Fluke 5700A and 5720A Multi-Product Calibrator

The 5700A and 5720A from Fluke are high performance bench top, multifunction calibrators for calibrating 7½ and 8½ digit instruments. They can source direct voltage and current, alternating voltage and current, and resistance. A wide band voltage option is available with coverage to 30MHz.

Common Failures

  • Misapplication of voltage or current — The 5700A and 5720A can be damaged by sourcing voltage to any output terminal or by applying excessive voltage/current into resistance function.
  • Poor Maintenance — Over time or in dusty working environments dust and debris can build up on the filter and inside the unit. This can increase internal operation temperatures affecting reliability. It can also create leakage paths that affect calibration stability and operation accuracy. In the worst cases stray leakage caused by dust in the 5700A or 5720A can cause uncontrolled high voltage conduction within the instrument resulting in and significant damage.
  • 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 5700A or 5720A and run instrument self diag from the utilities 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 self tests pass, run cal zero from the calibration menu. If a failure occurs again note the error number/description and contact us.
  • If zero cal passes, run cal check from the calibration menu. If a failure occurs again note the error number/description and contact us. If the unit has been calibrated within the last two calendar years and there is a large calibration shift reported, this can be considered a failure as well.
  • For any functional or calibration errors not detected by the self test and cal operations, contact us for repair.
