5. Load Cell Interface

It can be connected with 6x350Ω analog load cells (around 58Ω minimum resistance), to confirm the range of the load cells, the total resistance (TSR) can be calculated with the formula as below:

$$ \text { TSR } = \frac {\text { Input resistance } (\Omega)}{\text { Load cell numbers }} $$

Before connecting the load cells, make sure the TSR is above 58 , if it's less, the indicator can't work. Besides this, the cable distance must be considered, too, below is the maximum distance suggested:

TSR (Ω)	24# cable (m)	20# cable (m)	16# cable (m)
350	243	610	1219
58 (6-350 Ω)	40	122	224
