6. For standard clamp transducers, press key MODE/MXMNPK to select “AC”, “DC” or
“AC+DC” measurement. Anyway, the instrument automatically recognizes AC or DC
quantities.
7. Insert the red cable into input terminal V  /+ and the black cable into input terminal
COM/.. For standard transducers with Hypertac connector, use optional adapter
NOCANBA. For information on the use of clap transducers, please refer to the relevant
user manual.
8. Insert the cable into the center of the jaws (see Fig. 36). The value of current is shown
in Fig. 37

9. Press key MODE/MXMNPK to display the value of frequency of AC current with a high
resolution (see Fig. 38).

11. Message
“>300A” indicates that the value of current measured is higher than the set
full scale (300A in case of Fig. 39). If the display shows the messages
“<32.00Hz” or
“>1000Hz”, the measured value of current frequency is out of the measuring range
32Hz ÷ 1000Hz.
12. To use functions HOLD, MAX/MIN/PK, H/H%/H, see § 4.2
