How to Reduce the Effects of Electromagnetic Interference (EMI)

Shielding Improves Performance

All conductors that carry current can be a potential source of electromagnetic interfer­ence (EMI). EMI can cause unstable readings (“rattling” digits) and in severe cases unread­able measurements. DMMs must be properly shielded to reduce these problems.

All Fluke meters are EMI shielded. Most have rigid nickel-graphite shells inside the case to reduce the effects of EMI.

It Pays to Calibrate Regularly

Measuring instruments are the ‘heartbeat’ of your company as they check and measure your production processes. They control the quality of your products and in the end are responsible for the success and the profitabil­ity of your business.

A regular check of your ‘heartbeat’ with traceable calibration equipment is essential. First, it ensures your quality always matches the customer’s expectation which is vital where ISO 9000 certification is involved. Second, regular calibration pays dividends. Fluke instruments are designed to hold accu­racy for one year before recalibration.

Consistent quality of your production output

  • Lower operating cost due to enhanced reliability
  • Address quality audit and reviews
  • Meet production control criteria
  • Measure inspection and testing results
  • Establish calibration traceability

Calibration Service

Our ISO/IEC 17025  A2LA Accredited Lab is equipped with the necessary instruments, standards, procedures, and personnel to maintain Fluke products at peak performance. We can also calibrate other manufacturers’ electronic instrumentation and electrical test equipment. Proper use of measurement standards is carefully and continually moni­tored through a corporate controlled audit program.

Since 1982 JM Test Systems has been providing NIST traceable calibrations to our customers. We are dedicated to a single goal: provide the best possible service for both our products and our customers.  JM Test recommends these Fluke Digital Multimeters:
