1.Reading rate with internal trigger and 60 Hz power line frequency. See “reading rates” for more detail.

2.Normal Mode Rejection Ratio, at 50 or 60 Hz ±0.1%. The NMRR for 400 Hz ±0.1% is 85 dB in S rate and 35 dB in M rate.

3.Common Mode Rejection Ratio at 50 or 60 Hz ±0.1%, with 1 kΩ in series with either lead. The CMRR is >140 dB at dc for all reading rates.

4.20 volts or 2 times full scale whichever is greater, not to exceed 1000V.

5.Reading rate-1/3 rdg / sec. in the 20 mV, 20Ω, 200 mA dc ranges

6.Reading rate-1.25 rdg / sec. in the 20 mV, 20Ω, 200 mA dc ranges
