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 instrument’s internal compensa-
tion. This setting is made when a thermo-
couple (or compensating lead wire) is
connected directly to the instrument. Mea-
surement accuracy is the sum of the tem-
perature measurement accuracy and the
RJC accuracy.
Ext Use an external RJC method (0°C ice wa-
ter, etc.) instead of the instrument’s inter-
nal compensation. The instrument’s
measurement accuracy is equivalent to
the temperature measurement accuracy.
