The Hook, Power Probe’s latest circuit tester, can now connect to systems from 12V to 48V. Power Probe’s new “Smart Tip Advantage” senses the probe tip condition and selects the correct meter. The Hook also displays it’s current draw in amps. The AC voltage threshold sets the Power Probe Hook to automatically turn on and display amplitude and frequency when an AC signal is detected on the tip. Other features include: min/max voltage, current, and resistance measurements, along with peak-peak voltage, frequency counter, positive and negative pulse width and duty cycle and an isolated continuity tester.
