[1] Specifications are for 1 hr warm-up and 6½ digits, Slow ac filter
[2] Relative to calibration standards
[3] 20% over range on all ranges except 300 Vdc and ac ranges and 1 Adc
and ac current ranges
[4] For sinewave input > 5% of range� For inputs from 1% to 5% of range
and < 50 kHz, add 0�1% of range additional error
[5] Typically 30% of reading error at 1 MHz, limited to 1 x 108 V Hz
[6] Specifications are for 4- wire ohms function or 2-wire ohms using scaling
to remove the offset. Without scaling, add 4 Ω additional error in 2-wire
Ohms function
[7] Input > 100 mV� For 10 mV to 100 mV inputs multiply % of reading error x 10
[8] Specified only for inputs >10 mA
[9] For total measurement accuracy, add temperature probe error
[10] Thermocouple specifications not guaranteed when 34907A module
is present� For < 1°C accuracy, a precision external reference is required�
