Linearity: <0.1ppm of range typical, <0.2ppm maximum.
Zero Stability: Typical maximum variation in 1 hour, T
REF ± 0.5°C, 7H-digit resolution, 10-reading digital filter, synchronous autozero.

Polarity Reversal Error: This is the portion of the instrument error that is seen when HI and LO are reversed. This is not an additional error—it
is included in the overall instrument accuracy specification.
Reversal Error: <4 counts at 10V input at 7H digits, 10 power line cycles, synchronous autozero, 10-reading repeat digital filter.
Input Bias Current: <100pA at 25°C.
Settling Characteristics: <50µs to 10ppm of step size for the 200mV–20V ranges. <1ms to 10ppm of step size for the 200V and 1000V
ranges. Reading settling times are affected by source impedance and cable dielectric absorption characteristics.
Autoranging: Autoranges up at 105% of range, down at 10% of range.

Non-Repetitive Spikes: 10% of range per µs typical slew rate.
Spike Width: Specifications apply for spikes 1µs.
Range Control: In Multiple Display mode, voltage range is the same as DCV range.
Spikes Measurement Window: Default is 100ms per reading (settable from 0.1 to 9.9s in Primary Display mode).
Input Characteristics: Same as ACV input characteristics.
Spikes Display: Access as multiple display on DC Volts. First option presents positive peak spikes and highest spike since reset. Second
option presents negative spikes and lowest spike. Highest and lowest spike can be reset by pressing DCV function button. Third option
displays the maximum and minimum levels of the input signal. Spikes displays are also available through CONFIG-ACV-ACTYPE as primary
displays.

For on-scale readings, no trigger delays, internal trigger, digital filter off, normal autozero, display off, SREAL format. These rates are for 60Hz and (50Hz). Rates
for 400Hz equal those for 50Hz.
