)
As related to scale length
Scale lengths: R1 l = 46 mm
R2 l = 71 mm
R3 l = 80 mm
Ω l = 67 mm
Ul = 66 mm
2)
Within the marked area of the respective scale (nominal range of use)
Accuracy
Insulation resistance Class 1.5 in reference to scale length
after electrical zero balance
Direct and
alternating current class 2.5
Display
Movement Moving coil with core magnet
Turn-on performance
for insulation resistance measurement
An electronic voltage limiter prevents the voltage at the device
under test from substantially exceeding nominal voltage at turn-on
(see following characteristic curves).
