Measure DC Current
The Product measures current with the INPUT A and INPUT LO terminals. The
current should flow from the source's high terminal into the multimeter A terminal
and back to the source's low terminal out of the multimeter LO terminal.
Similar connection considerations are required for dc current measurement as for
dc voltage measurement. Use shielded twisted-pair cable to reduce induced
interference signals, and connect GUARD to the source of common-mode
voltage to provide a separate common-mode current path.
To prevent possible electrical shock, fire, or personal injury,

The current path between the Product terminals is not made when
the current functions are not in use or when front or rear terminals
are deselected.
The rear input terminals may be used to measure currents up to 2 A
only. The rear input A terminal does not share the front panel
automatic protection circuitry, and is instead protected by a fuse
mounted on the rear panel.
Maximum input current capability and protection: The front input
terminals may be used to measure currents up to 30.2 A with
protection for all ranges up to 30.2 A. The front input A terminal
protection for current ranges 1 A and lower has an overload
protection feature if the input significantly exceeds full range. This
protection is automatic and self-resetting, and does not interrupt
current flow. It remains engaged for 1 second after the overload is
removed to minimize circuit interaction and relay reactivation.
Damage will occur if >30.2 A is applied to the front current
terminals and the current source maximum compliance is >5 V.

HIGH CURRENT FLOW
Do not exceed the Measurement Category (CAT) rating of
the lowest rated individual component of a Product, probe,
or accessory.
Only use probes, test leads, and accessories that have the
same measurement category, voltage, and amperage ratings
as the Product. High current can cause excessive heating of
underrated conductors and may cause a fire.
