IMPORTANT: these instructions are for your safety. Read
them carefully before use and keep them for future use.
Warning:
1. Be particularly careful when using voltages above 25V AC (RMS) or 60V DC to
avoid damage or electric shock.
2. Never apply an input voltage higher than the maximum value of the range allowed
by the device manufacturer. This monitor is designed for low voltage applications.
(600V MAX IN AC/DC)
3. Never use the tester to measure the line feeding a device that generates a sudden
surge in voltage as it may exceed the maximum permitted voltage (e. g. motors).
4. Never use the tester if the test plungers or leads are damaged or broken. Make
sure they are never wet or damp; check that the tester and the leads are working
properly before commissioning.
5. Opening the housing gives access to hazardous voltage conductive parts. Any
action on internal circuits could result in hazardous use. Never use the disassem
bled tester. Before using it: check that the housing is properly closed and screwed in.
6. Always make sure your fingers are behind the test plunger guard during measure
ments. During the measurement, be careful not to come into direct or indirect
contact (e. g. with fingers) with high voltage conductive parts.
7. Be sure to disconnect the plungers of the leads from any voltage source and the
circuit to be measured; remove the plungers when changing function. Before per
forming any work (e. g. changing batteries) or before turning the rotary switch to
change functions, disconnect the tester.
8. Before taking a measurement, make sure the function selector switch is in the
correct position.
