CAUTION
- If you will connect directly to the device under test (DUT), set the pi-circuit setting to ON. Failing
to do so may prevent normal measurements from being performed. Use Device Manager to set the
pi-circuit setting to ON or OFF.
- Accurate measurements may not be possible if this product and the device under test (DUT) are
affected by noise or if there is a large distance between this product and the device under test
(DUT).
- An uncertain signal may be generated from the OUT terminal immediately after the computer starts
(for a few seconds after the power turns on).
