Mechanical Data
The front panel of the Universal Power Meter is made of 5 mm
thick laminate, matt blue in colour with white engraving
representing the built-in function groups.
The rear of the Board is protected with a grey plastic cover. Its
shape allows the Board to be placed at an ergonomically favourable
angle for example on a table.
To conduct the experiments, the Universal Power Meter can be
placed on a table or suspended in an hps bench rack for demonstration
purposes.
Dimensions / weight
– 133 x 297 x 95 mm (w x h x d) / weight: approx. 0.9 kg
