10.4 Accuracy
260
*
1: Measurement (including cable capacity) between T1 and T2 in leakage current between
enclosure and enclosure mode
*
2: Including voltmeter (1 M load) at network output section Input protective fuse is short-cir-
cuited.
*
3: Network A (filter OFF), Network B1, B2 (filter OFF),Same circuit for network E
*
4: -15 dB points for network C (filter ON1, ON2 )
*
5: 0.1 Hz only at Network B2. Other Network from 15 Hz.
*
6: Impedance theoretical values do not include the network output unit voltmeter (1 M load)
