the equipment:
- Mains plug: Shall be national approval;
- Mains connector: C13 type;
- Cable:
1) Length of power supply cord: less than 3 m;
2) Cross-section of conductors: at least 0.75
mm2;
- Cord type: Shall meet the requirements of IEC
60227 or IEC 60245 (e.g.: H05VV-F, H05RN-F)
or national approval.
Un jeu de cordons d'alimentation approprié
doit être utilisé avec l'équipement:
- Prise secteur : Doit être approuvée au niveau
national ;
- Connecteur secteur : type C13 ;
- Câble:
1) Longueur du cordon d'alimentation : moins
de 3 m;
2) Section des conducteurs : au moins 0,75
mm2;
- Type de cordon : doit répondre aux exigences
de la norme CEI 60227 ou CEI 60245 (par
exemple : H05VV-F, H05RN-F) ou à
l'approbation nationale.
(Measurement categories) EN 61010-1specifies the measurement
categories and their requirements as follow.
Measurement category IV is for measurement performed at the
source of low-voltage installation.
Measurement category III is for measurement performed in the
building installation.
Measurement category II is for measurement performed on the
circuits directly connected to the low voltage installation.
0 is for measurements performed on circuits not directly
connected to Mains.
Do NOT position the equipment so that it is difficult to
disconnect the appliance inlet or the power plug.

To avoid electrical shock connect the protective
grounding conductor of the AC power cord to
an earth ground.
Pour éviter tout choc électrique, connectez le
conducteur de mise à la terre de protection du
cordon d'alimentation secteur à une prise de
terre.
To avoid electric shock, the power cord
protective grounding conductor must be
connected to ground. No operator serviceable
components inside. Do not remove covers.
Refer servicing to qualified personnel.
Pour éviter les chocs électriques, le conducteur
de mise à la terre du cordon d'alimentation doit
être connecté à la terre. Aucun composant
réparable par l'opérateur à l'intérieur. Ne

Cleaning
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material
such as benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
Temperature: 0°C to 40°C
Humidity: 0 to 85% RH
Altitude: <2000m
Overvoltage category II
(Pollution Degree) EN 61010-1specifies the pollution degrees and
their requirements as follow. The instrument falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.
Storage
environment
Location: Indoor
Temperature: -20°C to 70°C
Humidity: <90% RH
Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.
