Latching: Selects whether the output is latching or non-latching when Output 2
is an alarm. Latching alarms must be cleared before the alarm output will reset.
Non-latching automatically resets the alarm output when the condition clears.
The range is LAt or nLA, default is nLA. This only appears if the Ot2 = AL.
Silencing: Selects alarms silencing (alarm inhibit). Appears only when
ALt = dE. If LAt, press the Auto/Man key to reset the alarm output. If nLA, alarm
automatically resets 5 seconds after power is applied.
RTD: Selects the RTD calibration curve. JIS = 0.003916 / PC
