Switching
For test applications that don’t
require the built-in measurements
of the 34970A, the unit can be
ordered without the internal DMM.
This provides an ultra low-cost
solution for routing test signals to
and from your device-under-test
and assorted instruments, including
external DMMs, scopes, counters
and power supplies. Plus, you can
add the DMM later if your needs
change.

20% over range on all ranges except 300 Vdc and
AC ranges and 1 A DC and AC current ranges.

For sinewave input >5% of range. For inputs from
1% to 5% of range and <50 kHz, add 0.1% of range
additional error.

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.

Input >100 mV. For 10 mV inputs, multiply %
of reading error x 10.

For total measurement accuracy,
add temperature probe error.
