SIMPLE LOGGER II
Before using the device, read manual and be sure that you understand it fully; observe the safety
instructions.
Failure to observe the safety instructions may result in an electric shock, fire, explosion, destruction of the
device, or destruction of the installations.
These safety instructions ensure the safety of individuals and proper operation of the device.
These devices comply with safety standard EN 61010-1 or EN 61010-2-032 for the indicated voltages and
installation categories, indoors, at an altitude of less than 2000m, with a degree of pollution not exceeding 2.
♦ Do not use the device in an explosive atmosphere or in the presence of flammable gases or fumes.
♦ Do not use the device on networks of which the voltage or category is higher than those mentioned.
♦ Do not exceed the rated maximum voltages and currents between terminals and with respect to earth.
♦ Do not use the device if it appears to be damaged, incomplete, or incorrectly closed.
♦ Before each use, check the condition of the insulation on the leads, housing, and accessories. Any
item of which the insulation is deteriorated (even partially) must be removed and repaired or
scrapped.
♦ Use leads and accessories of which the rated voltages and categories are at least equal to those of
the device.
♦ Observe the environmental conditions of use.
♦ Strictly observe the characteristics of the fuse.
♦ Do not modify the device and do not replace components with "equivalents". Repairs and adjustments
must be done by approved skilled personnel.
♦ Replace the batteries as soon as the "Low Bat" symbol appears.
device or remove the clamp-on ammeter from all cables before opening the battery compartment
cover.
♦
Use personal protective equipment when conditions require.
♦
Keep your hands away from unused terminals of the device.
♦
When handling probes, probe tips, clamp-on ammeters, and alligator clips, keep your fingers
behind the guards.
♦ For measurements of dangerous voltages, connect the black lead first, to the black terminal of the
device, then to the low point of the source to be measured (the point closest to earth potential). Then
connect the red lead to the red terminal of the device, then to the hot point of the source to be
measured. Disconnection must be done in reverse order: disconnect the red lead first, then the black
lead.
WARNING The device L642 uses wired probes to measure very small voltages. Because of this, exposing
the product to strong electromagnetic radiation may perturb its operation and lead to the recording of
erroneous values.
