Out-of-Range Detection Function
Operation Indicates under- or over-range values in the following conditions:
• Measured value is outside of the measurement range
• The relative calculation value is outside of the display range
• Measured value is outside of the A/D converter input range
• The zero-adjusted value is outside of the display range
Ex.: In the 1
range with 0.5 zero-adjustment in effect, measuring 0.1 pro-
vides a zero-adjusted value of -0.4 , which is outside of the display range.
Contact Check Function
Operation Checks the connections between H
