Safety Information: ALWAYS USE SAFETY GLASSES, OR EYE PROTECTION.
There are a number of safety features built in to the Power Probe Hook to protect the tool, the test circuit and you! Below
is a list and brief description of all the safety features.
1. Circuit Breaker:
Shuts off current to the tip if set value is exceeded. Plays tone specific to Circuit Breaker trip. In momentary you must
re-energize the Power Up buttons, in Latch Mode and Pulse Mode, power re-energizes automatically. Only available in
Power Probe Hook Mode (HookM) and Power Plus Mode.
2. Thermal Overload Trip feature
Powering up loads generates heat within a circuit depending upon the load and the duration. The Power Probe Hook has
built in calculated thermal protection. This means the higher the load and longer the duration, the higher the Power Probe
Hook will assume its internal temperature. The Power Probe Hook can drive a 25 amp load continuously but can only
drive a 65 amp load for about 8 seconds. If the thermal overload is tripped, the power will be terminated and the thermal
overload warning, “OVER TEMP” will appear on the display with a count down bar that will countdown for 10 seconds. You
will hear a tone specific to Thermal Overload. If the load is immediately repowered again after the Thermal Overload, the
run time will continue to shorten before Thermal Overload triggers again.
3. Overvoltage Alarm
If the voltage on the tip exceeds 99.9 Volts AC or DC the display will read Overvoltage and you will hear a specific tone.
The Hook has been rated for + or - 500VDC maximum to protect the tool. Available in all modes.
4. Sleep Mode
Sleep Mode is designed to preserve the life of your Display Back Light. Sleep Mode only works in Power Probe Hook
Mode when not being used. If you leave your meter in any other mode the Hook will stay active. The life of the Backlight
is 10,000 hours. Leaving the Hook Powered Up in any mode other than Power Probe Hook Mode will subtract from the
overall life and is not recommended. If you have powered up the Hook and it is sitting in Power Probe Hook Mode with no
action being taken for 10 minutes, your Hook will enter into Sleep Mode. At this time the Flashlight and Backlight will be
turned off and SLEEPING will appear on the display. If the tip senses a change or any button is pressed, the Hook will
wake up. It is ok to press any button when in sleep mode to wake it up. If a button is pressed when asleep no action will
be taken for the button pressed at that time only. The next press will be active. Available only in Power Probe Hook Mode.
5. Set Point Voltage Alarm
In Voltage Reference Mode only, if the voltage on the tip is different from the set voltage, a tone will sound.
6. Reverse Polarity Hook Up
The Hook has built in protection against reversing the polarity of the Hook Up Clips.
7. Fuse protection
The Power Probe Hook Up Clip set has built in fuse protection. Never try to connect your Power Probe Hook to a battery
without the proper supplied connector. Fire can occur! If the Hook Up Clip set is in proper working order, a light can be
seen glowing within the side of the connector body. If your Power Probe Hook is not powering up, check to see that the
light is lit. If not and the polarity is correct, you need to replace your Hook Up Clip set and have your Power Probe Hook
inspected for possible damage before using again.
The Ground Cable also has a fuse protection in the event that the Ground Cable comes in contact with a positive battery
source or it exceeds 25 amps continuous when using the Ground Cable as ground source. It has a replaceable 20mm
x 5.5 mm automotive fuse. To replace fuse, pry out fuse cover from Ground Cable connector body, remove old fuse and
insert new. Press back into Ground Cable connector body.
