Overvoltage Installation Category - RS Pro RS-9963T Manual De Instrucciones

Digital Multimeter/ English
1. Introduction.
This meter measures AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency
(electrical & electronic), Diode Test and Continuity plus Thermocouple Temperature. Proper
use and care of this meter will provide many years of reliable service.
2. Safety
This symbol adjacent to another symbol, terminal or operating device
indicates that the operator must refer to an explanation in the
Operating Instructions to avoid personal injury or damage to the meter.
This WARNING symbol indicates a potentially hazardous situation,
WARNING
which if not avoided, could result in death or serious injury.
This CAUTION symbol indicates a potentially hazardous situation,
CAUTION
which if not avoided, may result in damage to the product.
This symbol advises the user that the terminal(s) marked must not be
connected to a circuit point at which the voltage with respect to earth
ground exceeds (in this case) 1000 VAC or VDC.
This symbol adjacent to one or more terminals identifies them as
being associated with ranges that may, in normal use, be subjected to
particularly hazardous voltages. For maximum safety, the meter and its
test leads should not be handled when these terminals are energized.
This symbol indicates that a device is protected throughout by double
insulation or reinforced insulation.
