a) Voltage Testing in Power Probe
Hook Mode:
Voltage testing is as easy as contacting the probe tip to a
circuit and reading the display. There is no need to select the
voltmeter before probing because the Hook does that automat-
ically. The Hook also provides both the battery source voltage
and the probe tip voltage on the display screen for easy volt-
age comparing.
To test for voltage in Power Probe Hook Mode:
1. Take note of the preference parameters in the display.
2. Contact the probe tip to a voltage potential.
3. Take note of the difference between VOLT and BATT on
the display.
If the voltage difference is within the LED Voltage Drop Prefer-
ences, the Red LED will light and the HOT SHOT
®
symbol will
be present.
If the voltage difference is greater than the LED Voltage Drop
Preferences, the LED will not light.
4. Voltage is measured from 0 to 99.9 volts.

- POWER PROBE HOOK MODE
In Power Probe Hook Mode the “Smart Tip Advantage” gives you several new powerful tools to
help you fix electrical problems faster than any other circuit tester in its class. Why?
Because it automatically selects the:
RIGHT METER and the RIGHT FUNCTION for the RIGHT CIRCUIT condition.

b) Resistance Testing in Power Probe
Hook Mode:
Resistance testing is as easy as contacting the probe tip to
a circuit or a component and reading the display. There is no
need to select the Ohm Meter before probing because the
Hook does that automatically. It will also auto-range the deci-
mal point.
To test for resistance in Power Probe Hook Mode:
1. Contact the probe tip to a circuit or component with
resistance to ground. Resistance is measured and
displayed from 0 to 15 mega ohms. When Resistance is
less than 1 Ohm the Green LED will be on.
It is necessary to connect the ground lead to a chassis or other
common ground point to accurately measure 2 Ohms or less.
This will eliminate voltage drops within the 20 ft cable and
improve the accuracy.
When testing resis-
tance on some chassis
grounds even though
the ignition is turned
off, you may experi-
ence a millivolt potential
present. When that
happens, The Hook will
display a Dual Meter.

NEVER: Perform any tests on any SRS system without the system being completely disabled, modules unplugged and
simulators installed in place of all pyrotechnics. Doing so can lead to injury do to unwanted deployment and permanent
module damage.
