Cleaning the Calibrator
XWWarning
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.
Replacing the Batteries
XWWarning
To avoid electric shock, remove the test leads from the Calibrator
before opening the battery door. Close and latch the battery door
before using the Calibrator.
To avoid false readings, which can lead to possible electric shock or
personal injury, replace the batteries as soon as the low battery
indicator (
B) appears.
When replacing the batteries, always use four new AA batteries. Never
mix new and used batteries in the Calibrator.
