IEC, EN and DIN Standards and VDE Regulations

for Electrical Measuring Instruments

Our panel meters and limit transducers (MESSCONTACTER) comply with the regulations

set forth in European guidelines 73/23/EWG and 89/336/EWG, which has been substan-

tiated by adherence to the following standards:

IEC 61010-1/A2/ EN61010-1/A2/ VDE 0411-1/A1 (safety requirements)

IEC 60051/EN 60051/DIN EN 60051 (measuring instruments with scale display)

EN 50081-2: 1993 EMC (interference emission, industrial)

EN 50082-2: 1995 EMC (interference immunity, industrial)

The most important regulations for the manufacture of electrical measuring instruments

included therein, as well as their characteristics, are defined below.

Accuracy

The accuracy of a measuring instrument or any of its accessories is determined by inher-

ent deviation limits and influence error limits.

Inherent deviation is the measurement deviation of a measuring instrument and/or any of

its accessories, when these are operated under reference conditions in accordance with

DIN EN 60051.

Measuring instrument influence error is the difference between two indicated values for

the same measured quantity, when the individual influence variable demonstrates two

different, predetermined values, one after the other, within nominal range of use in accor-

dance with DIN EN 60051.

Our measuring instruments comply with accuracy class 1.5 unless otherwise specified for

individual measuring instrument types.

The accuracy class is indicated on the scale, for example Class 1.5, which means that the

limits for inherent deviation are equal to ± 1.5% of the reference value.

The reference value is generally the upper measuring range limit with the following

exceptions:

• Reference value is equal to the sum of the absolute values which correspond to the

upper and lower measuring range values, as long as both the electrical and the

mechanical zero points lie within the scale.

• Reference value is equal to 90 electrical degrees for power factor meters.

Vibration and Shock Resistance

Our measuring instruments comply with requirements per DIN EN 60051-1

Scale and Pointer Design

The scales and pointers in our instruments comply with DIN 43802, parts 2 through 4.

Protection per DIN VDE 0470, Part 1 (EN 60529)

Housing front: IP 52

Temperature Limit Values

Operating temperature range per DIN EN 60051-1: −10 ... +55°C

Storage temperature range: −25 ... +65°C

Applications Range (climatic category)

Our measuring instruments comply with VDI/VDE 3540, page 2:

Safety Regulations
