(a) Arc Detect
On 12 volt systems, the incidence of arcing is low therefore, for ease of operation the Arc Detect has been disabled in all
modes. Arc detect is functional in Power Probe mode only when the source voltage exceeds 16V. Arc detect can interfere
with the function of some devices. When using the HOOK on vehicles with 24V and above source voltage, it may be neces-
sary to use Power Plus mode if the device you are powering are electrically very noisy as on some motors or horns. Use
caution and follow instructions on how to properly power up a circuit. Because of the danger present with higher voltages
to the vehicle and you, it is recommended to use Power Probe mode for powering up in these higher voltage systems when
VI
- POWER PLUS MODE
ARC DETECT IS DISABLED! Use CAUTION
This is an active mode used for activating electrical components similar to Power Probe Hook Mode except the Arc Detect
feature is disabled. The Power Switch and Circuit Breaker Preferences apply here in Power Plus Mode as they do in
Power Probe Hook Mode. Power Plus Mode will measure and display the Min/Max Current draw so you capture in rush
and stabilized current. High current can be an indication of a sticking or dragging motor or pump.
To access Power Plus Mode from Power Probe Hook Mode:
1. Press SEL once.
2. Press U once
3. Press SEL.
4. You should see AMP in the display.
To activate an electrical component in Power Plus Mode:
1. If the electrical component is already grounded in the
vehicle, you can skip step 2.
2. Connect the auxiliary ground lead to the ground of the
electrical component.
3. Contact the probe tip to the positive terminal of the
component.
4. Press (+). The component should activate.
5. Read the display for the average current draw along with
the Min/Max measurements.
6. To reset the Min/Max Press R
VII
- VOLT METER MODE
The Volt Meter Mode is a passive mode. The (+) Power and (–)
Power buttons are not active so dynamic circuit testing cannot
be performed. This means, no Power will be activated to the
probe tip even when you press the Power buttons.
Volt Meter Mode monitors the probe tip and displays 3 voltage
measurements, Average, Min. and Max.
Min/Max can be reset by pressing the R button.
To access Volt Meter Mode from Power Probe Hook Mode:
1. Press SEL once.
2. Press D, 4 times.
3. Press SEL once.
4. Connect the probe tip to the circuit you want to
monitor and test.
5. Press R to reset the Min/Max

Now reset by pressing the
RIGHT ARROW button. Min is
now the same as Max.
When you touch the tip to the
positive battery post the aver-
age reading and the max will
read the same. The Min will
remain 0 since it recorded the
previous low.
