• If measuring a voltage of 900 V or more, add the following value to the accuracy gures for voltage and active
power.
±
0.02% of reading
Even when the voltage input values decreases, the eect of self-heating persists until the input resistance
temperature falls.
• If the DC voltage is between 1000 V (exclusive) and 1500 V (inclusive), add 0.045% of reading to accuracy
gures of voltage and eective power. Values of the measurement accuracy are only designed values.
(When the DC voltage is between 1000 V (exclusive) and 1500 V (inclusive), accuracy for DC voltage and DC
eective power is guaranteed after custom-ordered calibration made by Hioki.)
