Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC Caution
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may cause undesired operation
RF Exposure Warning
The equipment complies with RF exposure limits set forth for an uncontrolled environment. The antenna(s) used for this transmitter must not
be co-located or operating in conjunction with any other antenna or transmitter. You are cautioned that changes or modifications not
expressly approved by the party responsible for compliance could void your authority to operate the equipment.
IC Statement
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of the device.
Industry Canada - Class B This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set
out in the interference-causing equipment standard entitled “Digital Apparatus,” ICES-003 of Industry Canada. Operation is subject to the
following two conditions: (1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of the device.
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically
radiated power (e.i.r.p.) is not more than that permitted for successful communication.
RF exposure warning: The equipment complies with RF exposure limits set forth for an uncontrolled environment. The antenna(s) used for
this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Troubleshooting
The Check Load LED, , will flash when Go Direct Energy detects that there is
a potential between the red and black leads, but no load is connected. If you do not
have an external load connected, make sure the Load switch is set to Internal 30 Ω
Load. Using Go Direct Energy with this LED flashing will result in measurements
of potential, but since no current flows, no other quantities will be measured.
Resistance Values Fluctuate
When the current and voltage values are near zero, the resistance value is not
meaningful; it may fluctuate widely.
Thermal Protection
Go Direct Energy uses internal thermal fuses to protect the sensor from
overheating. For the Internal Load, if the potential increases above 5.5 V, the
thermal fuse will start to engage and internal resistance will begin to increase.
Over approximately 7.7 V, the thermal fuse will fully engage, meaning that the
sensor is overheated and all readings will go to zero. If this happens, disconnect all
wires and allow the sensor to cool for 10 minutes before starting another
measurement.
When using the External Load, the thermal fuse will start to engage if the current
increases above 1.1 A. Continued operation above this point will cause the thermal
fuse to fully engage, meaning that the sensor is overheated and all readings will go
to zero.
