1.1.

PRELIMINARY

 This instrument has been designed for use in environments with pollution degree 2.
 It can be used for DC and AC VOLTAGE measurements on installations of CAT IV
600V or CAT III 1000V
 When using the instrument always respect the usual safety regulations aimed at
protecting you against dangerous electric currents as well as the instrument against
incorrect operation
 Do not test nor connect to any circuit exceeding the specified overload protection
 Do not take measurements under environmental conditions exceeding the limits
indicated in § 6.2.1.
 Check the state of the internal batteries before use and replace them if necessary
 Prior to usage ensure perfect instrument function (e.g. on a known voltage source)
 The functionality of the instrument must be quickly checked before and after use by
using the test probes. If the indication of one or more steps fails or if no functionality is
verified, the instrument is no longer to be used
 The different signals indicated by the instrument (including the ELV limit indication)
must not be used for measuring purposes
 Before using the instrument with audible indicator at locations with a high background
noise level please evaluate if the audible signal is perceptible
 Position the instrument in order to avoid hiding of visual indication or covering of sound
transmitter
 Check the state of the voltage source before to use the instrument
1.2.

DURING USE

Read the recommendations which follow and the instructions in this manual:
 Improper use may damage the instrument and/or its components or injure
the operator
 The instrument is designed to be used by skilled persons and according
with safe methods of work
 The voltages marked on the instrument are nominal values or nominal
range values. The instrument is to be used only on installations with the
specified nominal voltages or nominal voltage ranges
 When the instrument is connected to circuits never touch an unused terminal.
 When measuring resistors do not add any voltage. Although there is a protection
circuit, excessive voltage would still cause malfunction.
