6. INTERFACE UNIT
6.2.2.4 Analog output
Measurement results will be outputted as full-scale ±5V analog signals.
LSM has two analog outputs. First is standard analog I/O interface. Second is this optional
2
nd
Analog I/O interface.

ALG
a. Range of analog output voltage is ±5V.
b. The accuracy of the analog output voltage is 0.2% of its full scale.
c. This analog output must be connected to a device that has an input impedance of 1 ΜΩ
or greater. If the input impedance is low, the output accuracy will be reduced.
2) Method of use
• Set a proper reference value and scale value in the function setup. However, if “Copying
the target value to the reference value” is set in the basic setup, set the target value instead
of reference value.
• (Analog output) = (Measured data) - (Reference value) x (gain)
For detail refer to Section 4.5.3.4 “F3: Setting the reference value”.
• In the normal measurement mode, first and second analog output is same output data.
• In the simultaneous mode, the analog output of program Px0 to Px4 will be made via the
first, and that of program Px5 to Px9 will be made via the second.
• Set the analog output voltage in the event of Err-0 by the basic setup (“1 ERR-0V”).
NOTE 1. Always use a braided shielding wire cable as the analog cable, and positively
ground the braided shielding wire to the FG terminal.
2. If wiring the Analog output connector, do not directly touch the output terminals by
hand, which has static charges, because the internal circuit may be damaged by
static discharge. Discharge the static energy by touching the metallic surface of
the Display unit in advance. In addition, unplug the power cord from the outlet
before commencing wiring.
3. After wiring has been completed, close the protective cover.
