Judging Measured Values
This chapter describes how to set judgment standards and perform comparator measurement
(p. 53) or BIN measurement (p. 57). This functionality automatically compares measured
values to the reference values and generates judgment results, making it convenient for tasks such
as sorting (classifying) measurement targets or conducting shipping inspections.
Comparator measurement and BIN measurement provide the following capabilities:
Displayingjudgmentresultsonthescreen
Soundingthebuzzer
(comparatormeasurementonly)
“Displaying trends, bar graphs, statistics, and
judgment results” (p. 43)
“To check judgments aurally” (p. 55)
(By default, the buzzer is disabled.)
Outputtingjudgmentresults
“9 Outputting Data” (p. 111)
Enablingtheabsolutevaluejudgmentfunction
When measuring batteries, the sign of the voltage
reading depends on the orientation of the battery’s
electrodes. Consequently, it is necessary to repeat
measurement when the battery’s orientation is
changed.
The DM7275/DM7276 provides an absolute value
judgment function that, when enabled, makes it
possible to perform comparator measurement
or BIN measurement while ignoring the sign of
measured values.
See “4.1 To Obtain Accurate Judgments Even When
the Polarity of the Measurement Target (Battery,
etc.) Is Reversed” (p. 52)
Comparator measurement and BIN measurement use the same judgment method in which
measured values are compared to previously set upper limit and lower limit values. It is also
possible to set only an upper limit value or a lower limit value.
Upper limit and lower limit values
Upper limit
HI
IN
Lower limit
LO
When (lower limit value ≤ measured
value ≤ upper limit value), the
instrument will generate an IN
judgment
.
Upperlimitvalueonly
Upper limit
HI
IN
When (measured value ≤ upper limit
value), the instrument will generate
an IN judgment, including in the
event of an over-range (-OvrRng).
Lowerlimitvalueonly
Lower limit
IN
LO
When (measured value ≥ lower limit
value), the instrument will generate
an IN judgment, including in the
event of an over-range (+OvrRng).
• Comparator measurement and BIN measurement cannot be performed simultaneously. When
one is set to ON, the other will be automatically set to OFF.
• The lower limit value cannot be greater than the upper limit value. The instrument will display
ERR:001 if you attempt to set such a value.
• When both the upper limit value and lower limit value are set to OFF, IN judgment will be
performed.
