3-5-2. Control output signals
This becomes ON if the load cell input exceeds the ±3.2mV/V
range.
This becomes ON if the load cell input exceeds the maxi-
mum display value.
This becomes ON when a measurement is completed and
the next measurement is possible.
Band judgment output
This outputs band judgments.
This outputs continuous judgments and multi-zone
judgments.

o The control input signal is isolated from the unit's circuits by
a photocoupler.
o Signals are input to each terminal by shorting and opening
them with 19 and 20 COM.
A current of about 20 mA results from shorting.
When using a transistor, select one with a resistance of
at least 10 V and elements that allow the flow of at least
o You can confirm the status of input and output signals on
the screen shown in "5-3-6. TEST & INFO" on page 70.
Conducting a forced reset when the unit is writing data to a
USB flash drive or SD card could cause data loss.
