DESCRIPTION
The Narda Models NIM-511 and NIM-513 combine an un­precedented ease of operation with powerful measurement capabilities. It provides the industrial plant manager and safety professional with an accurate and inexpensive solution for proving compliance with regulations that cover exposure to RF radiation. Both models provide a complete measurement system comprised of an extremely easy to operate meter and a probe that contains sensors to measure both the electric (E) and magnetic (H) field components of an electromagnetic wave.
OPERATION
The NIM-511 and the NIM-513 were designed to make measurements a simple process that does not allow the most common mistakes to happen.
NO CHANGING PROBES TO MEASURE THE ELECTRIC AND MAGNETIC FIELDS - the probe contains two sets of sensors that separately measure each field. Simply press the E/H Field key combination to change the field that you are measuring.
NO RANGE CHANGES - the meter automatically displays a numeric value over the probe’s entire measurement range.
APPLICATIONS
Major safety standards worldwide require that both the electric and the magnetic field components (E and H fields) be measured for equipment operating below 300 MHz. Most high power industrial equipment operates at one of the frequencies allocated for Industrial, Scientific, and Medical (ISM) applications. Two ISM frequencies - 27.12 MHz and 13.56 MHz – are used extensively. The majority of heat sealers and induction heaters operate at 27.12 MHz while most semiconductor processing equipment operates at 13.56 MHz. The NIM-513 operates from 10 MHz to 42 MHz and is adjusted to the reference calibration frequency at 27.12 MHz. The NIM-511 has a much broader sensor that operates from 300 kHz to 100 MHz and is adjusted to the reference calibration frequency at 13.56 MHz.
RF energy can cause the body to be heated beyond its ability to thermally regulate itself. Since 1987 OSHA has had the authority to cite employers for exceeding the limits specified by “state-of-the-art, scientific standards.” OSHA has chosen the IEEE C95.1-2005 Standard for enforcement of non-ionizing radiation safety. This IEEE standard includes many changes from earlier standards and is considerably more complex. The Maximum Permissible Exposure (MPE) limits for Controlled Environ­ments are:
NO CONFUSING SCALES - simply read the digital display, including the unit of measure.
NO DIFFICULT ZEROING - Auto Zero is executed repeti­tively every 15 minutes.
NO FORGETTING THAT YOU ARE IN THE MAXIMUM HOLD MODE - the meter clearly displays the word “Max” when you are in the maximum hold mode.
