserted between terminals 11
and 12.

Output Specifications
Comparator Output
Terminals
Relay: SPST-NO contact, 250 VAC, 2 A (resistive load)
• HIGH OUT terminals: HI
Comparator output is sent through these terminals when the measured value
is above the upper tolerance limit.
• LOW OUT terminals: LO
Comparator output is sent through these terminals when the measured value
is below the lower tolerance limit.
• GO OUT terminals: GO
Comparator output is sent through these terminals when the measured value
is within the tolerance range.
Use a crimp contact for wiring as shown below. Be sure to use a cable with
at least 0.4-mm sheath.
