Overview
The True RMS Ampstik has been developed specifically for measurement of AC current
in the electrical utility industry. The True RMS feature allows accurate measurement of
current even when the nominal waveform is distorted or when harmonics are present.
This instrument can be used remotely with any hot stick and universal chuck adapter or
can be hand held. The instrument has no moving parts and does not require clamping
onto the wire. The molded housing is water resistant and will withstand high physical
impact. The following specifications apply:

Safety Information
• The True RMS Ampstik is designed for use with a suitable universal hot stick.
• All precautions appropriate for the line voltage should be taken.
• The hot stick should be considered the sole voltage isolation device.
• For safety purposes the face plate, battery cover, chuck, and entire Ampstik should
be considered to be at the same potential.
• Putting the face plate, battery cover, chuck, or other parts of the Ampstik within
the air gap of adjacent phases or ground could cause a phase to phase or phase
to ground fault.
WARNING! Do not force the arms of the Ampstik Plus

Operating Instructions
The True RMS Ampstik Plus is controlled by a single push button switch located on the
front panel. Operation is as follows:
POWER ON - Press and release the control switch to turn on the instrument.
Startup Test
The Ampstik conducts a startup test to verify the sensors and circuitry is
functioning correctly. The following screens will display during the test:
If the test detects a failure, the display will show FAIL and a corresponding
code. See page eight for the failure code chart.
If the test determines the unit is functioning properly, it will move to normal
mode and is ready to take the first measurement. The display will show:
RUN Option - The reading continuously changes as the current changes.
The unit is immediately in the RUN mode after powering on. To place the instrument
into the RUN mode from a different mode, press and hold the control switch and
scroll to the option RUN, then release the control switch to engage the option.
To take measurements with the True RMS Ampstik Plus in the RUN mode, place
the conductor between the two arms and observe the display. For maximum
accuracy, be sure that the conductor is below the notches on the arms. If the
conductor cannot be placed below the notches, readings can be taken but the
accuracy may be lessened.
HOLD Option - Stores a Single Reading
Press and hold the control switch to scroll to the HLD option, and release the
control switch to engage the option.
The True RMS Ampstik Plus is now in the sample and hold mode, indicated by
the word “HOLD” appearing on the display. As shown below, nothing else will
display until a measurement is held:

CLEARING THE DISPLAY - Clearing the stored measurements
The True RMS Ampstik is now returned to the RUN Mode. Push and release
the switch to switch between RUN and HOLD Modes.
POWER OFF - Turning the instrument OFF
Press and hold the control switch to scroll to the OFF option. Release the
control switch. The True RMS Ampstik will turn itself off automatically after
several minutes of inactivity.

Automatic Backlight
The Backlight on the Ampstik is designed to automatically power on when the ambient
light is low. This helps users view the display in low-light situations. The light sensor
is located on the front of the unit. It's location is indicated with the light icon on the
front panel next to the switch. The backlight will continue to power on automatically
until the user manually changes the settings.
POWER OFF BACKLIGHT - Manually power off the backlight
Press the control switch until the following screen appears:
After releasing the switch, the display will momentarily show:
The backlight will stay off until the user manually powers it back on.
POWER ON BACKLIGHT - Manually power on the backlight
Press the control switch until the following screen appears:
After releasing the switch, the display will momentarily show:
The backlight will now automatically power on when light is diminished or until
the user manually powers it back off.
The user may see some flicker with the backlight if the backlight is on when under
artificial lighting. This is normal.

Battery Replacement
When the “LO BAT” indication shows on the display, the battery should be replaced.
The unit will continue to operate for a few hours. The Ampstik is powered by a single
9V battery. To replace the battery, remove the four screws on the battery cover at the
rear of the unit. Carefully insert a screwdriver blade in the notch and pry the cover out,
being careful not to damage the cover seal. Pull the battery out of the compartment
and separate the battery from the battery connector. To avoid breaking the battery
leads do not pull on the battery only. Install a fresh battery and reinsert the battery in
its compartment. Reinstall the cover by gently pressing it into place while pulling out
on the edges of the compartment, and reinstall the four cover screws. Take care to
avoid overtightening the screws. Always reuse the screws provided and do not damage
or lose the o-ring seal on each screw.
Cleaning
The Ampstik can be cleaned by wiping with a small amount of alcohol on a rag.
High Voltage Operation
This instrument is designed to operate in high voltage fields. However, difficulty may be
experienced when excessive corona to the instrument occurs. The unit may experience
over range and require power to be cycled or may lose a reading when in the sample
and hold mode.

Troubleshooting the Ampstik
Unit will not power on
Verify there is a fresh 9V battery in the unit.
Verifty the battery connectors have not been disconnected from the molded
housing.
Backlight Flicker
Due to the refresh rate of the light, some users may see flicker if the backlight is on
when under artificial lighting. This is normal.
Fail Codes
FAIL CODE "1": Break to the main current sensor
FAIL CODE "2": Break to a current sensor component
FAIL CODE "3": Circuit failure
FAIL CODE "4": Circuit failure
The above fail codes may also trigger due to dirty pin connections causing errors in
readings between the main board and molded housing assembly.
The unit will not enter into measurement mode if the self-test has any of the above
failures. The unit will need to be returned to SensorLink for repair evaluation.
