Restrictions of measured data
F/W version is displayed in five seconds after the power loading to this device.
Measurement and communication do not performed in a few seconds after the configuration or the change of the rating to it.
Behaviors during operation are as follows:

Pulse count When use of upper / lower limit alarm = oFF or upper / lower limit alarm
element ≠ pulse count (upper limit), counting restarts from 0 when
999999 have been exceeded.
When use of upper / lower limit alarm = on and upper / lower limit alarm
element = pulse count (upper limit), it is fixed to 999999 when 999999
have been exceeded.

For contact input ON/OFF, integrated value may deviate up to 250 ms
less in time at the start or stop of integration.
Same as on the left
