(1) In case that the external control terminal of the comparator is AUTO. (outputting
comparator results)
Comparator results (Hi, IN, Lo) and result data of measurements (BCD) are
output when EOC becomes 1 after measurement is completed.
Comparator results and measurement data should be taken after EOC
becomes 1 (at the signal’s rising edge).
Depending on how the circuit is connected and the signal is loaded, with open
collector outputs, variations in the interval between signal output and signal
detection can prevent detection from taking place as indicated in the
illustration above. In particular, open collector outputs and BCD signals
should be loaded only after waiting about 1 ms following detection of the EOC
signal.
(2) In case that the external control terminal of the comparator is EXT. (outputting
comparator results)
In the manual mode, comparator results (Hi, IN, Lo) are output only when the
MANU
―――――――
signal becomes 1. Measurement data (BCD) is output continuously.
(3) Output during current abnormalities
When a current abnormality occurs (when the resistance being measured is
unchucked), the NG signal becomes 0.
