Item Description

Zero offset* Offsets the tare weight of load cell outputs automatically and adjusts the load cell output value for the case of the maximum weighing capacity automatically to the optimum value within an input range.

Gravitational acceleration compensation function*

Corrects gravitational errors caused by the difference of gravitational acceleration in each region when the places of the calibrated weigh scale and the installed weigh scale are different.When installing and calibrating the weigh scale at a same place, the setting is not required.

Two-point calibration function*Adjusts the Q61LD to work with load cells. For using the Q61LD as a weigh scale,Adjusts the Q61LD to make the gross weight output value be accurate, when an actual load is placed.

Weight conversion method

Executes one of the following processing for gross weight output values and digital output values, resulting in averaging unbalanced output values.(1) Sampling processing(2) Count average processing(3) Moving average processing(4) Combination use of count average and moving average

Zero tracking function The zero tracking function is the function that automatically corrects a slow zero drift, in other words, corrects a subtle variation of the zero point. Time and a variation range determine the zero tracking function.Performs a zero point adjustment of a weigh scale.Adjusts the zero point when the zero point moves after two-point calibration of the weigh scale is performed.Zero set/reset function

Input signal error detection function

(1) If a gross weight output value exceeds the ninth scales, the bit corresponding to Excess of weighing capacity (1) of the input signal error detection flag will be turned on.

(2) If the zero set of gross weight output values exceeding the zero point adjustment range is executed, the bit corresponding to Outside the zero point range (1) will be turned on.

(3) If a gross weight output value exceeds the given upper limit range, the bit corresponding to Input signal error (1) will be turned on.

(4) If an analog input (load cell output) that exceeds the conversion range during the two-point calibration mode, the bit corresponding to Excess of input values to be converted (1) will be turned on.

Warning output functionDetermines the upper limit and lower limit values of gross weight output values.(1) Lower limit: Determines the status of "Gross weight output value Gross weight lower lower limit value".(2) Upper limit: Determines the status of "Gross weight output value Gross weight upper upper limit value".

1/4 scale function Detects a mid-value of scales of gross weight output values.Divides a minimum division in quarters and turns on Center point status (X2) if the mid-value is within the setting range.

Stable status If the changed value of a gross weight output value has been within the setting value and the status has remained for the setting time or longer, Stable status (X1) will be turned on. The stable status is set with the variation range and time.

Maximum and minimum values hold function Stores the maximum and minimum values of gross weight output values and digital output values into the Q61LD.

Output value hold function Holds a gross weight output value and digital output values temporarily.The output value does not change during the hold regardless of the change of load cell output signals.

* These functions are saved to the nonvolatile memory (FeRAM) of the Q61LD, thereby, the data will not be cleared even when the Q61LD is powered off.
