A long pressing (>2s) of key
MODE/MXMNPK
allows for the activation/deactivation of
continuous detection of maximum value (MAX), minimum value (MIN), positive peak (Pk+),
negative peak (Pk-) of the quantity (voltage or current) to be measured. The values are
constantly updated and are displayed cyclically every time the same key is pressed. This
function is not active in position . Press and hold key
MODE/MXMNPK
(>2s) or use the
selector to exit the function.
4.2.4. Keys

allows for the following operations::
Setting of the full scale value of flexible clamp transducer (optional accessory - option
“ ”
) in position among values:
30A, 300A, 3000A
for AC current measurement.
Setting of the full scale value of standard clamp transducer (option
“ ”
) in position
among values:
1A, 10A, 30A, 40A, 100A, 200A, 300A, 400A, 1000A, 2000A, 3000A
for AC and DC current measurement.
