4.5.2 Function Specifications
Execute the functions from the PC application via communications.
Monitoring function
Measured value recording function
Alarm judgment and recording function
4.5.3 General Specifications
This function outputs the current measured values (instantaneous values).
Measurements are recorded at a set recording interval.
Real-time manage-
ment This is automatically set from the PC application at the start of recording.
Recording start Immediate start/Reserved-time start
Recording end Manual end/Reserved-time end
Operation when
memory is full Memory full stop /Endless

Set the condition before the start of recording.
Recording interval 1/2/5/10/15/20/30 sec., 1/2/5/10/15/20/30/60 min.
Recording mode Instantaneous value recording mode (Total during the interval)
Recorded data One data set contains time, recording data (for 2 channels).
Recording capacity 512 k bytes Flash memory
Quantity of recorded
data Instantaneous value recording mode: 30,000 data × 2 CH
Power outage
protection After recovering from a power outage, the instrument automatically returns to the state
held before the outage.
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.
Hi: The total at every sampling is judged within the interval.
Lo: The total is judged at every interval.
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 without the communica-
tions module)
Backup Recorded data (saved in flash memory)

Data loss for up to 2 minutes before and after a power outage may occur.
