CIRCUTOR CVM-B Series - Manual (Page 33)

 frequency 60 Hz
L = 55 H = 65
Min = L * 0.95 Max = H * 1.05
P L = L + (( H - L) * 0.25) P H = H - (( H - L) * 0.25)
 Voltage THD
L = 0 H = 5
Min =0 Max = H * 2
P L = L + (( H - L) * 0.25) P H = H - (( H - L) * 0.25)
The alarm and pre-alarm zones L are not displayed.
 Current THD
L = 0 H = 20
Min =0 Max = H * 2
P L = L + (( H - L) * 0.25) P H = H - (( H - L) * 0.25)
The alarm and pre-alarm zones L are not displayed.
 Cosine phi and Power factor
L = -0.9 H = 0.9
Min = -Max Max = minor(L or H) * 1.2
P L = L + (( L - H+2) * 0.25) P H = H + (( L - H+2) * 0.25)
