ANALOG OUT(4~20mA) INTERFACE
This option transmits the indicated weight value to external devices (Recoder, P.L.C Central
Control Room, etc.) that is adjusted by the Analog Signals via Current Out.

When the indicated weight is O, the output current will be 4mA, and when the indicated ▶
weight is at full capacity, the output current will be 20mA.
Lo( ▶ -) Terminal is not GND. Therefore, it must not be connected to GND Line, Body GND
or other similar devices of other equipment.

1. The default value of the unit is 4mA when the indicated weight is O, and 20mA when it is at the
maximum load.
2. If you wish to adjust the output value range, adjust F70 and F71.
3. When using the DIGITAL MULTI-METER to measure the output voltage does not allow accurate
output, fine-tune VR (Zero), VR (SPAN) on ANALOG OUT PCB in the interior side of the Indicator.

※
Warning: This ANALOG OUTPUT outputs the ANALOG value converted from
the indicated weight value (MICRO PROCESS DATA) by the D/A CONVERTER.
Also, please note that as the D/A CONVERTER’s precision rate is
under 1/4000, it is not suitable for devices requiring more than
1/3000 precision rate.
