Describe the failed test mode
Give the exact model and the selected two-, three- or four-terminal mode, or identify the clamp arrangement. Copy the displayed message and say whether it appeared during a field measurement or a check with a reference accessory. Include the selected frequency if the model offers a choice. Describe the observations already made; the repair enquiry does not require your team to repeat a test on a live installation.
Send an inventory of the kit
List each lead, reel, terminal adapter and clamp by its marking. A current-measuring clamp and an inducing clamp may look similar in a case but have different jobs. Include the check loop or box normally supplied with the kit if RTS requests it for assessment. Tell us about damaged sockets, incomplete jaw closure, water exposure or a charger problem when agreeing what needs to travel.
Separate the instrument fault from a site result
Keep the plant's earlier electrode results with its maintenance records. Send only the readings and conditions relevant to the reported tester fault, with the date and instrument identity. A repair assessment concerns the kit supplied to RTS. It does not establish a new earth resistance value for your factory or replace the installation owner's measurement and acceptance process.
Define the return checks before approval
Ask the estimate to state the parts or accessory work proposed and the functions to be checked afterward. A unit with resistance, leakage-current and noise-voltage displays may need more than one line on that list. Agree calibration points, modes and accessories with RTS, including the applicable scope where accredited results are required. Retain the repair reference with the next calibration certificate so a changed clamp or lead set remains traceable in your register.
Release a kit between maintenance visits
Give the next planned use date and identify any accessories that serve another tester. For a kit from IMT Faridabad, name the stores contact who will check the case contents on return. For dispatch from another state, agree the receiving address with RTS before booking the carrier.
