1.4. FUNCTIONS
PAC 27 ammeter clamps are used to measure DC currents up to 1400A, AC currents up to 1000Arms
(1400A peak), and combined currents (AC+DC) without opening the circuit in which the currents flow.
They indicate the shape and amplitude of the current measured in the form of a voltage.
They are used with oscilloscopes.
They can be powered by a battery or at 5Vdc via the optional micro‑USB connector.
PAC clamps include:
„ a range overshoot indicator,
„ a power supply indicator,
„ a zero adjustment pushbutton,
„ automatic standby to prolong battery life,
„ one or two ranges depending on the model (sensitivity 1 and 10mV/A),
„ a micro‑USB connector to connect an external power supply.
„ Use a screwdriver to unscrew the captive screw
of the battery compartment cover.
„ Remove the battery compartment cover ➀.
Ž
„ Connect the battery to the snap-on connector;
take care with the polarity ➁.
„ Place the battery in its compartment ➂.
„ Put the battery compartment cover back in place;
make sure that it is completely and correctly
closed.
