Actions
Current (A)
Current
demand (DA)
0A when the input current is less than 0.005A
When it is over the upper limit of the possible
display range (9999), the upper limit of the
possible display range (9999) is displayed.
Voltage (V)
0V when the input voltage (line voltage) is less than11V.
For 3-phase 4-wire, 0V when the line to neutral voltage
is less than 11V or the line to line voltage is less than
19V.
For 1-phase 3-wire, 0V when the voltage between
P1-P3 is less than 22V.
When it is over the upper limit of the possible
display range (9999), the upper limit of the
possible display range (9999) is displayed.
(Note 2)
Active power (W)
Reactive power (var)
Apparent power (VA)
0W, 0var and 0VA for total when the current and the
voltage are 0A and 0V for all 3 phases.
0W, 0var and 0VA for each phase when the current of
phase n is 0A or the voltage of phase n is 0V.
(where n = 1,2 or 3)
When it is over the upper limit of the possible
display range (9999), the upper limit of the
possible display range (9999) is displayed.
Power factor (PF)
1.0 for total when the current and the voltage are 0A and 0V for all 3 phases.
1.0 for each phase when the current of phase n is 0A or the voltage of phase n is 0V. (where n = 1,2 or 3)
Frequency (Hz)
When the voltage of phase1 is 0V, ---- is displayed.
(Note 3)
When the frequency is less than 44.5Hz or
over 99.9Hz, ---- is displayed.
Harmonic current
(HI)
For effective value measurement
: When the voltage of phase1 is 0V, 0A is displayed.
: When the frequency is less than 44.5Hz,
---- is displayed for all phases.
For content factor measurement
: When the 1st current harmonic is 0A, 0A is
displayed. (Each phase)
: When the voltage of phase1 is 0V, 0% is
displayed.
: When the frequency is less than 44.5Hz,
---- is displayed for all phases.
Harmonic Voltage
(HV)
For effective value measurement
: When the voltage of one phase is 0V, ---- is displayed.
: When the voltage is 0V, 0V is displayed. (Each phase)
: When the frequency is less than 44.5Hz,
---- is displayed for all phases.
For content factor measurement
: When the voltage of one phase is 0V, ---- is
displayed.
: When the voltage is 0V, 0% is displayed.
(Each phase)
: When the frequency is less than 44.5Hz,
---- is displayed for all phases.
Operating Time
999999 hour is displayed if it is over 999999.
Note1: Input current and input voltage means the input to the instrument. They are not to primary sides of VT, CT.
Note2: For direct measurement, it does not input upper maximum scale value.
Note3: Depending on the setting, “----“ is displayed when the voltage of phase 1 is not 0V.
