Cleaning
To clean the exterior of the probe, use a soft cloth moistened with either distilled
water or isopropyl alcohol. Before using the probe again, make sure to dry it com-
pletely.
Instrument damage caused by cleaning agents
Cleaning agents contain substances that may damage the instrument; for
example, solvent may damage the labeling or plastic parts.
Never use cleaning agents such as solvents (thinners, acetone, etc.), acids,
bases or other substances
Instrument damage caused by static electricity
Before cleaning the facing surfaces of the sensor head, discharge any static
electricity at your hands. Thus you ensure that a high voltage caused by
static electricity will not be applied to the device. Application of a high volt-
age to the device may damage the internal Hall elements or circuitry. Static
electricity at your hands may have built up by touching a nearby metal
object.
