Operating Characteristics
TEMPERATURE COEFFICIENT ...........<“(0.0006% of reading + 0.3 Count) per °C from 0°C to 18°C
MAXIMUM INPUT...................................1000V dc or peak ac on any range.
NOISE REJECTION................................Automatically optimized at power-up for 50, 60, or 400 Hz.
RATE

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
