Judging Measurement Results
3.3.2 Judging with Upper and Lower Limit Values (Comparator
Judgment Mode)
This mode judges if the measurement results are within the specified range.
The comparator judgment allows you to do the following.
• Preset a judgment reference with reference value, upper and lower limit values, and display the
judgment result as HI (higher than the upper limit value), IN (within the range set for the upper
and lower limit values), or LO (lower than the lower limit value).
• Output the judgment results to an external device (via the EXT I/O connector).
• Judges up to four parameters with different settings.
• Beeps to notify judgment results.
Refer to “3.3.1 Setting the Judgment Mode” (p. 44).
HI Measured value > upper limit
IN Upper limit value ≥ measured value ≥ lower
limit value
LO Measured value < lower limit
- - - If reference standards have not been set

• Outside the guaranteed accuracy range (Judgment for a value
outside the guaranteed accuracy range is NOT )

• If measured values are outside the guaranteed accuracy range ( REF VAL ), judgment is
performed in order of judgment when the setting of [JUDGE EXEC] is DO . If NOT , judgment is
not performed and HI judgment is returned.
• There is no comparison performed to check if the upper limit value is greater than the lower limit
value, hence an error message will not be displayed if the setting of the upper limit value and
lower limit value are reversed.
