PRECAUTIONS FOR USE
This instrument is designed to be powered by a mains voltage of category II. The main energy sources are 120 V eff or 240 V eff.
Use only the power cord supplied with the unit.
Carefully read the following safety precautions to avoid any personal injuries or damages to the instrument and any product
connected to it. To avoid potential hazards, please use the instrument as specified.
Failure to observe the safety instructions may result in electric shock, fire, explosion, or destruction of the instrument and of the
installations.
Observe all terminal ratings. To avoid fire or electric shock, please observe all ratings and sign instructions on the instrument.
Before connecting the instrument, please read the manual carefully to gain more information about the ratings.
The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken
in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument.
If you use this instrument other than as specified, the protection it provides may be compromised, thereby endangering you.
Do not use the instrument if it seems to be damaged, incomplete, or poorly 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 set aside for repair or scrapping.
Ground the Instrument. The instrument is grounded through the protective ground conductor of the power line. To avoid electric
shock, the ground conductor must be connected to the earth ground. Make sure the instrument is grounded correctly before
connecting its input or output terminals.
Do not alter or remove the grounding. Without grounding, all conductive elements (including control buttons) can cause
electrocution. Failure to follow these instructions may result in injury or death.
Before using your device, check that it is perfectly dry. If it is wet, it must be thoroughly dried before being connected or being
operated in any way.
Use personal protection equipment systematically.
When handling the leads, test probes, and crocodile clips, keep your fingers behind the physical guard.
Connect the signal wire correctly. The potential of the signal wire ground is equal to the earth, therefore do not connect the
signal wire to a high voltage. Do not touch the exposed contacts or components.
Use properly rated power line connections. Use only the specified power line which has been approved by your local regulatory
agency.
All troubleshooting and metrological checks must be performed by competent and accredited personnel.
When using the device, keep your fingers behind the physical guard.
Avoid circuit or wire exposure. Do not touch exposed contacts or components when the power is on.
The safety of any system in which this device is incorporated is the responsibility of the system integrator.
Unless otherwise specified, grounding on the front or rear panel of the unit is only indicative and is not without risk.
Do not use the device in an explosive or flammable atmosphere.
Comply with the environmental conditions of use:
- Do not operate in wet/damp conditions.
- Do not operate:
- in an explosive atmosphere.
- In a harmful or corrosive environment, in the presence of smoke, flammable gases or vapors and fine
particles
- If the temperature is different from the operating temperature specified in this manual.
- At a high altitude that would alter atmospheric pressure or if the ambient gas is not air.
- In environments where air circulation is difficult, even if temperatures are within specifications.
- In full sun.
Keep the surface of the instrument clean and dry.
This instrument is designed for use in a place with a degree of pollution 2. The operating temperature is between 0°C and 40°C,
Operating humidity must be 90% relative humidity at < 35°C and 60% relative humidity at 35°C – 40°C non-condensing.
The measurement may be distorted if carried out in a non-compliant environment. The measurement may be distorted if carried
out in an environment subject to rapid variations in temperature, humidity or brightness, mechanical vibration or shock, electrical
noise or disturbance, high magnetic or electrical field.
This instrument contains one or more fans. For the continued safe use of the appliance, it is essential that the air inlets and
exhaust ports are not obstructed by dust or debris that could reduce the airflow. Leave a gap of at least 25mm around each side of
the instrument that contains air inlets and air exhaust ports. If the instrument is installed in a test bay, position the power devices
above the instrument to reduce circuit heating. Do not use the instrument if you cannot verify the proper operation of the fan(s)
(note that some fans may have an intermittent operating cycle). Do not insert any objects into or out of the fan.
