Troubleshooting

•
All the status lights are on, but the Field Unit sometimes makes long pauses
while taking phase reading.
This is usually due to communication problems on the cell network, on either
the Field Unit or Reference Unit end, such as a weak signal (-120 dBm to -
100 dBm), network congestion, busy cell towers, or signal interference from
high E-fields.
•
The Field Unit is not receiving the Hotstick Unit Signal.
Make sure the Hotstick Unit displays a solid green light. Orient the Hotstick
Unit faceplate toward the field unit. Orient the Field Unit lid so it is per-
pendicular to the direction of the Hotstick Unit. Elevate the Field Unit off
the ground (place it on a cement block, for example).
•
Phase angle readings appear inaccurate.
Accuracy of phase readings can be compromised in configurations where a
nearby phase interferes with the phase being measured. Situations include
cutouts, transformer banks, double circuits, circuits crossing, distribution built
under transmission, and secondary bushings on overhead transformers.
•
The touch screen is not responding properly.
The touch screen may need calibration. Navigate to the touch screen cali-
bration page and touch the crosshairs as directed.
PhaseTrakker Utility
•
The Utility is not able to connect to the Field Unit (or Reference Unit).
Make sure the Unit is turned on and the USB cable is connected. If the Util-
ity does not recognize the Field Unit or Reference Unit on the first attempt,
close the Utility, disconnect the USB cable, reconnect it, and start the Utility
again.
