Outside Load: 0-
500Ω
Connection:
Outside connection: 4~20mA
analog input + port connected to “1” pin of DB9
analog input - port connect with “6” pin of DB9.
Testing :
Connect the 4~20mA to the analog input module, then read the value of 4~20mA at analog input
channel of an external computer.
If you do not have ananalog input module, adjust a multimeter to the current stalls, series connection
with the 4~20mA.
During Calibration
1.
Press[
] and [
] go to C32.
2.
Show[out-4], the output current should be 4mA.
3.
When you press [ ]show[out-5]
，
Pres[ ]show[out-20]
，
the output current should be 20mA.
4.
Adjust the current as needed, for example, adjust to [out-20], Press [ ] or [ ] to adjust the
current.
Digital I/O Function instructions:
4~20mA corresponds to Zero ~Max. capacity. After pressing ” TARE”, the weight will start from 4mA. Set
C31=0, 0~20mA output mode; C31=1 4~20mA output mode.
If you need 0~5V output, Set C31=0, then connect 250Ω at the two ends of current output, that will get
5 voltage at resistance two ends.
Relay output function (optional)
The indicator can be equipped with up to four optional relays that can be used to control external
equipment based on data gathered by the indicator. This can include controlling actions caused by
weight, piece count, upper or lower weight limits, or other data points that the indicator can identify.
If equipped, these functions are controlled through the C33 menu, as described below.
