Meter resets
Resets allow you to clear various accumulated parameters stored on your meter,
reinitialize the meter or reinitialize meter accessories.
Meter resets clear your meter’s onboard data logs and other related information.
Resets are typically performed after you make changes to the meter’s basic setup
parameters to clear invalid or obsolete data to prepare the meter for active
service.
Option modules reset
Perform an option module reset if your option modules are not communicating
with your meter.
During an option module reset, the option module may not operate normally, and
digital and analog outputs may change state.
WARNING
UNINTENDED OPERATION
Failure to follow these instructions can result in death, serious injury or
equipment damage.
Do not use the meter for critical control or protection applications where human
or equipment safety relies on the operation of the control circuit.
You can reset your meter’s option module bus using ION Setup or through the
display. This power cycles all the modules attached to your meter. If you have
queued firmware updates for option modules on your meter’s internal FTP site,
the firmware updates are performed.
By default, your meter is configured to automatically perform an option module
bus reset to help keep the option modules operating normally. Contact Technical
Support for instructions on changing this default configuration.
Available resets
You can perform various meter resets using ION Setup, the meter webpages or
through the display.
