One hour warm-up and a fixed configuration with slow AC filter, sine wave input, and 6½ digits. 
Temperature within ±5 °C of temperature at calibration (Tcal between 18-28 °C).
[2]
90 minute warm-up and a fixed configuration and 6½ digits. Temperature within ±1 °C of temperature 
at calibration (Tcal between 18-28 °C).

Relative to calibration standards
[4]
20% over range on all ranges except 300VDC and AC ranges and 1 ADC and AC current ranges
[5]
For sine wave input > 5% of range. For inputs from 1% to 5% of range and < 50 kHz add 0.1% of range 
additional error. For AC filter slow.
[6]
Typically 30% of reading error at 1 MHz, limited to 1 x 10
