Fluke 5725A Amplifier
The 5725A from Fluke is a bench top amplifier for the 5700A and 5720A. It extends the 1000V range alternating voltage function up to 100 kHz and the direct and alternating current functions up to 11 Amps.
- 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 5725A 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.
- Mechanical damage — The 5725A contains several large transformers and is very heavy. Dropping or other impact damage from transport and shipping is not uncommon.
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.
* The 5725A can only be tested when connected to a 5700A or 5720A calibrator.
- 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 and 5725A. Run 5725A 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.
