maximum inward values.
Be careful when measuring above 60V DC or
•
30V AC. These voltages may cause electric
shock.
When using a measuring sensor, make sure
•
that your fingers do not touch the metal
parts of the sensor and are behind the finger
protection area at all times.
Before switching between measuring
