This Digital Multimeter gives True 7½- (or 8½-) Digit resolution.
The resolution specifications are based on a 28-bit A/D converter that provides the resolution
needed to discern smaller changes. This higher resolution also provides greater dynamic range,
making it possible to measure from 1µV to 20V on a single range, thus avoiding range shift errors and delays.
This Model maintains full rated accuracy at reading rates up to 44/second on DCV and ohms.
This model uses a unique single-phase method for 4-wire ohms measurements. This makes it twice as fast
for a given power line cycle rate. This also eliminates errors due to changing lead resistances that can
result from fast test handlers. A built-in "open-lead" detection circuit also eliminates many production
test problems. A patented circuit design makes the 2001 and 2002's AC measurements several times more
accurate than competitive DMMs, thus maintaining very good accuracy (better than 0.1%) down to 1Hz.
The wide bandwidth of these DMMs allows for accurate measurements of high frequency AC signals without
the need for a special AC meter.
