Alarm judgment and recording function
6.5.3 General Specifications
Alarm judgment is made at every sampling, and the history will be recorded in flash memory if the measured
value recording function remains active.
Judgment method Criterion threshold can be set to either Hi or Lo.
The instantaneous value at every sampling is judged (effective in any measurement
mode.).
Recorded data One data set contains time, generation/reversion, CH and judgment threshold.
Alarm output Alarm output × 2 CH

Output is turned ON when an alarm (Hi or Lo) occurs.
Whether to hold the alarm output can be selected. The reset switch or a command
can be used to reset alarms.
Clock accuracy ±100 ppm (Reference value at temperature from 0 to 50°C (32 to 122°F) without the
communications module)
Backup Recorded data (saved in flash memory)

Data loss for up to 2 minutes before and after a power outage may occur.
