The instrument is tested in accordance to EN 61326. However,
excessive distortion, slow average, transients or sags and surges on the
power line can affect the quality of the measurement. Non-standard
power fluctuations and excessive noise on the power lines will degrade
electronic components over time, reducing their life span. Thermo
Fisher Scientific recommends using power monitoring and conditioning
devices to ensure stable performance of the instrument.
Contact your local Thermo Fisher Scientific representative. See
“Technical Assistance” on page 6-8 for electrical equipment suppliers.
Power Monitoring Devices
Power monitoring devices help to decide whether it is necessary to
install a power conditioning device.
Power line disturbance analyzers are capable of detecting and recording
most types of power supply problems. These instruments provide a
continuous record of line performance by analyzing and printing out
information on three types of voltage disturbances:
•
Slow average
•
Sag and surge
•
Transient
In the first two cases, the duration as well as the amplitude of the
disturbance is indicated by time interval recording.
The power line must be monitored continuously for seven consecutive
days, 24 hours a day. If inspection of the printout indicates disturbances,
the test should be terminated and corrective action taken. Then, the
power should be monitored again as described above.
A variety of devices is available to monitor power supply quality. The
Leibert Corporation Model 3600 and the Dranetz™ 606 Series power
line disturbance analyzers are two devices capable of detecting and
recording most types of power supply problems.

Line monitors can be rented from electrical equipment suppliers. If
necessary, your local Thermo Fisher Scientific representative can assist in
interpretation of the results and recommend appropriate corrective
measures.
