5.2.9 Setting the Clamp-On Sensor (page 67)
The table below lists the wiring check items and criteria.
Pressing the
I Range
key repeatedly changes the range for the cir-
cuit on the screen as follows:
When using the
9660/9695-03:
"5 A"→"10 A"→"50 A"→"100 A"
When using the
9661:
"5 A"→"10 A"→"50 A"→"100 A"→"500 A"
When using the
9667: 5000/500-A
range
"5 kA"/ "500 A" fixed
When using the
9669:
"100 A"→"200 A"→"1 kA"
When using the
9694:
"500 mA"→"1 A"→"5 A"
When using the
9695-02:
"500 mA"→"1 A"→"5 A"→"10 A"→"50 A"
Wiring Check Item Criteria
Voltage input NG when input is less than 10% of the voltage
range
Current input (except
for I4 when 3P4W4I is
selected)
NG when input is less than 1% of the current
range
Phase difference (cur-
rent - voltage)
NG when each current is not within ±60 de-
grees with respect to the voltage of each phase
Voltage phase
1P3W: NG when U2 is not within 180
degrees
±
10 degrees with respect to U1
3P3W2M: NG when the phase lead of U2
is not within 60 degrees
±
10 degrees with
respect to U1
3P3W3M, 3P4W, 3P4W4I: NG when the phase
lag of U2 is not within 120 degrees ±10 de-
grees with respect to U1, or when the phase
lead of U3 is not within 120 degrees ±10 de-
grees with respect to U1
Current phase (for
three-phase lines only)
NG when current phase sequence is negative
Voltage balance (ex-
cept for 1P2W)
NG when one voltage is 70% or less than the
other voltage
