Displayed current represents r.m.s. value for current clamp with ratio 1000:1.
Use test clamp supplied by METREL or other with similar characteristics (current
output, ratio 1000:1, appropriate measurement range; consider error of test clamp
when evaluating measured results)!
Current clamps Metrel A 1074 and A 1019 are suitable for use with the instrument
in range of 0.2 A  20 A. Below 0.2 A they can be used as indicator only. They are
not suitable for leakage current measurements.
The only Metrel current clamp, suitable for leakage current measurements, is
A 1018 (1000 A/1 A).
