Cleaning The Calibrator; Self-Resetting Fuses - Fluke 724 Calibration Manual

Cleaning the Calibrator

To avoid electric shock or damage to the Calibrator, never allow water
inside the Calibrator's case.
If the Calibrator requires cleaning, wipe it down with a cloth that is lightly dampened
with water or a mild detergent.
Do not use aromatic hydrocarbons, chlorinated solvents, or methanol-based fluids when
cleaning the Calibrator. To avoid damaging the case, never apply solvents to the
Calibrator.

Self-Resetting Fuses

The Calibrator has self-resetting fuses that protect each input from overloads. The fuses
open when heated by a current overload, and close when they cool down. When an
input's fuse is open, the input's functions will not work.
The time required for a fuse to reset depends on the magnitude of the overload. If a fuse
does not reset, return the Calibrator to an authorized service center for repair.
