NOTE:
In DC current measurement mode, this key is the “ZERO”key�
However, in other functions, this key is the “REL” key�
“REL” Function: Relative (REL) mode: Stores existing reading (a
delta) and resets display to zero� Sets a relative reference point
tomeasure against the next reading�
“ZERO” Function: This function allows the user to set the
magnetization effects to zero when measuring DC� It must be
performed after each high amplitude current measurement� With no
conductor inserted into the clamp, press and hold this key (approx�
3 seconds) until a beep sounds and the “ZERO” symbol appears on
the display�
HOLD:
Captures and holds a stable measurement�
Make sure that the function is deactivated at the start of the test�
Otherwise an incorrect measurement result will be simulated!
Work Light: Press and hold this button for more than 2 seconds to
switch the work light on or o.
