[1] Speciﬁ cations are for 1 hr warm-up and 6½ digits, Slow ac ﬁ lter
[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 10

V Hz

[6] Speciﬁ cations 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] Speciﬁ ed only for inputs >10 mA
[9]

For total measurement accuracy, add temperature probe error

[10] Thermocouple

speciﬁ cations not guaranteed when 34907A module

is present. For < 1 °C accuracy, a precision external reference is required.
