Tip: BA27, BA39, BE27 and BE39
Maximum ammeters - BA and BE series are destined to measure the averaging RMS value of a a.c. current, in a 8 or 15 minutes' period.
An additional red pointer, displaced by the black pointer, shows the maximal current value which occurred from the last zeroing of the meter indication.
The applied bimetal movement is especially useful when measuring the load in power line, of generators, electrical motors and others, where important momentary changes of load occur.
- with bimetallic movement - BA series,
- with bimetallic and moving-iron movement - BE series,
direct measuring range for BA series: I = 0...6A,
direct measuring range for BE series: I = 0...1/2A, 0...5/10A,
measuring range with current transformer: I = 1 A or 5 A,
accuracy class: bimetallic movement: 3,
accuracy class - moving-iron movement: 1.5,
