Safety Precautions And Procedures; Preliminary Instructions - HT HT304N Manual De Instrucciones

1. SAFETY PRECAUTIONS AND PROCEDURES

This instrument complies with safety Standards EN61010-1 related to electronic measuring instruments
For your own safety and to avoid damaging the instrument follow the procedures described in
this instruction manual and read carefully all notes preceded by this symbol
When taking measurements:
 Do not take measurements in presence of explosive or highly flammable gas and combustibles or in
dusty places.
 Keep you insulated from and do not touch the object under test, any exposed metal part such as test
lead ends, sockets, fixing objects, circuits etc.
 Avoid doing that if you notice anomalous conditions such as breakages, deformations, fractures, etc.
 Pay utmost attention when taking measurements of voltage higher than 25V in special places (building
yards, etc.) and higher than 50V in ordinary places due to the risk of electric shock.
The following symbols are used in this manual as well as on the instrument:
CAUTION: please read carefully this manual in order to understand the nature of the
potential danger and the actions to undertake.
Refer to the instruction manual. An improper use may damage the instrument or its components
as well as endanger the user.
The barred symbol of the rubbish bin shown on the equipment indicates that, at the end of its
useful life, both the products and its accessories shall be collected separately from other waste
and correctly disposed.

PRELIMINARY INSTRUCTIONS

 HT304N is a passive sensor and do not require any power supply.
 Avoid exposing the instrument to mechanical shock paying additional attention to the glass.
 Protect the glass against any contact with abrasive surfaces.
 Do not apply any voltage to instrument's outputs.
 Avoid any mechanical shocks to the instrument's outputs and connection cable.
 Before the usage clean the glass using a wet cloth. Do not use acetone, alcohol, solvents, etc..
 Install the sensor in position clear of obstructions that may introduce shading or reflections effects by
distorting the sensor reading.
 Do not install the sensor close to white coloured walls or other objects that could reflect the sun's rays on it.
 Connect the cable to the desired cell (MONO or MULTI) before the placement of the sensor.
In order to use the sensor for irradiance measurement into Photovoltaic installations:
o Always check the parallelism between the sensor and the photovoltaic module under
consideration (error max
PV module surface could affect the outcome of the measure.
o Verify that the stirrup has the same north-south direction of the module / modules to be
examined. (error max
sensor and the modules could affected heavily the result of the measure.
o The usage of the stirrup is highly recommended. Fix the stirrup in a central position of
the PV module edge. The stirrup is provide of a fixing screw compatible with holes
placed on the back side of the PV module frame.
o Once positioned the stirrup, insert the sensor into its holder.
o Expose the sensor to the test conditions (radiation temperature, inclination) at least 1
minute before performing the readings in order to avoid working with the sensor not yet
in steady state.
