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 greater
than 1 ΜΩ. If the input impedance is low, the output accuracy will be reduced due to
the internally provided resistance of 560 Ω.
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 and
scale value (gain) instead.
• Analog output = (Measured data - Reference value) x Scale value (gain)
For detail refer to Section 4.5.3.4 “F3: Setting the reference value”.
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.
4. This analog output will take place as associated with program numbers 5 through
9 during simultaneous measurement. Output associated with program numbers 0
through 4 will be available through the standard Analog I/O interface.
