Before any operation, make sure that connecting leads used and electronic
load are in good condition.
Measurement in dangerous proximity of electrical installations can be made
only when instructed by a responsible electrical specialist. And never work
alone.
Keep the instrument dry.
To avoid interference, do not use the instrument where there is intense
environmental electromagnetic field; otherwise the detection or measurment
result may be wrong.
The instrument may only be used on systems complying with the nominal
voltages indicated in the technical data section in this manual.
It is recommended to exclusively connect the transmitter from the phase
toward the neutral conductor. If transmitter connection is realized from the
phase toward the protective conductor, the functional safety of the protective
conductor must be tested first, in compliance with DIN VDE 0100. The reason
is that when connecting the transmitter from phase toward ground, all parts
being connected to the earth may be live in the event of an error ( if the earth
resistance does not comply with the prescriptions ).
If the RCD trips when connecting the transmitter ( with reference to the
protective earth contact PE ), a fault current is already active within the
installation which generates the RCD tripping when cumulated to the
additionally fed current.
The instrument can only be used under those conditions and for those
purposes for which it was designed.
Because the instrument's voltage amplitude/value indication is affected by
many factors ( such as environmental electromagnetic field, the distance
between the receiver and the conductor under test, the resistance of the
connecting leads, the connection resistance, etc ), do not teat or regard any
voltage amplitude/value indicated by the instrument as the actual voltage
amplitude/value of the circuit under test.
Do not tamper with the internal circuits of the instrument.
Never short the positive and negative terminals of any battery. Do not place
any battery in fire. Do not dismantle or bump any battery.
