■ Scaling Example Using Range A
Indicated on the K3HB-V as 0 to 49N in the load cell specifications
(rated load 49N, recommended applied voltage 10 V, rated output 2
mV/V) (See note.)
Display value
49 N
Note: 2 mV/V indicates a load cell output of 2 mV for 1 V applied volt-
age for the rated load (when using a load of 1 N). When the ap-
plied voltage is 10 V, the load cell output is 20 mV (2 mV × 10).
