For a counter, retain the measurement settings
Record the input channel, frequency or time-interval mode, signal level and gate or acquisition setting from the last use. If only one channel is affected, identify the others as untested or working according to the observations available. Include any overload, trigger or reference message. Saved settings and logs are more useful than changing several controls before the fault is documented.
Identify the timebase in use
Tell us whether the counter uses its own reference or one supplied by the rack. Include the external reference's frequency and connection if used. A missing reference indication needs to be considered with that arrangement; it does not by itself prove that the counter's internal oscillator has failed. Mark the reference generator as a separate asset if you want its condition reviewed too.
For timers, describe how the count begins and ends
A bench timer, stopwatch and time totalizer may use buttons, contacts or an electrical input to control the count. Describe the arrangement and say whether the fault is a missed start, early stop, reset, loss of memory or a steadily changing elapsed-time result. Give the interval at which it was observed. If a separate sensor starts the timer, identify it rather than treating it as part of the display.
Keep assessment and calibration in the same job record
Ask the repair estimate to identify the affected function, proposed parts and any settings that may be reset. Preserve the original configuration record before approved work. List the frequency points or time intervals needed afterward, along with the input arrangement. CC-4643 has specific time and frequency entries; a repaired counter's full rated bandwidth is not automatically included. Confirm the applicable function, range and report before returning it to acceptance testing.
Return the instrument to its assigned bench
For a shared IMT Sohna test bench, give the counter tag and the person responsible for reconnecting its reference. Label removable leads and adapters on the packing list. A job covering several Indian sites should keep the return address and certificate recipient beside each instrument, particularly when purchasing manages the order centrally.
