disconnection
detection
Can be switched between disconnection detection check ON and
OFF for each recording interval during thermocouple measurement.
Detection current 5 μA ± 20%, no current while measurement data
is acquired.
(Disconnection detection cannot be set at recording interval of 0.1
seconds.)

function
Alarm
Displays
[ALARM]
when the value is outside of the setting range.
Lit:
The current measurement value is outside the range.
Blinking: There was a value that was outside the range but the
current value is in the range.
Scaling
Scales and displays a measurement value.
(The lamp turns off if a unit other than the allowable display unit is
set during scaling.)
Recording operation
hold function
Automatically recovers records after the power is recovered if the
power is shut off during recording.
(The data during power shutdown will not be recorded.)
Erroneous operation
prevention function
Displays a confirmation message when recording starts/stops, or
the power is turned off.
Whether a confirmation message is displayed can be selected.
