Measurement Categories, refer to
figure 1 (page 2)
CAT I: For measurements performed on circuits not
directly connected to a mains supply.
CAT II: For measurements performed on circuits not
directly connected to the low-voltage insta l-
lation.
CAT III: For measurements performed in the building
installation.
CAT IV: For measurements performed at the sou rce
of the low-voltage installation.
Read First: Safety Information
To avoid possible electric shock or personal in-
jury, follow these guidelines:
Read „Safety Information“ before use
Adhere to local and national safety codes. Indi-
vidual protective equipment must be used to
prevent shock and injury.
Use caution when working with voltages above
30 V ac rms, 42 V ac peak, or 60 V dc. These
voltages pose a shock hazard.
Check the test leads f
or continuity.
Replace
damaged test leads before use.
Ensure that test leads and probes are fully
mated to each other and the equipment.

Appropriate Usage
The accessories may only be used under those
conditions and for those purposes for which it
was conceived. For this reason, safety refer-
ences, technical data (including environmental
conditions), and the usage in dry environments
must be followed.
If probes are modified by the user, operational
safety is no longer ensured.
Accessories-handle surface, refer to
figure 2 (page 2)
Only touch test leads and test probes at handle
surface provided. Never directly touch test probe
tips or touch test probes beyond the barrier.
Fuse Replacement
The fuse can be checked with a simple continuity
test.
Prior to fuse replacement, disconnect the acces-
sory (cable or probe) on both side every time.
Exclusively use fuses of voltage and current
values in compliance with the technical data
section. Using auxiliary fuses, in particular short-
circuiting fuse holders is prohibited and can
cause probe destruction or ser
ious
bodily injury
of operator.
Completely unsrew the fuse holder (FH). See figure 3
(page 2)
Remove defect fuse.
Push the fuse into the fuse holder.
Screw in fully the fuse holder to the end stop.

Cleaning
If the probes are dirty after use, cleam them by using
a damp cloth and a mild household detergent.
Prior to cleaning, ensure that probes are discon-
nected from external voltage supply and any
other instruments connected (such as UUT, con-
trol instruments, etc.).
