B) Relative Measurement; C) Current Measurement 'A - VOLTCRAFT 2274366 Operating Instructions Manual

b) Relative measurement

You can measure values absolutely (normal measuring mode) or measure a value in relation to
the previous measurement.
• To accept a currently recorded measured value as the output value (zero value), press
the REL ZERO button (8) during a measurement in normal measuring mode. The display
changes to '000'. 'REL' and
To switch back to normal measuring mode, press the REL ZERO button (8) again. If you set
•
the rotary switch (3) to a different measuring function, the measuring device also returns to
normal measuring mode.
• You can use the HOLD function in the same way for relative measurements. An active HOLD
function is switched off when you switch from relative measurement to normal mode.

c) Current measurement 'A'

The current is measured wirelessly via the current clamp (1). The sensors in the current clamp
detect the magnetic field created by current-carrying conductors.
Ensure that the conductor always passes through the current clamp correctly (observe
the line markings).
Do not use the current clamp to surround more than one conductor.
