Temperature Measurement Settings
1 Select a channel (CH 1 to CH 10) for the

Do not detect broken (disconnected)
wires.
Normally when the thermocouple is dis-
connected, the value will fluctuate, etc.
a
nd 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
5
0
Hz or 60 Hz digital filter is enabled.)
When the wires are disconnected,
“OVE
R”
will be displayed as the measure-
ment value.
Int
Use the Memory HiLogger’s internal com-
pensation. Measurement accuracy is the
su
m of
the temperature measurement ac-
curacy and the RJC accuracy.
Ext Use an external RJC method instead of
th
e Memory HiLogger’s internal compen-
sation. Memory HiLogger measurement
a
ccuracy
is equivalent to the temperature
measurement accuracy.
