A&D HV-G Series instruction manual Comparator Function, Comparator Sign, Comparison Condition

11 Comparator Function

This function compares a display value with the upper limit (HI) and the lower limit (LO) and displays these results.

It is necessary to set the “comparator function (f6 0 ~ f6 7 )” parameters, upper limit value (HI) and lower limit value (LO) in the function table, in advance to use this function.

It is necessary to install option OP-03 or OP-04, if you use the relay output of the comparator.

Comparator Sign

Comparison results are displayed by indicators

Comparison Condition

weighing value < lower limit value	LO	is displayed and output.
lower limit value < weighing value < upper limit value	OK	is displayed and output.
upper limit value< weighing value	HI	is displayed and output.

Parameter List and Word Definition

The “ near-zero “ is within ±4 digits from the zero point in the unit of kg. The “digit” is a unit of display, and is equivalent to the minimum graduation. The “zero point” is the fundamental starting point to weighing.

Function table					Meaning and Purpose
f6	0	The scale always compares the current display value. Pressing the
		SET	switch turns the comparator on and off
f6	1	The scale always compares the display value.
f6	2	The scale always compares the display value if not near-zero. Press
		ing the			switch turns the comparator on and off
				SET
f6	3	The scale always compares the display value if not near-zero.
f6	4	When the display value becomes stable the scale compares the
		display value. Pressing the							switch turns the comparator on and off.
							SET
f6	5	When the display value is stable the scale compares the display
		value. It does not compare on an unstable condition.
f6	6	When the display value becomes stable, while not near-zero, the scale
		compares the display value. It does not compare on an unstable
		condition. Pressing the						switch turns the comparator on and off.
						SET
f6	7	When the display value becomes stable and not near-zero, the scale
		compares the value.
Caution

The upper limit value (HI) must be greater than the lower limit value (LO).

The parameters of the upper limit value (HI) and the final value (HI) use the same memory. The parameters of the lower limit value (LO) and the zero band (LO) use the same memory. The upper/lower comparator function, the simple batch function and the full/dribble batch function cannot be used at the same time because these parameters use common memory.
