1.4. FUNCTIONS
PAC 17 ammeter clamps are used to measure DC currents up to 600A, AC currents up to 400Arms (600A
peak), and combined 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.
