Thank you for purchasing a Model 205 Clamp-on Meter.
For best results from your instrument and for your safety, read the enclosed
operating instructions carefully and comply with the precautions for use. These
products must be only used by qualified and trained users.
Meanings of the symbols used on the device
CAUTION - Risk of Danger! Indicates a WARNING and that the operator
must refer to the user manual for instructions before operating the
instrument in all cases where this symbol is marked.
Risk of electric shock. The voltage at the parts marked with this symbol may
be dangerous.
Refers to a type A current sensor. This symbol signifies that application
around and removal from HAZARDOUS LIVE conductors is permitted.
9V battery
The CE marking indicates compliance with European directives
Double insulation or reinforced insulation
In the European Union, this product is subject to a separate collection
system for recycling electrical and electronic components In accordance
with directive WEEE 2002/96/EC
AC – Alternating current
AC and DC – Alternating and direct current
Ground/Earth
PRECAUTIONS FOR USE
This device complies with safety standards IEC-61010-1 and 61010-2-032 for voltages of
1000V in category III or 600V CAT IV at an altitude of less than 2000m, indoors, with a
degree of pollution not exceeding 2.
These safety instructions are intended to ensure the safety of persons and proper operation
of the device.
The operator and/or the responsible authority must carefully read and clearly
understand the various precautions to be taken in use.
If this instrument is used other than as specified, the protection it provides may be
compromised, thereby endangering you.
Do not use the instrument in an explosive atmosphere or in the presence of flammable
gases or fumes.
Do not use the instrument on networks of which the voltage or category exceeds those
mentioned.
Do not exceed the rated maximum voltages and currents between terminals or with
respect to earth.
Do not use the instrument if it appears to be damaged, incomplete, or not properly
closed.
Before each use, check the condition of the insulation on the leads, housing, and
accessories. Any element of which the insulation is deteriorated (even partially) must
be set aside for repair or scrapped.
Use leads and accessories rated for voltages and categories at least equal to those of
the instrument. If not, an accessory of a lower category lowers the category of the
combined Clamp + accessory to that of the accessory.
Observe the environmental conditions of use.
Do not modify the instrument and only use factory replacement parts. Repairs and
adjustments must be done by approved qualified personnel.
Replace the batteries as soon as the symbol appears on the display of the unit.
Disconnect all leads before opening the battery compartment cover.
Use personal protective equipment when conditions require.
Keep your hands away from the unused terminals of the instrument.
When handling the test probes, alligator clips, and clamp ammeters, keep your fingers
behind the physical guard.
As a safety measure, and to avoid repeated overloads on the inputs of the device,
configuration operations should only be performed when the device is disconnected
from all dangerous voltages.
MEASUREMENT CATEGORIES
Definitions of the measurement categories:
CAT II: Circuits directly connected to the low-voltage installation.
Example: power supply to household electrical appliances and portable tools.
CAT III: Power supply circuits in the installation of the building.
Example: distribution panel, circuit-breakers, fixed industrial machines or
devices.
CAT IV: Circuits supplying the low-voltage installation of the building.

RECEIVING YOUR SHIPMENT
Upon receiving your shipment, make sure that the contents are consistent with the
packing list. Notify your distributor of any missing items. If the equipment appears
to be damaged, file a claim immediately with the carrier and notify your distributor
at once, giving a detailed description of any damage. Save the damaged packing
container to substantiate your claim.

2 THE BUTTONS
The buttons respond differently to short, long, and sustained presses.
The , and keys provide additional functions as well as the
detection and acquisition of parameters complementary to the basic
measurements.
Each of these buttons can be used independently of the others or in
conjunction with each other. This makes navigation simple and intuitive
when reviewing measurement results.
It is possible, for example, to either look up in sequence the MAX, MIN,
etc. values of the RMS voltage alone, or look up in sequence all of the
MAX (or MIN, or PEAK) values of all power measurements (W, VA, var,
etc.).
In this section, the icon represents the possible positions of the switch for the
button’s functionality.
2.1

This button is used to:
Store and look up the last values acquired specific to each function (V, A,

second functions marked in yellow next to the relevant positions of the switch.
It can also be used to modify the default values in the configuration mode
(see § 3.4).

2.4 BUTTON
2.4.1 Normal Mode
This button activates the detection of the MAX, MIN, PEAK+ and PEAK- values of
the measurements made.
Max and Min are the extreme mean values in DC and the extreme RMS values in
AC. Peak+ is the maximum instantaneous peak and Peak- is the minimum
instantaneous peak.

present measurement without exiting from
the mode (the values already detected are
not erased)
NOTE: The MAX, MIN, PEAK+ or PEAK-
symbols are all displayed, but only the
symbol of the measurement selected
blinks.
Example: If MIN has been selected, MIN
blinks and MAX, PEAK+, PEAK- are lit
steadily.

- Returns to the display of the present
measurement without exiting from the
mode (the values already detected are

- Exits the MAX/MIN/PEAK mode. The
values previously recorded are then
erased.
NOTE: If the HOLD function is enabled, it
is not possible to exit from the
MAX/MIN/PEAK mode. The HOLD
function must first be disabled first.
NOTE : ΔREL function can be used with the functions of the MAX/MIN/PEAK mode.
