Keep the input and display scaling together
Record the input signal or electrical quantity marked on the meter, its normal displayed unit and any programmed scaling. A meter showing pressure from a current signal has a different configuration from an ammeter connected through a transformer. If the display has an alarm, relay or retransmission output, identify which function was affected.
Send the exact error text or a photograph taken during normal use if one is available. Mention whether the fault appeared after a power interruption, configuration change or known damage. Leave removal and electrical access to the responsible site team. RTS can advise what model information is needed before an item is dispatched.
What would a replacement have to fit?
A display with the same front dimensions can have different terminals, supply requirements or output options. Give the complete suffix from the rear label and the existing panel cutout information if replacement is being considered. Preserve the last approved settings or configuration record with the fault note.
Ask for an assessment and an estimate before authorising parts. The model, condition and parts availability determine what can be proposed. If the display returns to a controlled process, identify who will restore the settings and what comparison is required before it is accepted back. Calibration can be quoted for the specified input and display points.
A meter removed from a shared switchboard
Put the feeder or station tag beside the meter asset number. Give the maintenance contact and the person who can approve the estimate. If the unit is being sent from stores rather than the installation site, identify the final return destination when discussing the repair.
