Safety
This generator is a Safety Class I instrument according to IEC classification and has been designed to
meet the requirements of EN61010−1 (Safety Requirements for Electrical Equipment for Measurement,
Control and Laboratory Use). It is an Installation Category II instrument intended for operation from a
normal single phase supply.
This instrument has been tested in accordance with EN61010−1 and has been supplied in a safe condition.
This instruction manual contains some information and warnings which have to be followed by the user to
ensure safe operation and to retain the instrument in a safe condition.
This instrument has been designed for indoor use in a Pollution Degree 2 environment in the temperature
range 5°C to 40°C, 20% − 80% RH (non−condensing). It may occasionally be subjected to temperatures
between +5° and −10°C without degradation of its safety. Do not operate while condensation is present.
Use of this instrument in a manner not specified by these instructions may impair the safety protection
provided. Do not operate the instrument outside its rated supply voltages or environmental range.
Any interruption of the mains earth conductor inside or outside the instrument will make the instrument
dangerous. Intentional interruption is prohibited. The protective action must not be negated by the use of
an extension cord without a protective conductor.
When the instrument is connected to its supply, terminals may be live and opening the covers or removal of
parts (except those to which access can be gained by hand) is likely to expose live parts. The apparatus
shall be disconnected from all voltage sources before it is opened for any adjustment, replacement,
maintenance or repair.
Any adjustment, maintenance and repair of the opened instrument under voltage shall be avoided as far as
possible and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard involved.
If the instrument is clearly defective, has been subject to mechanical damage, excessive moisture or
chemical corrosion the safety protection may be impaired and the apparatus should be withdrawn from use
and returned for checking and repair.
Make sure that only fuses with the required rated current and of the specified type are used for
replacement. The use of makeshift fuses and the short−circuiting of fuse holders is prohibited.
This instrument uses a Lithium button cell for non−volatile memory battery back−up; typical life is 5 years.
In the event of replacement becoming necessary, replace only with a cell of the correct type, i.e. 3V
Li/Mn0
20mm button cell type 2032. Exhausted cells must be disposed of carefully in accordance with
2
local regulations; do not cut open, incinerate, expose to temperatures above 60°C or attempt to recharge.
Do not wet the instrument when cleaning it and in particular use only a soft dry cloth to clean the LCD
window. The following symbols are used on the instrument and in this manual:
