Notes:
1 Input impedance is in parallel with capacitance < 120 pF.
2 Use Rel operation.
3 In VDC 1000 V range, 5% over-range (1050 VDC) is readable.
4 Typical at full scale reading and voltage across the input terminals.
5 Use Rel operation. If Rel operation is not used, add 0.2 W additional error.
6 In order to eliminate the noise interference, which might be induced to the test leads, it is recommended to use a shielded
test cable for measuring resistance above 100 kW
