General Maintenance
Dirt or moisture in the terminals can distort readings. Cleaning procedures are as
follows:
1
Turn the clamp meter off and remove the test leads.
2
Turn the clamp meter over and shake out any dirt that may have accumulated
in the terminals.
3
Wipe the case with a damp cloth and mild detergent — do not use abrasives or
solvents.
WARNING
Ensure that terminal connections are correct for a particular measurement
before making the measurement. To avoid damaging the device, do not
exceed the rated input limit.
NOTE
Prevent rust by wiping metal surfaces with oil from time to time. If rusted, lightly
sand the affected area with very fine sandpaper and then oil the metal surfaces.
