Page 14: Connecting Load Cell Cable
Load Cell Terminal Connections Two types of load cell connection are available: 6-wire connection and 4-wire connection. For high precision and stable weighing, 6-wire connection is recommended. Terminal No. -
Page 15: Verifying Load Cell Cable
If the 4-wire connection has to be used, please take the following measures. Be sure to connect terminals EXC+(6) and SEN+( 5 ) and terminals SEN-(4) and EXC-(3). When lengthening the load cell cable, try to use cable with a large cross-sectional area. -

The Tare Function Tare is a function to store the gross weight as the tare value and set the net weight to zero. It is performed by pressing the key. (TARE) The tare weight is stored in the non-volatile memory and is maintained, even if the power is disconnected. -

The value will be refreshed if it increases again. Averaging hold This function averages weighing data over a certain period of time and then holds the result. It is useful for measuring things that are difficult to weigh such as an animal that won’t settle down, or for averaging out the weight of an object in an unstable state. -

Page 25: Digital Linearization
It is possible to input up to four points in addition to the zero point. The zero point and each input point will be corrected to put them in a straight line. Areas between input points that could not be corrected completely with straight line correction or with secondary correction will be corrected using a curved line derived from high-order equations. -
