･ It is only possible to select from the combinations shown in the connection
setting screen.
For combinations 1P3W and above, adjacent units must be of the same type.
･ When using the 9602
AC/DC CLAMP INPUT UNIT
, only a combination of the
same current sensor type can be selected. In other cases, all are set to 1P2W.
･ When using the 9602
AC/DC CLAMP INPUT UNIT
, if the sensor
configuration is changed (including with the sensor not connected), and the
unit is then powered on, "Resetting due to configuration change." is
displayed. Pressing
F1
(YES) resets settings. Pressing
F2
(NO) does not
reset and settings remain unchanged, but the display value for current may
be changed. Return the configuration settings and power on again. The
message is not displayed.
･ When using clamp-on units, if the sensor rating is changed and the unit is
then powered on, in the 1P2W mode the CT ratio within the unit is
automatically set accordingly. For combinations 1P3W and above, if other
channels in the combination have different ratings the combination is
disabled for measurement.
･ The display items in the various modes are as follows.
・
Although the display will show for each channel
3P3W
or
3V3A
the active
power (
P1, P2 and P3
), reactive power (
Q1, Q2 and Q3
), apparent power
(
S1, S2 and S3
), power factor (
λ
1,
λ
2 and
λ
3
), and phase angle (
φ
1,
φ
2
and
φ
3
), please be aware that these figures have no meaning.
･
Power factor (
λ
) and phase angle (
φ
) are not be displayed simultaneously.
･
The measurement values for three-phase three-wire in 3P3W and 3V3A mode
are same because of same measurement method.
