Measurement Preparations
3.7 Using a Clamp-On Sensor (Option)
37
This instrument supports voltage-output type clamp-on sensors.
The clamp-on sensor should provided about 0.5V rms output for
full-scale current measurement.
• To use Model 9661, 9660, 9694, 9669 and 9667 Clamp-On Sen-
sors, select the model name displayed in the instrumentÅfs
clamp sensor settings.
• To use the Model 9695-02 CLAMP ON SENSOR, set the clamp-
on sensor setting to "10 mV/A".
• To use the Model 9695-03 CLAMP ON SENSOR, set the clamp-
on sensor setting to "9660".
• The Model 9657-10 and 9675 CLAMP ON LEAK SENSOR can
be used with this instrument. Set the clamp-on sensor setting to
"100 mV/A".
3.7 Using a Clamp-On Sensor (Option)
Connect the clamp-on sensor to the instrument first, and
then clamp around the line to be measured.
Observe the following to avoid electric shock and short cir-
cuits.
• The clamp sensor should only be connected to the second-
ary side of a breaker, so the breaker can prevent an acci-
dent if a short circuit occurs. Connections should never be
made to the primary side of a breaker, because unrestricted
current flow could cause a serious accident if a short cir-
cuit occurs.
• When the clamp sensor is opened, do not allow the metal
part of the clamp to touch any exposed metal, or to short
between two lines, and do not use over bare conductors.
• To prevent damage to the instrument and sensor, never
connect or disconnect a sensor while the power is on, or
while the sensor is clamped around a conductor.
