Accuracy Class

Alt the instruments are manufactured in 1.0 1.5 2.5 accuracy class (if no special indications).
The precision for reduced scale instuments (F2-F3-F5) will be<20%, with stop time <2 second.

Overloads

All amperometry circuits support an overloadof 1.2 in continuous and 10 in during 5 seconds.

Working Voltage: 650V

Test voltage: 2000V-50Hz/60Hz, for 1 minute

Insulation:

Insulation reference voltage 0.6KV.Working temperature20°C(±10°C)working range between -25°C ~ +55°C

Vibrations

±0.25mm amplitude at 50Hz/60Hz(CE68-2-6).

Humidity

Ambient relative humidity 85% without condensing, with 35°C tem-perature for max. 60 days per year.Yearly average humidity must benot higher than 65%(DIN 40040).

Tropical Version

95% relative humidity.for a maximum of 30 days per year.

Mounting Position

The normal execution of our instruments is for vertical mounting.theother mounting positions are known in advance, please indicate theangle of inclination when ordering.

Scales

The full scale deflections correspond to DIN 4371.
The scale divisions correspond to DIN 43802.
