
Do not detect broken (disconnected)
wires.
Normally when the thermocouple is dis-
connected, the value will fluctuate, etc.
and will not be stable.
On Detect broken wires.
(This setting is available only when the re-
cording interval is at least 100 ms, and the
50 Hz or 60 Hz digital filter is enabled.)
When the wires are disconnected,
“OVER” will be displayed as the measure-
ment value.
Int

Use the Memory HiLogger’s internal com-
pensation. Measurement accuracy is the
sum of the temperature measurement ac-
curacy and the RJC accuracy.
Ext Use an external RJC method instead of
the Memory HiLogger’s internal compen-
sation. Memory HiLogger measurement
accuracy is equivalent to the temperature
measurement accuracy.
