Caution When Using Remote Scale
To count with an accurate unit weight, register the unit weight with a sample by using the main scale and
perform ACAI. Then, switch to the remote scale.
Perform tare subtraction with the main scale and remote scale respectively.
When using a remote scale, if the unit weight is registered with the main scale and then it is switched to a
remote scale, ACAI does not work. The opposite is also same.
Required Specifications of Remote Scale
A weighing platform with up to four 350
Ω
load cells can be connected.
The range of the remote scale’s weighing capacity is from 0.001 kg to 500000 kg.
When weighing capacity/minimum display exceeding 1/10000 are set, internal sensitivity per 1 d is
reduced.
Output from the weighing platform should be within the range of ± 1.0 to ± 3.5 mV/V when loading up to
weighing capacity. The power source of load cell is 5 V.
Input sensitivity of load cell
Input sensitivity “X” of the load cell is as follows, given that rated output of the load cell is “A”, its capacity is
“B”, and minimum display is “D”.
X =
5[𝑉𝑉] × 𝐴𝐴 × 𝐷𝐷
𝐵𝐵
× 1000[𝜇𝜇𝑉𝑉]
Make input sensitivity “X” of the load cell to be 0.5 µV or greater.
With the example below, input sensitivity “X” of load cell is 1.5 µV.
- Rated output of load cell
A 3 mV/V
- Capacity of load cell
B 100 kg
- Minimum display
D 0.01 kg
To maintain good performance, keep the length of the load cell cable up to 5 m.
