Overview
The True RMS Ampstik has been developed specifi cally for mea sure ment of AC cur rent in the electrical utility industry. The True RMS feature allows accurate mea sure ment of current even when the nominal waveform is distorted or when harmonics are present. This in stru ment can be used re mote ly with any hot stick and universal chuck adapter or can be hand held. The in stru ment 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 specifi cations 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.
1
FAIL
If the test determines the unit is functioning properly, it will move to normal mode and is ready to take the fi rst measurement. The display will show:
0.0
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” ap pear ing 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 fl icker with the backlight if the backlight is on when under
artifi cial lighting. This is normal.

Battery Replacement
When the “LO BAT” indication shows on the display, the battery should be re placed. The unit will continue to operate for a few hours. The Ampstik is powered by a single 9V battery. To re place 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 bat tery out of the com part ment and sep a rate 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 com part ment. Reinstall the cover by gently press ing it into place while pulling out on the edges of the com part ment, and reinstall the four cover screws. Take care to avoid over tight en ing 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 fi elds. How ev er, diffi culty may be experienced when excessive corona to the instrument occurs. The unit may ex pe ri ence 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 fl icker if the backlight is on
when under artifi cial 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.
