[1] One hour warm-up and a fixed configuration
with slow AC filter, sine wave input, and 6 1 ⁄
2
digits. Temperature within ± 5°C of tempera-
ture at calibration (Tcal between 18-28°C).
[2] 90 minute warm-up and a fixed configuration
and 6 1 ⁄
2
digits. Temperature within ± 1°C of
temperature at calibration (Tcal between
18-28°C).
[3] 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 singe 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 8 volt-hertz
[7] For 4-wire ohms or 2-wire ohms using scaling
to remove offset. Add 4 ohms additional error
to 2-wire ohms function without scaling.
[8] Input > 100 mV. For 10 mV inputs multiply
% of reading error x 10. For 1 sec aperture.
[9] Specified only for inputs > 10 mA.
For AC filter slow.
