(7) Faulty Measurement Detection
Out-of-Range Detection Function
Operation Indicates under- or over-range values in the following conditions:
•
Measurement value is outside of the measurement range
•
The relative calculation value is outside of the display range
•
Measurement value is outside of the A/D converter input range
•
The zero-adjusted value is outside of the display range
Ex.: Zero-adjustment in the 1
Ω range with 0.5 Ω zero-adjustment in effect, measur-
ing 0.1
Ω
gives a calculation result of -0.4
Ω
, which is outside of the display range.
Contact Check Function
Operation Checks the connections between H
POT
and H
CUR
, and between L
POT
and L
CUR
