NOTE
When measuring current with the input coupling set to CLAMP,
if the range of the product and the current range of the clamp do
not match, incorrect numeric values are displayed. The same
range must be set on both devices for proper measurement.
The voltage output of a 9018-10, 9132-10 CLAMP ON PROBE
is 0.2V AC full scale for the selected range (for the 10A range,
0.2V AC is output with 10A input).
If a particular scaling value is desired, set the input coupling to
DC to enable setting on the Scaling Screen. Refer to Section 7.5
Scaling function for details.
The clamp measurement scaling settings are enabled when the
input coupling is set to CLAMP, but when the coupling is
returned to DC the previous scaling settings are recalled.
When the 9018-10, 9132-10 is used to measure
current waveforms
When the 9018-10, 9132-10 is connected, the input
coupling is set to CLAMP and the product and 9018-10,
9132-10 are set to the same measurement range, signals
from the sensor are scaled automatically and the current
value can be displayed and recorded.
The example shows the 9018 with current range set to 10A.
When changing the current range of the probe, change the
range of the product to match.
