4.2.2 Selecting Ranges
• If the maximum voltage or current rating is exceeded, immediately stop mea-
suring, shut off power to the measurement lines, and disconnect from the mea-
surement object.
• Continuing to measure when maximum ratings are exceeded may damage the
instrument and result in injury or death.
• The maximum input voltage is 1500 V, ±2000 V peak. Do not use the voltage
exceeding it to avoid damaging the unit or injury.
• Never exceed the maximum rated input current to the current sensor, as dam-
age to the instrument or injury or death can result.
