194 1326B/E1411B Multimeter Specifications Appendix A
True RMS AC Voltage (AC coupled)
Crest Factor: 7 at 10% full scale; 1.5 at full scale
DC to 60 Hz common mode rejection (CMR)
64 V and 300 V range 50 dB
All other ranges 86 dB
DC to 400 Hz common mode rejection (CMR)
64 V and 300 V range 34 dB
All other ranges 70 dB
Conditions: CMR and Effective Common Mode Rejection (ECMR) measured with 1 kΩ in each of HIGH and LOW leads, 10%
imbalance. LOW connected to COMMON at source. Measured with respect to earth ground.
