Wavetek/Datron 1271 8½ Digit Digital Multimeter

The 1271 from Wavetek/Datron is a high performance, 8½ digit bench top multimeter. It can measure direct voltage and current, alternating voltage and current, and resistance. A rear input option is available for ratiometric measurements on voltage and resistance functions.

Common Failures

  • Misapplication of voltage or current — The 1271 can be damaged by sourcing high voltage into resistance or current functions.
  • Age — Very old instruments can suffer from age related failures caused by normal deterioration of components and assemblies over time.

Test Instructions

These instruments can produce or measure lethal voltages at their terminals. Testing should only be performed by qualified technicians.

Any failure or operational deficiency information available allows us to provide the best service. Please include any information available about failures and what function the instrument was in prior to failure.

Testing Steps

  • If the instrument is smoking or has a bad smell coming from it turn it off immediately and contact us for further instruction.
  • Power up the 1271 and let it warm up for 30 minutes. Run the fast test from the test button menu. If a failure occurs, note the error number/description and contact us. There are often multiple errors. Report as many as you reasonably can.
  • If the fast test passes, next run the full test from the test button menu. If a failure occurs, note the error number/description and contact us. There are often multiple errors. Report as many as you reasonably can.
  • For any functional or calibration errors not detected by the test operations, contact us for repair.
