Digital multimeter specifications
– Accuracy is given as ± (% of reading + counts of least significant digit) at 23 ± 5 °C, with relative humidity < 80 RH.
– AC V specifications are AC coupled, true RMS and are valid from 5% to 100% of range.
– Temperature coefficient is given as 0.1 × (specified accuracy) / °C (from 0 to 18 °C or 28 to 50 °C).
– Common mode rejection ratio (CMRR) is > 90 dB at DC, 50/60 Hz ± 0.1% (1 kΩ unbalanced).
– Normal mode rejection ratio (NMRR) is > 60 dB at 50/60 Hz ± 0.1%.
Maximum reading 10,000 counts with automatic polarity indication

1. Only allowed to measure up to CAT III 600 V if referring to GND.
2. In an open connection, the reading shown on the display is noise pickup due to the high input impedance at the input terminal.
3. Only allowed for oating voltage
4. Denotes typical speciations, all others are warranted.
5. Denotes characteristics.
6. The accuracy is specied after the Null function is used to subtract the test lead resistance and thermal effect.
7. RH is specied for < 60%. The temperature coefcient is 0.15 × specied accuracy as > 50 MΩ.
8. The accuracy is based on lm capacitors or better and uses the Relative mode for residual values.
NOTE: Keysight recommends using the U1586B temperature adapter for temperature measurement.
