The digital multimeter has been designed for many years of re- liable use, provided that the following recommendations are observed for its maintenance and care:

1. THE METER MUST BE DRY. Wipe the dampened meter.
2. THE METER MUST BE USED AND STORED IN NORMAL TEMPERATURES. Extreme temperatures may shorten the life of electronic components and distort or melt plastic parts.
3. THE METER MUST BE HANDLED CAREFULLY AND GENTLY. Dropping the meter may damage its electronic elements or the housing.
4. THE METER MUST BE KEPT CLEAN. From time to time wipe the housing with a damp cloth. DO NOT use chemicals, solvents or detergents.
5. USE ONLY NEW BATTERIES OF RECOMMENDED SIZE AND TYPE. Remove the old or discharged batteries from the meter to avoid leakage and damage.
6. IF THE METER IS TO BE STORED FOR LONGER THAN 60 DAYS, remove the batteries and keep them separately.

**** The electronic system of the meter does not require maintenance.

Storage

During the storage of the device, the following recommendations must be observed:

• make sure that the meter and accessories are dry,
• when the device is to be stored for longer time, remove the batteries.

Dismantling and disposal

Worn-out electric and electronic equipment should be gathered selectively, i.e. it must not be placed with the waste of another kind. Worn-out electronic equipment should be sent to a collection point in accordance with the law of waste electrical and electronic equipment. Before the equipment is sent to a collection point, do not dismantle any elements.
Observe local regulations concerning the disposal of packages, waste batteries, and accumulators.

SONEL Testing and Calibration Laboratory has been accredited by the Polish Center for Accreditation (PCA) – certificate no. AP 173.

Laboratory offers calibration for the following instruments that are used for measuring electrical and non-electrical parameters.

• METERS FOR MEASUREMENTS OF ELECTRICAL
  PARAMETERS
  o voltage meters,
  o current meters (including clamp meters),
  o resistance meters,
  o insulation resistance meters,
  o earth resistance and resistivity meters,
  o RCD meters,
  o short-circuit loop impedance meters,
  o power quality analyzers,
  o portable appliance testers (PAT),
  o power meters,
  o multimeters,
  o multifunction meters covering the functions of the abovementioned instruments,

• ELECTRICAL STANDARDS
  o calibrators,
  o resistance standards,

• METERS FOR MEASUREMENTS OF NON-ELECTRICAL
  PARAMETERS
  o pyrometers,
  o thermal imagers,
  o luxmeters.

The Calibration Certificate is a document that presents a relation between the calibration standard of known accuracy and meter indications with associated measurement uncertainties. The calibration standards are normally traceable to the national standard held by the National Metrological Institute.
According to ILAC-G24 „Guidelines for determination of calibration intervals of measuring instruments”, SONEL S.A. recommends periodical metrological inspection of the instruments it manufactures no less frequently than once every 12 months. For new instruments provided with the Calibration Certificate or Validation Certificate at the factory, re-calibration should be performed within 12 months from the date of purchase, however, no later than 24 months from the date of purchase.

ATTENTION!
The person performing the measurements should be absolutely sure about the efficiency of the device being used. Measurements made with an inefficient meter can contribute to an incorrect assessment of the effectiveness of health protection and even human life.
