a case.
c) Measuring procedure
The measuring range of the product is of max. 3000 A. When measuring more than 3000 A, the display will
show “OL”.
• Switch on the product by pressing and holding the /Hold button (2) for 2 seconds.
• The product immediately starts measuring the alternating current of the electric conductor embraced by the
exiblecurrentsensor(5);thereadingappearsinthedisplay(1).
• Brieypressthe /Hold button to freeze the displayed value. “HOLD” appears in the left corner of the display.
• Brieypressthe /Hold button again in order for the display (1) to show the current value again; “HOLD” will
