Conditions and Indications
If an input level is below 0.4% of the rated range, the reading
becomes "0 V".
If an input level is below 0.4% of the rated range, the reading
becomes "0 A".
If an input level is 0.17% or less of the rated range, the
reading becomes "0 W".
If an input level is 0.17% or less of the rated range, the
reading becomes "0 Var".
If an input level is 0.17% or less of the rated range, the
reading becomes "0 VA".
If power input is 0.17% or less of the rated range, integration
stops.
If reactive power input is 0.17% or less of the rated range,
integration stops.
If the input level of either voltage or current is below 0.4% of
the rated range, "----" appears.
If frequency is 40 Hz or less or if the input level of a frequency
source is 10% or less of the rated range, the fixed clock is
selected, displaying the set fixed-clock frequency.
If power input is 0.17% or less of the rated range, integration
stops.
If power demand is 0.17% or less of the rated range, the
reading becomes "0 W".
If reactive power demand is 0.17% or less of the rated range,
the reading becomes "0 Var".
If an input level is below 0.4% of the rated range, the reading
becomes "0 V".
